The 10 through 80 Meter Alpha Loop with 6:1 vernier reduction drive offers you a light 10-40 Meter 30 watt PEP SSB (approximately 15 watts CW) transmit/receive antenna in a small package that deploys in 5 minutes. The 40-80 meter Booster Cable that takes a few more minutes to install enables coverage from 3.5 through 7.3 MHz at 20 watts PEP SSB on 80 meters, while simultaneously boosting performance on 40 meters beyond what all other Small Loop Antennas can deliver.

As this antenna is a loop, so there are no taps on coils and no counterpoise wires needed. It has a built in tuner 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 (80 Meters through 10 Meters). High noise rejection is also one of the favorite features of this antenna for many operators in RFI prone environments. We recommend placing this version upon your tripod's 1/4 20 top threaded mount or that you purchase one of our tripods to deploy it.

"I just had a reasonably long QSO on 80 m from Adelaide South Australia to Caragabal NSW which is a distance of almost 1000 KM. The alpha loop was sitting on my desk next to me inside the house (under the iron roof). My signal was 5/9. Now I really believe it works - Joe VK5FBHE".


The Coaxial Alpha Loop Antenna appears as a large resonant circuit to your transceiver. The large outer loop is the inductor of the circuit, which is tuned with the capacitor in the Alpha Match. Due to the large size of the inductor, radiation of your signal very easily takes place.

Booster Cable

The AlphaLoop Booster Cable is connected in series with the base outer loop, which enables your 10-40 meter Alpha Loop Antenna to transmit and receive on 40, 60 & 80 meters.
