My W6LVP is on a tripod with an overall height from ground of about 12 feet. \u00a0 This antenna has special filters to prevent strong medium wave signals from bleeding into HF.<\/p>\n<p>From the start, let me point out that my testing of the CHA-RXL was only on HF, not LF.\u00a0 There has been some robust discussion on the loop antenna group at Groups.io in which the low frequency performance of the Chameleon was criticized.\u00a0 Anyone wanting to read that debate should go to <a href=\"https:\/\/groups.io\/g\/loopantennas\" target=\"_blank\" rel=\"noopener\">https:\/\/groups.io\/g\/loopantennas<\/a> and do a search for Chameleon.<\/p>\n<p>I chose a number of frequencies in the 31, 25, 22 and 19 meter bands as well as one 21 MHz and 27 MHz frequency, roughly between 1830 and 1930 UTC.\u00a0 Propagation conditions have varied.\u00a0 My location in Maryland is quite noisy\u00a0and each day is a battle with electric lines and various noise sources from neighboring houses.<\/p>\n<p>Results from my first test, pitting the Chameleon against the Wellbrook can be seen in Video No. 1.\u00a0 Overall, the CHA-RXL is very sensitive, able to go head to head on most frequencies.\u00a0 But the CHA is the noisier antenna.<\/p>\n<h2>CHA-RXL v Wellbrook<\/h2>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"625\" height=\"352\" src=\"https:\/\/www.youtube.com\/embed\/vpNH8RD8UuY?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p>Then it was on to a comparison of the Chameleon to the W6LVP loop.\u00a0 Results of this test can be seen in Video No. 2<\/p>\n<h1>CHA-RXL v W6LVP<\/h1>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"625\" height=\"352\" src=\"https:\/\/www.youtube.com\/embed\/GZcRIVG6eLg?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p>So, some observations. While doing a good job keeping up with the Wellbrook on signal level, the Chameleon falls behind when it comes to noise.<\/p>\n<p>This can be seen on certain frequencies more than others, for example, reception of VOA on 15,580 kHz where the Wellbrook is far quieter, and on 15,300 kHz where Wellbrook is both quieter and delivers more signal.<\/p>\n<p>Similar can be seen on 15,140 kHz (Cuba).\u00a0 Perhaps the most striking example is WWV on 15 MHz where the CHA struggles while the Wellbrook far exceeds the competitor in clarity and signal level.<\/p>\n<p>The difference is more difficult to discern on some much stronger signals, for\u00a0example 15,770 kHz and the VOA frequency 11,610 kHz.\u00a0 On BBC on 11,810 kHz, the Chameleon actually sounded to be delivering more clearly than the Wellbrook.\u00a0 The same on 11,955 kHz.\u00a0 But then 11,975 kHz showed the Wellbrook winning the point again.<\/p>\n<p>On 15,300 kHz it seems as if the CHA and Wellbrook are equally matched in terms of signal level, but the Wellbrook still wins out on clarity.\u00a0 But on 11,995 kHz the CHA seems to be clearer while the Wellbrook has more noise.<\/p>\n<p>On 31 meters and 9,460 kHz which is a main frequency for Voice of Turkey the CHA performed quite well and was clear while the Wellbrook was noisier.\u00a0 On 9,635 kHz, the CHA and Wellbrook seemed about evenly matched.<\/p>\n<p>Down on 49 meters and 6,070 kHz Toronto the CHA seemed clear and less noisy than the Wellbrook.\u00a0 Up on 7,490 kHz the two antennas seemed to be evenly matched with the CHA seeming to bring in the signal better.<\/p>\n<p>Back up on 25 meters, at 11,850 kHz the CHA did quite well, but the Wellbrook won the contest.\u00a0 On 11,985 kHz, one of the stronger signals on the band the Wellbrook won by just a smidgen.