The reality is this - if a vertical is tilted 45 degrees, then you
experience a 3 dB signal loss off to the sides to a vertical that is truely
vertical. A horizontal antenna can loose over 20 dB when communicating to a
vertical antenna via direct line of site. With skip, it doesn't much matter
as the signals will get twisted around a bit, but for local communication,
figure the cosine of the angle difference. Cosine of 45 degrees is .707.
The cosine of 90 degrees is zero (but there will be some reflected signals
and you will usually get a 20 dB attenuation - a 100 times loss of signal
*both* on transmit and receive). 3 dB isn't huge, but why have a loss both
ways on a circuit?
