Portable Powerhouses: Comparing the Bonito Boni Whip and Wellbrook ALA1530LNP Antennas

One fits in a car (well, most vehicles anyway) and another easily slides into a small daypack; which antenna is best for DXing on-the-go? The ALA1530LNP and Boni Whip are at opposite ends of the portability scale (as well as the price scale).

I’ve written about the ALA1530LNP in the pages of the SWLing Post before, where I compared it against another Wellbrook loop antenna on extremely weak medium wave signals. The ALA1530LNP currently costs $413 USD including shipping to the Seattle USA area where I live.

More recently I’ve been intrigued by UK Oxford Shortwave Log’s (YouTube) excellent videos demonstrating the DXing prowess of the very compact, highly portable Bonito Boni Whip antenna. Through a Bonito USA dealer I was able to purchase the Boni Whip at an attractive $99 USD price (plus $11 shipping).

So, is it fair to compare “apples and oranges”? Maybe not, but it was fun and interesting nonetheless to take both antennas to the countryside to find out how they perform head-to-head in a portable situation. My destination was a small forested campground, in a valley east of this beautiful Mount Rainier, Washington scene:

In mid-July, Tipsoo Lake near Mt. Rainier is still surrounded by snow.

Over the course of three days I compared the two antennas with these receivers:

  • Eton E1XM
  • Sangean ATS-909X
  • Elad FDM-S2

I set up the E1XM and ATS-909X receivers on a portable tote box with the antennas powered by SLA gel cell batteries and using a two-way antenna switch for instant comparisons.

Each antenna was mounted on its own “pro” speaker stand and separated 60 feet from each other. The antennas were connected to receivers by equal 100 foot lengths of RG-58 coax cable, and were over 80 feet away from my laptop computer (the only noise source in the area).

In keeping with the uber-portable theme of the Bonito antenna, I used a very compact 1.2Ah SLA gel cell battery for its power injector (junction box). Since the antenna consumes a mere 45 ma. of current, this small rechargeable battery will power the Boni Whip for many, many hours.

The Wellbrook ALA1530LNP requires a still reasonable 200 ma., and I brought along a much larger battery to power it.

Below are a selection of 30-second medium wave and shortwave recordings, each one of them beginning with the Boni Whip and switching to the ALA1530LNP midway through the recording.

EDIT 7/14/2017: 11905 kHz, Reach Beyond Radio, Kununurra WA Australia (tentative; listen for the Aussie-accented weather forecast at the end of the Wellbrook loop portion. This catch was at 03:48 UTC, which matches up with the brief English language broadcast in Reach Beyond’s schedule for 11905 kHz. This catch does not appear to be China National Radio as  I first thought.)

Boni Whip vs ALA1530LNP – Elad FDM-S2

These 30-second videos are from the Elad SDR’s FDM-SW2 software. As above, the first half of each recording is the Bonito antenna followed by the Wellbrook loop. If you maximize the playback of a video to full screen you can read the signal-to-noise ratio (SNR) change (“Delta”) as the antenna is switched to the ALA1530LNP.

The compact Boni Whip is a unique commercial design of “mini whip” antenna, pioneered by Roelof Bakker, PA0RDT some years ago. As with all these compact e-field antennas they can be a significant “noise sponge”, collecting any RFI or interference in the area. This is especially true if the coax shield is not grounded. Despite using two Bryant/Bowers design of RF chokes in series, the Boni Whip’s reception was degraded by RFI emitted from my laptop over 80 feet from the antennas. The RFI was quite a bit worse without any RF chokes in-line. You’ll note though that even the Wellbrook loop received some interference from the laptop on the higher shortwave frequencies.

4840 kHz, WWCR, Nashville TN USA

5985 kHz, R. Taiwan Intl. via WYFR, FL USA

6090 kHz, The Caribbean Beacon, Anguilla (distorted, with transmitter problems)

Observations. On medium wave (E1XM examples) the directionality of the Wellbrook loop could be noted on one, maybe two of the three recordings. This can be a benefit–or not–depending on your goal. (I did not rotate the Wellbrook loop to null or peak any specific MW signals.) The omni-directional Boni Whip would not be the antenna of choice for a hard-core medium wave DXer; however, it is extremely compact and lightweight for camping and travel if you will be DXing or SWLing on shortwave also. The Wellbrook though is highly regarded as a medium wave DX antenna, especially when used with a rotor to take advantage of its sharp broadside nulls.

