target=\"_blank\">W6LVP Mag Loop With T\/R Switch<\/a><\/li>\n<\/ul>\n<p>Here&#8217;s the product description of the Mag Loop with Power Inserter from the <a href=\"https:\/\/www.w6lvp.com\" target=\"_blank\">W6LVP website<\/a> (where orders can also be made&#8211;pricing identical to eBay):<\/p>\n<blockquote><p>The Wellbrook Model ALA1530LN-2 and DX Engineering (Pixel\/Inlogis) Model RF PRO-1B magnetic loops are both good amplified receive antennas.\u00a0 However, they are both expensive. \u00a0Shipping the Wellbrook antenna from the UK to the US adds another $100.<\/p>\n<p>Extensive side-by-side testing of the Wellbrook, DX Engineering, and W6LVP receive loops was compiled using simultaneous WSPR signal-to-noise reception reports on all LF, MF, and HF amateur bands. \u00a0In addition, extensive laboratory bench tests measuring gain, signal-to-noise ratio, and IMD were also performed. \u00a0Signal-to-noise ratio is important to pull weak signals out of the noise and IMD is important to reject distortion caused by nearby strong transmitters such as AM broadcast stations. \u00a0In both test regimens, all three antennas performed very well and without significant difference.<\/p>\n<p>The antenna version listed here includes a power inserter for use with receivers or with transceivers that have a separate receive antenna input. \u00a0If your rig doesn\u2019t have a receive antenna input, check out my antenna with a transmit\/receive switch.<\/p>\n<p>If you live in the shadow of one or more high-power AM broadcast transmitters, contact me about a special version just for you.\u00a0 Please contact me at <a href=\"mailto:lplummer@vcnet.com\">lplummer@vcnet.com<\/a>.<\/p>\n<p>W6LVP amplified receive-only magnetic loop antenna (boy is that mouthful):<\/p>\n<ul>\n<li>The W6LVP mag loop is a complete receive antenna system delivering top-of-the-line performance to amateur radio operators and SWLs \u2013 particularly for those with space and\/or budget limitations.\u00a0 It is a great complement to vertical or wire transmit antennas.\u00a0\u00a0 You have a knob to turn up the power but don\u2019t have one to turn up the received S\/N.<\/li>\n<li>Ten foot circumference (approximately 1 meter diameter) loop.\u00a0 Small size yields a natural stealth for HOA challenges.\u00a0 The loop is rigid enough to maintain its shape but flexible for portable transport or attic installation.<\/li>\n<li>Includes a low-noise, broadband amplifier covering 2200 (135 kHz) \u00a0through 10 meters (30 MHz) with no tuning or adjustment. \u00a0Perfect match for continuous tuning SDR receivers. \u00a0Great for contesters to quickly check all bands. \u00a0Greater coverage is possible at reduced performance.<\/li>\n<li>Light-weight antenna structure fabricated from furniture-grade PVC yields a strong but very light antenna weighing only 2 pounds (not including power inserter or power adapter).\u00a0 Great for both portable\/camping as well as fixed installations.\u00a0 Light weight and small size make for lower shipping cost \u2013 particularly compared to shipping from the UK.<\/li>\n<li>Directly compatible with a low-cost speaker tripod stand (not included) for portable operation.<\/li>\n<li>Compatible with light-duty rotator (recommended) for fixed operation.\u00a0 Loop can be rotated to null interference by up to 30 dB or enhance desired signals.<\/li>\n<li>Includes low-noise linear AC power adapter to generate clean 12 volts for the loop amplifier.\u00a0 Unlike the DX Engineering antenna which requires 24 VAC, power can be easily supplied by 12 volt batteries during portable operation. \u00a0Reverse polarity and short circuit protection provided by automatically resettable fuse.<\/li>\n<\/ul>\n<\/blockquote>\n<p>Eham reviews are very positive&#8211;so far, <a href=\"http:\/\/www.eham.net\/reviews\/detail\/13215\" target=\"_blank\">5 stars on all six reviews<\/a>.<\/p>\n<p>I also discovered this\u00a0short video of W9OY\u00a0comparing the W6LVP loop to a full size 80 meter vertical (verticals are much more susceptible to noise than
