The right angle N connector should not be trusted unless it is an Amphenol. Many of the imports have a ball point pen spring inside that does the right angle. Good ones have an actual piece of metal.

This is not the MMCX connectors fault but it is due to the connector being a "right angle" connector. I finally caught on to this when I was testing a right angle barrel N-connector versus a straight barrel N-connector. Anything with a right angled connector was showing a loss of 1-2db. Switched to straight-MMCX connectors and gained a couple db on all links. And this right angled connector loss is present on EVERYTHING from cable TV to VHF/UHF land mobile radio's. I put a right angled F-connector adapter on a cable TV coax once and the TV screen went from clear to fuzzy. I won't use right angle connectors on anything anymore no matter what it is, wireless internet or whatever. Kurt Fankhauser WAVELINC P.O.
