Marc, My Cushcraft 402CD seems to load on 160 meters through a tuner. Its almost as good as my L or Multee on transmit. It is up 86.5 feet. What I assume is that the coax is loading and the 402CD is

Ed, The Uni-Hat vertical is a very effective vertical for 160 and 80 (I never tried it on 40 as I have the 2 el 40 and its a killer at just below 90'). The problems lie in trying to put down radials
