Ferrite-Bar-Antenna-PL-365-GP5SSB

If you own a Tecsun PL-360, PL-365 or a CountyComm GP5/DSP or GP5/SSB, you might take note of this large ferrite bar antenna offered by a Greece-based seller on eBay.

Ferrite-Bar-PL-365

As you can see in the image above, this antenna is substantially larger than the stock MW antenna supplied by the manufacturer. According to the seller, this ferrite bar antenna has a 10 – 25 db gain over the stock external antenna. I imagine its ability to null unwanted signals is also much better.

The price is about $40 US shipped internationally.

Active Ferrite Rod Antenna (Photo: ON2NLT)

In my recent post, The truth about portable amplified shortwave antennas, I argue that small, portable amplified antennas are, by and large, ineffective. The post comments are interesting, however; many readers agree, and some tout the Sony ANT-LP1 as worthy, but Mike made the following comment about his amplified antenna:

The one active antenna that I have been pleased with is one I built myself. The design was by ON2NLT and uses a ferrite rod, so it is somewhat directional. Rotating the unit (it is very compact) often allows nulling out noise or interference. You have to be careful not to crank up the gain too much though, or you will amplify the noise floor.

Looks like a fairly simple project. Thanks, Mike!
