I just wanted to check this with those with practical experience.
If you have a few flags in a few directions and want to build a
switch, how much attenuation between ports do you need?
I'm thinking as little as 30dB would put even strong signals picked up
by an opposite direction flag down in the noise of the desired
antenna... but in practice, might I need more?
Building a switch is easy but building a high isolation one is maybe a
little more difficult, and I should probably go into it with an idea
of how much isolation I need.
(By the way, I know I could just build a rotatable flag, and used one
last year, but I can use bigger ones more conveniently if I go with
fixed-direction antennas)
73,
Dan
