3 kwi 2019 · Using the keypad it is possible to enter frequencies and the loop will auto tune. But there is a problem. When testing the auto tune on the frequency range in steps from 7000khz through to 28000khz there is an intermittent fault.
No complaints! Time Owned: more than 12 months. I bought this as a used unit ten years ago. It is in daily use, mainly with a G5RV set up as a doublet, occasionally on a 20 - 10 metre OCF dipole and a long wire, and it tunes to 1:1 on all bands, 160 metres* to 10 metres.

This can detract from trust by current and potential customers. eHam considers soliciting and/or rewarding favorable reviews by manufacturers/dealers as unethical and unwelcome.
The MFJ-935 is a specialised Loop Antenna ATU for portable/home station use. It has a built-in RF antenna current ammeter for tuning. It turns virtually any wire loop into a high efficiency transmitting loop antenna.
29 gru 2019 · Hi Everyone, I posted my review of the Ciro Mazzoni Stealth Loop. Overall, I am very pleased with its ease of use and performance. I am in a very restricted HOA, and this loop is less visible than other designs, and it tunes automatically.
26 sty 2021 · You'll have to re-tune if you change frequency even slightly. I've built a couple large diameter tubing loops and found they worked better than I expected. However if you can't mount it in an area free from metallic objects (at least 15ft?) the performance will suffer.
You may have heard all sorts of stories about the use of electrically small tuned loop antennae on HF, many of them erroneous. This essay plans to set the record straight, and also to describe a very effective portable antenna for 80, 60 and 40 metres which any ham can build.