I didn’t test the Boni Whip on long wave, but Oxford Shortwave Log and others report it does very well on LF. I tried the antenna on FM frequencies against the Eton and Sangean’s telescopic whip antennas but in every case the reception was worse on the Boni Whip.

As I expected on shortwave, the ALA1530LNP greatly outperformed the Boni Whip on some signals. On others, reception was extremely comparable! The 3330 kHz CHU recording surprised me with the neck-and-neck reception. At this tropical band frequency there may have been some directionality to the signal, and the loop may not have been oriented optimally. The 4960 VOA reception was also very close.

I was disappointed, but not surprised at the RFI pickup of the Boni Whip when using my laptop and the Elad SDR receiver. The two RF chokes tamed the spikes and hash a bit, but removal was far from complete. The Wellbrook wasn’t always “clean” in this regard though.

Final notes. I think the Boni Whip is an extremely high value in a “jack of all trades” very portable antenna. Like Oxford Shortwave Log and others, I find this active antenna’s noise level to be extremely low, helping its sensitivity reveal weak DX signals in a surprising fashion. I would not hesitate to use this antenna away from noise sources when traveling with a non-computerized receiver. Well done, Bonito!

Is the Wellbrook ALA1530LNP worth four times the Boni Whip’s USA price? To the serious DXer who has no room for large passive antennas (Beverages, phased delta loops, DKAZ, etc.), the 1-meter diameter Wellbrook is clearly in a class of its own. By the way, the US Dollar to UK Pound ratio has improved in recent months, so the Wellbrook is an improved value for USA radio hobbyists now.

Truly this was an “apples to oranges” comparison, but I thoroughly enjoyed using both models. I welcome your comments, particularly if you also own both of these fine antennas.

Used Bonito Boni-Whip and MegaLoop at Universal Radio

If you’ve been considering either the Bonito Boni-Whip or MegaLoop NTI ML200, you might check out these second-hand units at Universal Radio:

While browsing Universal’s used list this morning, I noticed the two Bonito antennas. Both are listed in “good” condition and Universal Radio backs their used equipment with a 60 day limited warranty. The Boni-Whip price is $119.95 and the Mega-Loop $285.95.

SWLing Post contributor, Clint Gouveia, has been most impressed with the Boni-Whip–check out this recent review with videos.

I was mighty tempted to purchase this used Boni-Whip, but I’ve been so busy on the road lately, I haven’t even had an opportunity to put Steve Yothment’s homebrewed mini-whip antenna on the air and I’ve had it since early March!

The Megaloop ML200 is a very portable magnetic loop antenna.  I’ve used one on a couple of occasions and really appreciated the noise rejection. It’s much easier to pack than a loop with a rigid antenna element.

$295.95 is a great price for the ML200 which typically sells for 369 EUR via Bonito in Germany.

The Bonito Boni Whip goes from strength-to-strength: hardcore DXing in compact package

Hi there, subscribers to the Oxford Shortwave Log YouTube channel and regular readers of this excellent website will be aware that I have been using a Bonito Boni whip E-field wideband antenna for a couple of months now. You may have seen my previous post here, detailing some excellent initial DX results achieved with the Boni Whip. What makes this antenna so compelling for a DXer such as myself is simply that it’s so light and compact; I can literally take it anywhere. Currently it lives in a small flight case (see above & below) on the back seat of my car, with either my Sony ICF-SW55 or Eton Satellit, a home-brew battery pack (that literally cost pence) and some peripheral bits and pieces; spare batteries, cables etc. I think it’s probably already clear that if you consider the Boni Whip’s performance as a function of portability and price, it’s out there on its own – I’m not aware of another antenna that can match it. Of course, there are H-field antennas, such as the excellent Wellbrook active loops that will effectively reject QRM, if that’s an issue for the user, but at a significant cost delta.

 

Since my last posting, I have continued to use the Boni Whip regularly on my DXpeditions and upload the reception videos to my YouTube channel. I have been nothing but totally impressed with this antenna, to the point that I’ve actually been surprised by the signals I’ve caught and recorded with it. Recent catches include a number of low-power stations from Brazil, including Radio Bandeirantes – Sao Paolo, Radio Voz Missionaria – Camboriu (on the 49 and 31 metre broadcast bands) and Radio Aparecida. Some of these signals are incredibly difficult to hear in Europe at all, let alone well and yet the ultra-compact Boni-Whip running off AA batteries, coupled to the (equally brilliant) Eton Satellit managed it with aplomb. Other catches include Zambia NBC Radio 1 – Lusaka and a signal from Bangladesh Betar that sounded as if the transmitter was 5 miles down the road!

