As I've stated before, What does Jim Miller of Comtek Systems say?
Contact him; he and I discussed my near-in fence prior to me
constructing my 4 sq last year. I just grounded it in a few places and
made sure that it was contiguous (is that the right word?) along its
length. Works like a champ. Phil KB9CRY
Of course the fence is interacting with the array. I'd think you'd have
to make it invisible by detuning it like you'd detune a resonant tower
that is close by.
