Grant, tnx also to you.
I think you highlight the very critical point; electrical connectivity
along panels is likely to change along time and could randomly impact the
pattern/SWR of nearby antennas.
I think I will opt for a neutral (no aluminium) roof: I'll miss a good
ground for a roof mounted v
Jim, tnx for sharing your direct experience.

I had a 40m and 80m top loaded vertical on galvanized steel roofs. The
80m was outstanding for DX and the 40m so-so since the roof was not well
bonded electrically. IMO, unless you can insure electrical connectivity
along the panel seams there will be no advantage to the foil. You would

Last year we replaced the 20+ year old roof on our house. It was made of
treated cedar "shake boards", with simple tar paper and plywood underneath. My
antennas consist of (1) 26.8 meter long doublet fed with 450 ohm ladder line,
(2) 80 meter Inverted L, (3) 160 meter Inverted L, (4) 5/4
Hi all,
tomorrow I must decide which type of insulating system to be used under the
tiles of my new roof. Roof's structure is classic wooden and total surface
is 220 square meters.
Since there will be several antennas for 80 / 160 sorrounding the house I
am wondering if using insulating panels (pol
