Clint,
Why settle for a loaded vertical if you are in the country? You are only
talking another ~20' of height for a full sized 1/4 wave antenna. If you do
proceed with this design, consider doubling up the tubing at the top of the
vertical where it is drilled for the tophat. Also consider something more
electrically and mechanically sound than just putting hose clamps on the tophat
elements to hold them in place. Over time, wind induced vibrations may widen
the holes through which the tophat passes, leading to failure either
mechanically or electrically- in this case giving you an intermittantly non
resonant antenna. As for base loading with a coil, consider multiple taps
switched in and out to give you the bandwidth you desire.
