I'm sure the Amphenol connectors are very high quality and perhaps not as leaky and unreliable as generic (or worn) connectors
The problem with that is that it assumes that the Amphenol connector you properly installed is mated to another Amphenol connector, properly installed.
A few years ago, I added stubs to a couple of antennas for harmonic suppression, carefully placing them for optimum suppression, but didn't hear nearly as much suppression as I thought I should. One of the causes was rectification and re-radiation, as you had posted (thank you VERY much for that), but the other cause was leakage in the cabling that made up my antenna switching, and in the switching itself. Harmonic suppression can be a big deal if you're trying work SO2R on 40/80 and 40/20.
The next summer, I bought a spool of BuryFlex and a bag of 83-1SPs and replaced every piece of coax in that system. I also replaced the 6x2 Array Solutions switch with the newest 4O3A 8x2 switch. Once that work was complete, harmonic suppression provided by the stubs was significantly better, and what I heard was down to the "gurgly" sounding rectification you described.
