[MRCA] UG-565 adapters

[Ray Fantini]

It dose change the length but as long as you are using identical length adapters on each line so what? The trick is to have everything equal on both stacks so long as you mateine equal delay everything will be in phase. It’s all easy with HF, gets hairy at VHF and UHF. Played around enough with AM Broadcast transmitters where you were able to have maybe a inch or so difference in the amplifier to combiner and did not see any difference.

Doesnt adding the C to N adapter change the length of the phase line?

Why do UG-565 Type C to Type N adapters cost so much! The final output combiner on my Harris RF-1110B uses them on its input and the output of the rack frame are all type N plugs. Been using just one half of the amplifier, two panels and that comes out as a signal N connector on the back of the amplifier frame. But now that I am getting the other half of the amplifier up and running will need to connect the original external RF combiner network external of the amplifier and that has type C connectors. Don’t know what I did with the original cables but will have to have matching cables from each set of amplifiers and matching adapters to keep everything in phase. Have a couple adapters now for the output and rejection load.

Looked on eBay and it looks like they beat you down for at least twenty or thirty bucks per adapter! Plus shipping. Maybe I can con someone around here for less?

Wonder who’s idea it was to use C connectors anyway?
