Set up on my ten story terrace. Pulling in all kinds of stations on all the bands. Very happy with the performance of my Mag Loop. Well made should last for years.
If you’re not looking at a mag loop antenna you need to look again. Alfa Antenna has the best mag loop antennas on the market!
GREAT Product works even better than advertised! I will be purchasing the 80 meter add-on soon! 73 – Shane Jackson
Worked all the bands with ease, excellent results.
I purchased the Alpha Magnetic Loop Antenna along with the heavy-duty tripod a couple of months ago. It was straightforward to set up and get running with my radio. Tuning the antenna can take a little time because the tuning knob for the capacitor is very sensitive, but I’ve never had a problem achieving good tuning when using my antenna analyzer.
I’ve been very pleased with the performance of the antenna. I’ve set it up various locations indoors around my house, and I’ve been surprised at how well it performs. Using just 20 watts on FT-8 I’ve made hundreds of QSOs since getting it, including contacts to the Kiribati Dxpedition T32TT on 3 different bands, a distance of over 7100 km from my location in Texas.
I did have a problem early on with the 3D printed parts that have female 3/8 24 threads. I found them to be extremely fragile and they stripped out far too easily. However Steven, the founder of the company, met the challenge head-on and sent me new upgraded parts to take care of the problem. I’ve been very impressed with his commitment to customer service.
I can highly recommend the Alpha Magnetic Loop antenna, particularly for those users that need to have an antenna in a very small space indoors. Also Alpha is a great company that will work hard to make sure you’re happy with your purchase. You can’t go wrong with this company.
