Indeed, I forgot about coiling up the coax, I´ve
used it many times, workes great.
Same here, no stores for UNUN, baluns and gizmo
stuff, however I have a lot of 50 ohm coax, besides
UNUN´s and Balun´s tend sometimes to send out
smoke signals.
The simpler the construction is to more reliable
it will be over time.

I stacked about 10 torroids directly below the feed point of my wire

I can't have a heavy coax coil balun directly under my elevated the feed

the coax around a 3.5" dia 12" former at the point the feeder enters the
shack - Viola......it cured all my RFI problems. The former was the largest
dia container I found and stole from the XYL's kitchen!
I am certain that larger dia PVC pipe would be more effective.
One needs to improvise when you live in a place like Jamaica! No stores for
UNUNS, Baluns etc! In fact, I can hardly find 50 ohm coax here!
