Hi Pete,
As long as your relays have decent isolation, even for high impedances,
it may even be better to switch the Bev wires themselves. That way you
don't share the ground at the feed end, and avoid any common impedance
coupling.

Jeff, I suspect that you mean modern day synthesisers rather than
specifically DDS. Actually, the DDS itself has quite low phase noise,
better than -130 dBc/Hz with Analog Devices chips, especially if the

Not only does the antenna add good top loading, but it is quite neat to
be able to tune the match to different parts of 160, simply by changing

Hi Ashraf,
The rule of thumb I use is 2D^2 /lambda, where D is the largest
dimension of the antenna. So if your Bev is 320m long you need to be
over a km away. If only 160m long you need to be 300 m away.
