I guess the price is high because they are not commonly used.
 
Personally I like C connectors. They are bayonet which is a simple install and removal. They make a firm connection so they take vibration and have a large center pin.
 
They are used of the Honeywell HF couplers I have that were used to feed the tail antenna in the KC-135.

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?
