Looks like I'll have to use a horizontal loop in the attic for a few
months.
Any opinions on how to best feed it?
--open wire
--coax coil balun
--ferrite bead balun
--straight coax
The loop is about 13 feet per side, and I want to operate 20 meters and
up.
In the past I have simply used a coax feed without a balun. It worked
OK,
but there was a lot of stray RF around the house.
TIA
Another option is the one that I use which is a fan dipole - it
would be simple for 20 metres up - mine is from 80m up. It's fed by
co-ax via a balun. You can see details at
http://www.radiowymsey.org/FanDipole/fandiploe.htm . The only
interference I have had was to my son's amplified computer speakers
which was easily cured by winding it's input lead on a piece of
ferrite road. If you checkout the slinky dipole page you will see
how easy it is to make co-ax balun.
