That is neet. Now I just got to figure a choke of RG8X at 146mhz to
keep the RF from comming back down the outside of the coax cable from
the J pole.

My rule of thumb is for RG-213 wrapped around a 4" dia.
2L pop bottle and thus applies mostly to HF. Using a 2"
dia. coil form (pill bottle) with RG8X, my EXCEL
program says 2-3 turns is about right for 2m.

What about ferrite beads/chokes over the coax instead of the coil of
coax cable?

That works. Just make sure the ferrite is functional at
146 MHz, maybe #67 material.
