[Elecraft] EFHW

[Fred Jensen]

George, KJ6VU, is a principle in the Pack-Tenna venture and a good 
friend.  I don't have one but I've seen it.  It's a fairly slick package 
for field work and it does not need an ATU which might put another 0.1 
watt into the radiation resistance instead of heat in the ATU.
