[TVARC] Attic Antenna Advice and Council

[Mark Graybill]

Hi Jeff!

If you avoid running the antenna on the same line as the ducts, you will
avoid interactions. Also, if you cross their path, avoid being close to the
ducts--get a diameter or two of separation if you can, and cross as close
to right angles as possible.

You should still get as good of radiation as can be had from an attic
antenna if you do that.

I will be running an attic antenna under similar circumstances. I plan to
keep it as high up in the rafters as I can, with the feedpoint at or near
the apex.

Mark, W8BIT
