If you can't put up a full size 4 square array with at least 5 miles of
radial field - you are wasting your time and any one else that will have to
try and hear your puny signal. It is a waste of money and time to put up
anything less.

Why not just find a used HyGain Hytower and put that up? I have been using
a homebrew version of it for the last 4 years and it really works fine. you
get 80/40 and 20 with no coils and it is 53' tall, requiring one yard of
concrete.
