I purchased the Alpha Antenna Alpha Loop Jr+ Mag Loop from Tom, KA3TKW. It’s built of a tuner box, loops of LMR400, and a tripod, and tunes 40m-10m.
Tuning is pretty cool with the geared box, but still pretty touchy. Tuning is very necessary: a band will be completely quiet until tuned, and then noise and signal really increases. I tried it inside, and it didn’t work so well: lots of inside RFI.
Outside, it worked much better, but the 80M EFHW is still better: higher, and broader bandwidth.
The directionality and tuning is neat I can wiggle the spacing of the inner loop to the outer loop to “adjust” induction / SWR. The high Q means efficiency, but I need to re-tune the capacitor any time I move around the band.
