I got a 35 foot mast that I was gonna hang that and some VHF UHF and a perhaps a tunable loop off of, but I have never had time to sink the thing into the ground.
I have thought about getting one of the MFJ loop tuners to play around with. Of course you can put a loop close to the ground. The EF 40 is a good antenna. Though they don’t hold up under a lot of transmit power, a matching unit can be built which will handle more.
