I used old RG8 Coax shield - removed from the coax of course. Solder lugs on
each end, and some heat shrink to keep it pretty. That will probably help with
Kurt’s wire fraying issue too.
One odd thing, K0BG discounts the idea of much RFI coming from injectors. Good
site though.
I’m going to look at putting some coax shield over the injector wires, and
ground at both ends. Maybe that will help my problem.
