Topband: active antenna height

[Richard (Rick) Karlquist]

Increasing the height by 10% or so is worth a dB or so in
signal level (not S/N ratio).  You didn't say if you are
already planning on top loading wires.  Adding those will
make a lot more difference than an extra 10% height.
If your antennas are guyed, the loading wires are "free".
