10-80 Meter Magnetic Alpha Loop Antenna handles 100W on 10-40M and 20W on 40/60/80 Meters when the included Booster Cable is installed.

Summary:
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 Booster Cable is installed. High noise rejection is also one of the favorite features of this antenna for many operators in RFI prone environments.

More EFFECTIVE & EFFICIENT than any other manufactured loop:
The Alpha Loop is a 10-40 Meter transmit/receive magnetic loop antenna, which handles 100 Watts PEP SSB, 50 Watts CW, and 25 Watts Digital. This enables the Alpha Loop to be heard and be more Effective than any other manufactured loop. Other loops just can’t take the power that is often needed to break through or 'make the trip', but instead they try 'compensating' for lack of design or they limit you to sub-par performance with 10 watts CW (25 watts SSB) or less of power handling capabilities.

When the the Booster Cable is installed, a double loop is formed that narrows bandwidth, which is proof of increased efficiency. The outer loop then too has over 21 feet in total length, which results in more surface area for increased skin effect and this also increases efficiency. The result of both of these design features is an antenna that that is more Efficient than any other manufactured loop on 40, 60, 75 & 80 meters.

ADDED BONUS! The included Booster Cable transforms this Alpha Loop into the largest=added efficiency of all manufactured portable Magnetic Loops. When you receive the 10-80 Meter Alpha Loop, just replace the default 10-40M outer loop with the Booster Cable.

Included:
Tripod and Bag
Alpha Match with 6:1 Vernier Reduction Drive inside a high voltage enclosure
Inner Loop featuring our uniquely available patent pending Shielded Faraday Coupling Loop
Outer Loop with continuous coverage from 7 MHz to 29.7 MHz 100W PEP SSB
Booster Cable with continuous coverage from 3.5 MHz to 7 MHz at 20W PEP SSB (NOTE - Booster Cable installs in Series with the Outer Loop)

Analysis:
Alpha Antenna provides you with real world results at the center of each band, at a height of one loop diameter, using no RFI choke. We do not just show you the 'sweet spot' where analysis provides the best results on a specific frequency. We also do not guess at how a loop is made and then simply use "a calculator used to arrive at the gain figures of the competitor’s loops". Nor do we change the height and add a RFI choke to remove SWR issues. So, here is the real world analysis for the Alpha Loop.
