20 Feet of RG174 vs 20' of CAT 5 Cable
(A back to back insertion loss test)
So my debate about RG174 as a viable TL for my portable 20/15m sloper came to a screeching halt when compared to my CAT5 TL.
I set up the KX3 with my 112 ohm baluns and measured the matched insertion loss.
First performing the CAL THRU measurement in the back to back mode. (The Red to Black convention is actually phased correctly. One balun is wired backwards).
Then I stuck the CAT5 in there. The CAT 5 suspended on plastic camp tables 18” up off the floor. And of course I can't get the photo rotated correctly...
