Just a short note on real life A-B.
I have two identical 80m Inverted V Dipoles. Both with 45 feet high apex.
One above the roof of the countryside house with some 60 feet of feedline
and the other about 400 feet away from the house in the dense forest with
apex tied to a pine tree.
Guess with one plays better! No question about it - the one in the forest
with 6 times longer feedline.
It is constantly about 1 S-unit stronger on TX and RX. It has absolutely
noise from appliances in the house unlike the other one.
The forest consists of pines, birches, firs, alders. About 50 feet high
average level.
The house and the vicinity of it with its man made structures seem to do
much more harm to the signal than forest.
