[RFI] Fence wire material advice

[Juan EA5RS]

I am going to install a 2m high metal fence around the area (20m by 20m)
containing shack building and initial towers in our new contest station
where we will operate M/S, so must be able to hear well on different bands
while TXing a full KW on another band.

 

I might also try the fence itself as part of the ground/counterpoise system
for the verticals to be installed there.

 

Looking for advice on whether it is best to go for bare metal fence wire or
insulated metal wire in terms of RFI and ground system performance for
verticals, as insulated wire is more expensive

 

Thanks in advance,
