*_/THIS is a KEY point/_* to pay attention to, even more with what Jack 
just told you.  If two KAT500 are telling you the same thing; that's the 
clue.

One weak point at ANY area of the antenna SYSTEM; once it fails, you 
will get an intermittent until it's permanent.

System:  EVERYTHING beyond the SO-239 connector at the KAT500. 
Connector, coax, patch cables, adapters, ALL the way to the antenna then 
the antenna itself.

It's a reasonable expectation that your issue is NOT in the tuner, since 
both tell you the same thing.

Good hunting!  73,

PS the G5RV antenna was designed to be a SINGLE band antenna, even it it 
loads on other bands.  You WILL get a reactive response on other bands.
