M0KHRTrying to see how I can get a usable 7, 3.5 or 1.8MHz antenna.
Now having found the LC metere, re-checked the pot I have done in the past, and the max microH I can get out is just about right(ish) for 3.8MHz.
.. but... I don't have a 4m ceiling here to have it inside, and to have it outside is a LOT of work. Outside is obvs better.
erick@M0KHR I have a large square loop going around garden for 6-80M. For 160M I build the https://www.k6mm.com/pages/160M.html K6MM "no excuse" antenna. It actually works. Very much compromised but works. I was lucky I had fibreglass military mast material. I used cheap wire for wrapping. Will prob put it up again soon as winter approaching.
