58 Antennas: Loop Horizon Loop Antennas Capitalizing on the popularity of HF magnetic loops, Bushcomm’s two Horizon Loops are a great solution for HF operation in a limited space. Whereas many popular magnetic loop models are receive only, these antennas actually allow tight-band transmit capability. Reception is characteristically quiet and transmission is remarkably eff icient. They feature a durable, yet lightweight, aluminum loop and come with installation hardware. Horizon Loops handle 125 watts PEP. BCM-LOOP-20 Horizon Loop, 20-10M, 29" OD ...........................................$399.99 BCM-LOOP-40 Horizon Loop, 40-10M, 54" OD ...........................................$429.99 BCM-LOOP-20 Automatic Magnetic Loop Antennas Own a stealthy loop antenna that can really handle the power. DX Engineering is proud to off er popular and proven “Loop Antennas by I3VHF”—the BABY Loop model (6.6-29.8 MHz) and MIDI Loop (3.5-14.5 MHz), both manu- factured to the highest standards by Italy's Ciro Mazzoni. They’re compact, quiet, easy-to-install and ideal when you’re dealing with limited space but still want higher-power handling compared to other transmitting loops. Perfect for stealth HOA, these solidly constructed aluminum antennas include the ATU 2.0 Automatic Tuning Unit to resonate the loop throughout their wide frequency ranges: 80 through 20 meters for the MIDI Loop, 40 through 10 meters with the BABY, without any coverage gap. The updated ATU 2.0 now features a black background display with amber characters. The ICOM-CAT-CBL interface cable for the ATU 2.0 unit in BABY, MIDI, and STEALTH loop antennas connects Icom transceivers equipped with computer ports for frequency specific automatic tuning. Other brand radios are interfaced to the ATU 2.0 with RS-232 cables. For complete details, enter “MZZ” at DXEngineering.com.

MZZ-BABY-A AlexLoop Ham- Pack Portable Magnetic Loop Antenna System This portable magnetic loop antenna makes an excellent solution for the outdoor radio operations enthusiast and the space-restricted ham. The HamPack system comes with the widely acclaimed AlexLoop. This lightweight and compact (three foot in diameter when assembled) transceive QRP magnetic loop antenna for 40-10 meters can be easily taken into the field and assembled in less than two minutes. Bring it along for stealthy operating while on vacation, mounted in a window, or on a balcony. Features include maximum power of 25W PEP SSB, 10W FM/AM and Digital; low-loss PL-259 connectors; and antenna tuning in five seconds on any frequency between 7 and 30 MHz. 8.5' coaxial cable with BNC connector included. The antenna comes with a full-size backpack featuring two reinforced pouches—one for accessories and the other to accommodate any size QRP rig. The large, precisely- printed scale that displays the range of frequencies, a very smooth geared tuning system, and the exclusive AlexTune LED Indicator make tuning this portable magnetic loop super easy. The AlexTune also works with other small transmit magnetic loop antennas (from 2-20W on SSB and 1-10W on CW/FM/Digital) that use PL-259 connectors and a coaxial cable radiator like the AlexLoop.
