Hi. If I want to talk abrefoot and run a dipole for 27 MHz in my attic, I
noticed there are numerous versions. The vertical is out for obvious reasons. So
there are inverted and horizontal. Is there any version I am better off using
barefoot?

Barefoot or not, an attic is probably the worst place to put an
antenna. You have all kinds of possible problems, not the least of
which is house wiring or foil-backed insulation that can cause
reflections (high SWR).

Only one AC romex wire going thru. No foil on insulation. Standard rafter and
plywood sheating.

There is also the issue of polarity. Almost all mobile CB antennas are
vertical so don't expect strong signals from a horizontal antenna, or
even an inverted-V which is largely horizontal. You might get some
skip but that depends a lot on the position of the antenna -- you
might have to rotate your house to align yourself with the traffic.

I would think your best solution is to buy a cheap antenna tuner and
load up the flag pole, rain gutter, drip-strip, sewer vent, aluminum
siding, chain-link fence, steel shed..... whatever works best.



I am going to have to think about this. I really wanted a temporary solution
until I can hand one on the tree.