All-in-all, I’m extremely satisfied with the performance of the Bonito Boni Whip and highly recommend it to those DXers requiring a high-performance, compact antenna, for use at home in electrically quiet environments or on any DXpedition. You certainly won’t be disappointed.

Please find embedded reception videos below and text links that will take you to the Oxford Shortwave Log YouTube channel. Thanks for reading/watching/listening and I wish you all great DX.

The Bonito Boni whip: proving to be excellent portable antenna for DXing

Hi there, if you’re a subscriber to the Oxford Shortwave Log YouTube channel, you will be aware that I have been using a Wellbrook ALA1530 H field antenna, for 15 months or so, with (at times) excellent results. A while back I was on the lookout for a second antenna, however at more than £250, I couldn’t justify purchasing a second Wellbrook. Ultimately I splashed out on the Bonito Boni whip E-field wideband active antenna (20 kHz to 300 MHz) and with a very compact form-factor suitable for DXpeditions/portable operation in general, the Boni whip definitely ticked all the boxes. Furthermore, with reasonable second and third order intercept points of +55 and +32.5 dBm respectively, the Boni whip, on paper at least, looked like a pretty good buy at around £100.

 

Initial testing at home confirmed, perhaps not surprisingly that the Boni whip could not match the SNR provided by the Wellbrook ALA1530 in a noisy, urban environment. However, less predictably, the Boni whip has proven to be a truly excellent antenna away from the ubiquitous blanket of ‘electrosmog’ at my QTH. Furthermore, it really is so compact, I simply leave it in the car in a small flight case, with a portable and connectors etc. for ad-hoc listening sessions. Since returning from my most recent trip to Brazil, I have had a chance to review my most recent catches with the Boni whip, some of which are realy pleasing and most definitely underline the excellent performance of this diminutive antenna. In particular, signals from Radio RB2  on 11935 kHz and Radio Aparecida on 11855 kHz, both low power Brazilian stations, are testament to how sensitive the Boni whip is in an electrically quiet environment. Check out also the quality of longwave signals from Poland and the  Czech Republic – simply amazing for such a physically short antenna. Finally, there’s a personal first from Lusaka, Zambia, Voice of Hope Africa on 13680 kHz. All the more rewarding that this was actually copied in my work office!

I hope you found this article interesting. There are embedded reception videos below and text links for all, which will take you directly to the relevant video on the Oxford Shortwave Log YouTube channel. Thank you for reading/watching/listening and I wish you all excellent DX!

DXpedition antenna testing: the Bonito Boni whip and a 240 metre barbed wire fence

 

Hi there, a few days ago I posted some reception videos comparing the performance of the Boni whip with a 30 metre longwire antenna at home, with a further check against the performance of the H field Wellbrook ALA1530 active loop. The conclusion of those tests was essentially confirmation that E field antennas don’t usually perform very well under a blanket of ‘electrosmog’ and that only on Longwave, did the Boni whip prevailed over the longwire; otherwise there was no usable difference in performance between the two.

                         Sony ICF-SW55 receiver                                     ‘Quiet’ location for Boni whip test

This prompted a number of my subscribers to ask when I would be taking the Boni whip on a DXpedition for an outdoor test against the Wellbrook and either a substantial longwire, or the 200 metre Beverage. Time is limited right now for a full test, however, I managed to throw together a kit of parts necessary to run a quick set of comparison tests with the whip, against the barbed wire fence I use for ad hoc DXing when out walking the dog! Over a period of an hour or so, I managed to copy a few stations on 31 and 49 metres and thus recorded signals using the Sony ICF-SW55 receiver with the Boni whip and barbed wire fence. Now previously, I have used that fence as an antenna for the excellent little Tecsun PL-310ET, with some nice results. However, after this series of tests, my views on the fence have changed a little. Obviously it might be somewhat directional and earthed along it’s length, neither of which I’ve checked, however, notwithstanding these performance-related factors, the performance of the whip which at home had been terrible, surprised me greatly. Text links to a set-up video and the reception videos on my Oxford Shortwave Log YouTube channel follow directly below, with embedded videos at the end of the post. 

Finally, if you’re looking for a well performing, compact and portable active antenna for outdoor use in quiet environments and of course, DXpeditions, I would definitely recommend the Boni whip. Just bear in mind that the SNR it delivers at home might not be usable for anything more than casual listening.

Thanks for watching/listening/reading and I wish you all great DX!
