If you have 8 or 10ft of extra feedline you can just wrap that around the core. It would be great to see what your noise floor is across the HF band before and after the choke in installed.

The coax I use for everything is JSC wire & cable mini 8/u .... I probably have close to 500 feet of that here on a spool that was leftover from my cb days back in early 90's ( JSC Wire and Cable | Copper Electronics ) everyone use to call it the"good grey stuff". I'll try to wrap it on the feed line first if my feed line isn't too big in diameter ...I know u suggested rg58 and I don't know if that's smaller than my 8/u or not but we will see

@prcguy ....got the toroid in today...I'll have to make a box and do it that way because I really don't have enough slack in the coax to do it direct....is this how it should be wrapped??? The bigger gray coax is a little hard to work with so I may get rg 58 and try it
