Loop Differences
Alpha Antenna has two different Magnetic Loop antennas. Click Here to learn the differences and similarities between this EmComm Loop and the Model 100W MagLoop.
Evolution of Efficiency
In 2014 Alpha Antenna offered a built-in LED tuning aid that would light up at approximately 5 Watts when the loop was tuned. We removed the LED, which activated at about 5 W, because it diverted power from transmission. Without the LED, more energy is radiated, improving antenna efficiency.

Works as advertised! I am completely satisfied with both the product and the service.
Excellent purchase. They accepted my proposed price, and delivered the antenna promptly. There was a problem with the legs, but Steven sent replacements quickly and they fit perfectly. Great service. The antenna works well though I am asking a lot of it, so far having to use it inside my house because of a strong HOA. It has me back on the air, though, after a 30 year absence! I am sure I will buy their products again. Thank you, Alpha Antenna.
