The 3-foot-wide base Alpha Loop that covers 10 to 40 Meters is remotely tuned and rated at 100 watts PEP SSB, 50 watts CW, or 25 watts digital, which are each based on duty cycles.Use our Make an Offer Program and Click this button if you can’t afford full price.Make An Offer (Without Options)This stealthy magnetic loop antenna with direct wire remote control is a tuned circuit, so there is no need for radials or counterpoise. Perfect for Attic, *Mast, EmComm Trailer, or anywhere when reliable and quiet communications is required in a small space.Included Matching network that is remotely and manually tunes the antenna. Remote control with power supply. 50ft of coax and 50 ft of remote-control cable. Inner Loop with SO239 for connecting the antenna to your equipment. Outer Loop with a circumference of 8′ 6″, which has a diameter of 3-feet. Mounting hardware (2- 16 inch cross supports, top & center mast mounts, and u-bolts, which brings all the components together and *installs on your mast that can have a diameter up to 1 1/4 inches.Helpful Tips Minimum mounting height is 1 loop diameter high (about 3 feet or higher). Alpha MagLoop antennas can be placed high enough to see above and past obstacles. Attic installations with asphalt shingles typically see only a little more than 1 S-Unit of loss. Can be mounted horizontally on *your mast to enhance Omnidirectional and NVIS performance. Total maximum tuning time from 7.0MHz to 29.7MHz is 90 seconds when the tuning speed knob is turned completely to the right. Pressing and Tapping the Left or Right button allows for remote and manual tuning of the loop.

Additionally, it maintains a directional null through the center of the loop, which is advantageous for effectively minimizing local noise sources.IP 65 RatingThe enclosure at the antenna that contains all of the tuning hardware is dust-tight and protects against water jets from any direction from damaging the internal components.Remote Tuning tips When using the remote control, total maximum tuning time from 40 meters through 10 meters is 90 seconds. This is with the tuning speed knob turned completely to the right for maximum tuning speed. If you don’t have any idea what frequency you are on, then pressing either the left or right button for 90 seconds resets the loop to either the lowest or highest frequency. Tapping the left or right button on the magnetic loop’s remote control allows for incremental stepped tuning. Make a note on whether your loop is either tuning up in frequency or down in frequency when pressing either green or red button, as the circuit can send a forward/reverse command that is dependent upon how your wall-wart is plugged into the wall.Deployment examplesIncludes images of antenna installed on customer supplied mast. *5.0 Based on 11 reviews5 star100100%4 star0%3 star0%2 star0%1 star0% Searchalpha antenna1-5 of 11 reviewsMost RecentMost Helpful Protected_User_4cf926fb Verified owner April 2, 2026 100W Base 10-40M Remote Tune MagLoopVerified review - view originalExtremely happy with this magnetic loop antenna. Remote tuning also does away with annoying hand-capacitance effect! Build quality is up to the usual excellent standards we have come to expect from Alpha Antennas. At present using it indoors experimenting with WSPR and putting it through its paces.

I’ve been using it for a few days on 40m at works well for both phone and FT-8 using only 20 watts. I’ve got no regrets on this purchase.
