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

If the antenna is in the attic you are going to have RF in the house
because the antenna is IN the house.

I wouldn't expect otherwise. It was just a comment about what was
previously observed. In fact, the RF got into the computerized thermostat
and burned out the computer. The new thermostat has ferrite chokes on the
leads, and it has survived nicely.