\u00a0 Up on 13,670 kHz it was the Wellbrook winning on signal strength though the antennas seemed evenly matched on clarity.\u00a0 At 13,740 kHz the Wellbrook blew the CHA away on signal, which can be seen on the S-meter of the Collins.<\/p>\n<p>At 9,675 kHz it seemed an even match on clarity but the Wellbrook won on signal strength.\u00a0 A bit higher on 9,845 kHz the difference was very difficult to discern. \u00a0 And back at 15,580 kHz VOA from Botswana the CHA seemed to win the match.\u00a0 At 15,130 kHz the Wellbrook won on clarity and signal strength.<\/p>\n<p>Finally, back to 15,000 kHz WWV the Wellbrook won on signal strength but seemed evenly matched with the CHA on clarity.\u00a0 And on 13,630 kHz, a China frequency, the CHA seemed clearer.<\/p>\n<p>Then it was on to CHA and W6LVP comparisons. I should note what everyone knows about the W6LVP loop, which is that while it has shown itself to be a very quiet antenna, the sacrifice comes on signal level.<\/p>\n<p>On 11,800 kHz, a comparison of these two antennas did not reveal much.\u00a0 But then things started getting more interesting.\u00a0 On BBC 11,810 kHz the CHA shows far more noise than the W6LVP even though the CHA has more signal level.<\/p>\n<p>Here are the rest of the comparisons along with my assessment of which antenna wins out [* are instances where the W6LVP wins but by a closer margin].<\/p>\n<ul>\n<li>11,810 kHz W6LVP 9,420 kHz W6LVP<\/li>\n<li>11,640 kHz W6LVP 9,685 kHz W6LVP *<\/li>\n<li>11,670 kHz W6LVP 9,790 kHz Tie<\/li>\n<li>11,780 kHz W6LVP 9,855 kHz W6LVP<\/li>\n<li>11,900 kHz W6LVP 6,195 kHz W6LVP*<\/li>\n<li>11,965 kHz W6LVP 6,070 kHz W6LVP*<\/li>\n<li>13,630 kHz W6LVP 3,330 kHz CHA<\/li>\n<li>15,000 kHz W6LVP 11,810 kHz W6LVP<\/li>\n<li>15,580 kHz W6LVP<\/li>\n<li>21,525 kHz W6LVP *<\/li>\n<li>27 MHz (CB) W6LVP<\/li>\n<li>20,000 kHz W6LVP<\/li>\n<\/ul>\n<p>So, what conclusions to draw?\u00a0 Clearly, the Chameleon CHA-RXL competes better against the Wellbrook 1530 antenna than it does against the W6LVP, where differences are most striking.\u00a0 W6LVP wins almost every contest, which is why it is preferred by so many people whose listening takes place in noisy environments.<\/p>\n<p>This does not mean that W6LVP loops don&#8217;t come with compromises.\u00a0 Signal levels on W6LVP antennas are reduced to such an extent that some people, including me, place pre-amps back on the line to make up for the signal loss \u2013 this has to be done carefully so you&#8217;re not then re-introducing too much noise.<\/p>\n<p>Is the seemingly noisier CHA antenna due to the material used in construction of the loop?\u00a0 I don&#8217;t know the answer to that.\u00a0 The CHA is one rugged piece of aluminum in comparison with the smooth and light tubing on the Wellbrook and PRO-1B.<\/p>\n<p>It should be noted that W6LVP uses wide-diameter coax for the loops \u2013 LMR 400 and even LMR600.\u00a0 I find there is a slight but noticeable difference when using the wider diameter coax on a W6LVP, but not necessarily a major improvement.<\/p>\n<p>Which brings us around to the pre-amp box of the CHA itself.\u00a0 Much larger than the Wellbrook and W6LVP, this too has been discussed on the Groups.io loop antenna group, so I won&#8217;t repeat that here.<\/p>\n<p>Like Wellbrook, Chameleon can be expected to revise its pre-amp so anyone considering purchasing the antenna should be aware of this and act accordingly.\u00a0 As my comparisons show, where the CHA falls short is in the noise area rather than signal level, something Chameleon is aware of from other reviews.<\/p>\n<p>One of those reviews, by Dave Casler, can be found <a href=\"https:\/\/www.youtube.com\/watch?v=9_aMJ-E8Vpg\">here<\/a>.<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center;

