My guess is also the steel wires, which have very poor conductivity at
HF compared to copper. Aluminum fence wire is also not a good choice
and would likely literally dissolve if buried, depending on soil
characteristics. I use army surface field phone wire, which is a mix of
copper and steel strands, both wires in parallel for each radial. The
insulation makes zero electrical difference with buried radials but
should preserve the wire for many years. About $60.00 for 2km on Ebay
including shipping.

Hi guys,
I've had two or three different hy-towers in my time and I don't recall any of
them having this high of SWR on 80/75 mtrs at resonant. Maybe it is the
galvanized radials from the local farm store (Wilco)?
