[TowerTalk] N connector, Re: UHF (PL259) soldered center

[Steve Maki]

Not really, they're both rated for -165 dBc, or something like that.

BUT, the 4.3-10 IS supposedly less dependent on accurate tightening with 
a torque wrench (during mating with the female connector) to achieve 
rated PIM results than the 7-16.

At this point in time I've done thousands of PIM tests on 7-16 based 
transmission systems and have not found a big issue with inaccurate 
torquing of the connector in the mating process, as long as it's been 
tightened....well, good & tight. Problems are usually related to 
improper installation of the connector onto the cable itself. Center 
conductor too short, shield too short, improper coring, metal debris 
left behind, etc.

Surprisingly, some of the worst problems have been with certain runs of 
factory made jumpers, the manufacturer to remain nameless.
