Re: [IRCA] Cable connectors

I liked your explanation except for the part below. Considering the choke impedance to be part of a voltage divider along with the ground resistance, you surely need a choke with at least several thousand Ohms of impedance. With a poor ground connection (sandy soil), you can need even more. I won't bore everyone with the explanation. 
 
Bottom line: I don't think you can ever get even close to that with the over-the-cable chokes. I can recommend only the chokes made with mini-coax and high permeability (at least 2000) material.
