No other loop is as highly refined than the Alpha Loop, which is so perfectly balanced that it handles 100 Watts PEP SSB *.

The Alpha Loop with 'Easy Tune' 6:1 reduction drive is designed to operate from 10 through 40 meters where it is rated at 50W CW, 25W Digital, and 100W PEP SSB *.

* When Mic Gain is adjusted to not peak your meter when SSB is used.

There is also an optionally available Booster Cable that enables you to use 20W PEP SSB on 40/60/80 Meters. The outer loop has over 21 feet in total length with the Booster Cable installed. This gives the Alpha Loop more surface area, which provides for greater skin effect that equals greater efficiency, than any manufactured loop on 40, 60, & 80 meters.

This antenna is a small (transmitting) loop, so there are no taps on coils and no counterpoise wires needed. It has a built in tuner with a 6:1 reduction drive that allows you to easily match the antenna for transmit and receive from 7 MHz to 29.7 MHz or 3.5 MHz to 7 MHz when the optionally available Booster Cable is installed. High noise rejection is also one of the favorite features of this antenna for many operators in RFI prone environments.

Deployment video of the antenna

When we released the 2018 version of the Alpha Loop, we conservatively rated it at 30 watts. Extensive testing has enabled us to announce that all 2018 30W Alpha Loop antennas purchased after January 1, 2018 can accept the new power levels. To remain safe on many levels from the significant power a 100 watt magnetic loop presents, there is no upgrade path that we have found for all Alpha Loop systems purchased before January 1, 2018.

We are dedicated to improving all of our antennas. Specifications and descriptions are subject to change without notice.
