I posted this on the wrong newsgroup a few days ago and no one has answered,
so I'll try here.

I have a Butternut Vertical (as a secondary antenna) and a regular radial
system set up with it. I also have a metal roof on my house (here in the
country in Western Washington). I have been wondering if I can use the
metal roof as the radial system/ground plane for this antenna. Haven't
tried it yet. Would this work or would it detune the antenna?

What do you guys think?

Rod,

Several years ago I tried a 14AVQ vert next to the house with a big
jumper to the tin roof. Boy was that a mistake! It did not work at
all. I gave up on the vert and installed a tower and beam.

FYI, the best improvement ever made to the beam was when we replaced
the tin roof with normal singles. It was like getting a new antenna too.

Good luck with the tin roof. BTW, it did work pretty good with a mag
mount VHF/UHF antenna. HiHi
