Default Horizontal Attic Loop Feed

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



SWR loss is less of a headache with open/ladder line feed.
My principal DX antenna is an 8jk end-fire array cut for 20 meters.
I've fitted it in the attic of all the homes I owned, fed it with
ladder-line, and worked it with a "classic" balanced tuner on 30 through
10 meters. Yes, RF does get into the wiring (especially triggering
slightly opened lamp dimmers), even with good grounding. The array is a
gain antenna, and has given me very good results over the past 35 years
I've operated with this antenna.
