MAKE OFFER! New! 7 Band HF 10-40 Meter Alpha Multiband Loop antenna
The rugged & waterproof Multiband Loop is a complete HF antenna that transmits from 10-40 meters and has low noise receive capabilities from 7.0MHz to 29.7MHz. It can be assembled in less than 60 seconds even with thick winter gloves on. It is directional, packable into less than 25% the space of any other, and at 1.3 Kg (3 pounds), which includes Tripod, Bag, and Antenna, it is the lightest Complete Magnetic Loop ever made. The Multiband Loop is the only manufactured Magnetic Loop antenna that is also optimized to maximize Magnetic Loop properties on 20-40 meters, while then acting as a small transmitting loop on 10-17 meters. To enable the highly desirable properties of a Magnetic Loop Antenna, the circumference of this antenna's outer loop is slightly smaller than 1/10 of a wavelength for 20 meters. All other manufactured loops do NOT meet the 1/10 Magnetic Loop design standard on 10-30 meters.

This is because other antennas are greater than 1/10 of a wavelength on all bands except 40 meters, and some larger high dollar loops even exceed 1/10 of a wavelength on 40 meters. Ironically, some loop manufacturers claim higher efficiencies because their coax is longer. In truth, after the 1/10 Magnetic Loop design standard is exceeded, a small transmitting loop begins to exhibit the properties of just a random wire of coax tuned by a capacitor. Basically, as the size of the outer loop increases, the greater the losses become for all of the desirable characteristics of a magnetic loop antenna.

Proven Times Microwave LMR-400 design for the construction of the outer & inner loops - Rigid inner loop with convenient SO-239 where you connect your coax. This Alpha Antenna features fast and easy tuning, which means you just listen for the loudest noise to come out of your rigs speaker as you turn the tuning knob on the Alpha Multiband Loop , and then just tweak for the lowest SWR using your rigs SWR meter or an Antenna Analyzer. 7 Band HF 10-40 Meter Alpha Multiband Loop antenna" is in sale since Friday, July 07, 2017.
