[Elecraft] OT ... Coax DC isolator

[Barry LaZar]

John,
     Does isolators are called bias-Ts. They are a common way to do what 
you want. You should be able to buy one without great difficulty. Just 
make sure that the one you buy is for the frequency range you plan to 
use it in. MFJ makes one for HF if that is where you plan to operate.