But that critique focuses on LF.<\/p>\n<p>If Chameleon can upgrade its pre-amp to address what appeared to me in my tests of the antenna to be generally noisier reception in comparison with the Wellbrook and W6LVP, it will be more competitive with those providers, making the $500 or so price of a CHA-RXL more palatable.<\/p>\n<p>My thanks to Chameleon for providing the CHA-RXL to me.\u00a0 I certainly look forward to being able to test any newer modified pre-amp the company may come up with in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many thanks to\u00a0SWLing Post\u00a0contributor,\u00a0Dan Robinson, for the following guest post and review: Chameleon CHA-RXL:\u00a0 Is This Pro-level Loop A Worthy Competitor To Wellbrook and W6LVP? by Dan Robinson At the end of summer 2021, I took up an offer from Chameleon to test and review their CHA &#8211; RXL loop antenna.\u00a0 The company describes this [&hellip;]<\/p>\n","protected":false},"author":15,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[3607,3,129,43],"tags":[9270,9149,9569,2635,4357,3417],"class_list":["post-51077","post","type-post","status-publish","format-standard","hentry","category-antennas","category-news","category-reviews","category-shortwave-radio","tag-cha-rxl","tag-chameleon-cha-rxl","tag-chameleon-cha-rxl-review","tag-dan-robinson","tag-mag-loop-antennas","tag-magnetic-loop-antennas"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/pn3uc-dhP","jetpack-related-posts":[{"id":53868,"url":"https:\/\/swling.com\/blog\/2022\/09\/dan-reviews-the-new-chameleon-cha-rxl-pro-wideband-magnetic-loop-antenna\/","url_meta":{"origin":51077,"position":0},"title":"Dan reviews the new Chameleon CHA RXL Pro Wideband Magnetic Loop Antenna","author":"Thomas","date":"September 3, 2022","format":false,"excerpt":"Many thanks to\u00a0SWLing Post\u00a0contributor,\u00a0Dan Robinson, for the following guest post and review: The Chameleon CHA-RXL Pro:\u00a0 Improved Amp Board Raises the Game by Dan Robinson Back in 2021 I reviewed the CHA-RXL loop by Chameleon.\u00a0 This loop antenna is sold by major retailers such as DX Engineering, Gigaparts and Chameleon\u2026","rel":"","context":"In &quot;Antennas&quot;","block_context":{"text":"Antennas","link":"https:\/\/swling.com\/blog\/category\/antennas\/"},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/swling.com\/blog\/wp-content\/uploads\/2022\/09\/Chameleon-CHA-RXL-PRO-Preamp-1.jpeg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/swling.com\/blog\/wp-content\/uploads\/2022\/09\/Chameleon-CHA-RXL-PRO-Preamp-1.jpeg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/swling.com\/blog\/wp-content\/uploads\/2022\/09\/Chameleon-CHA-RXL-PRO-Preamp-1.jpeg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/swling.com\/blog\/wp-content\/uploads\/2022\/09\/Chameleon-CHA-RXL-PRO-Preamp-1.jpeg?resize=700%2C400&ssl=1 2x"},"classes":[]},{"id":47861,"url":"https:\/\/swling.com\/blog\/2021\/02\/the-new-chameleon-cha-rxl-amplified-magnetic-loop-antenna\/","url_meta":{"origin":51077,"position":1},"title":"The new Chameleon CHA RXL amplified magnetic loop antenna","author":"Thomas","date":"February 19, 2021","format":false,"excerpt":"Many thanks to SWLing Post contributor, Chris Rogers, who writes: Hi Thomas, An interesting new product has just been released for pre order, a US made Chameleon model CHA-RXL receive loop covering from 137 kHz -30 MHz.
