YES! Only first quality connectors and adapters should be used.

I run legal limit to resonant antennas fed with 50 ohm and 75 ohm coax 
and hard line. Amphenol 83-1SP connectors are the standard throughout my 
station. I use type N only on hard line for which UHF connectors are not 
available. I've NEVER experienced any symptoms of arcing in connectors.

I HAVE seen lots problems caused by poor quality connectors and 
adapters, and by poorly soldered coax connectors when putting stations 
together for Field Day and similar operations.

My rule: In North America, if the connector doesn't say Amphenol 83-1SP 
or have a MIL spec number stamped on it, it is JUNK. The same holds true 
for adapters.
