Hello.
A while ago I tested the MEF-1 but had some trouble adjusting the SWR. The problem was actually due to my MR-100 antenna analyzer. I tried again and this time got a perfect SWR, from 1.1:1 on 14MHz to 2:1 on 14.35MHz. That's a lot of bandwidth. My wire is 33ft long, or 10.1m. The Reverse Beacon Network report was quite surprising with quite a few spots from the United States! Now I need one for a 30m end-fed.

I used the Ilertenna for 40m and 20m with good results.
However for 30m the Ilertenna doesn't work fine and I use the Mountain tuner of Sotabeams.
I am waiting for. Shark 100 analizer from China...

Hello Jon,
Did you try it with different lengths of coax or a counterpoise? What was your wire length?
I haven't ordered yet, out of money, but it's next on my list...

For 30m I use a radiator length of 14.23m and a counterpoise 4.74m.
Almost I used the recomended for Javier Solans from EA3GKY kits and the same.
The coaxial is a lead of RG-174, tested and working fine.
This week I made a picobalun from Sotabeams todo make a ultralight 30m dipole (winner Horse).
