Hi Jason,

I used a vertical mast mounted here for the last five years and it works
fine, the one thing to take into consideration is almost every backyard
style installation on HF is a compromise even if you get everything right
the neighbours stereo /computer speakers will bounce off the wall and this
is part of the fun (?) of amateur radio i.e. getting it working. My old
house had iron roofing and it was great with a butternut HF 6 v I worked
DXCC easily without a beam antenna. I recently bought a VK version of the
Butternut and it will go up in a similar location: on top of the shed. 
Using the compromise style of antenna for some time I like the idea of the
rabbit wire under the tiles, so I'm off today to buy some. Thanks for the
idea !

Greetings Everyone-

I would like to set up a vertical antenna at my QTH, but my small backyard
is arranged such that it is impossible to set up a good radial system. In
addition, my house is right in the middle of the yard, so the best place to
put the antenna would be on my roof.
Rather than running radial wires all over my roof, I was wondering if anyone
on the list has tried making a counterpoise system by placing wire mesh
(such as rabbit wire) on the underside of the roof in the attic? I have easy
access to the underside of the roof, so the mesh could be stapled (using
short staples, of course) right to the roof sheathing underside. The pieces
of mesh would all be tied together to create a large counterpoise.
I have not been able to find much information about the effectiveness of
such a counterpoise in the Antenna book, or from other source, so I would
welcome anyones experience or advice.
