Hi,


Just added some more, and hopefully, explaining pictures.

I connected them to a ~400 feet hardline. Tested the SWR. It was 1.5/1 with a 
75 ohm termination up to about 65 MHz. There it increased to 1.6/1. I don't 
know if I measured it right but it appeared as I had  1.2 dB attenuation over 
the 400 feet at 65 MHz. (Is that reasonable?)


I don't think my contraption will add anything to the SWR. I tested a very 
short piece and found the same behavior. As the center conductor is passing 
through the connection in a similar manner as it is in the cable itself I don't 
expect any surprises. The PL-259 connector is what it is so I can't do anything 
there.
