Hi,
I have a few bulkhead feed-through adapters (UG-363 type from Universal-Radio) that are SO-259 at both ends and they are TIGHT! I can barely force in a PL-259 and then when I try to remove it the center pin and insulator get pulled out and the cable is ruined. I have tried more than a few cables on these feed-throughs and they are all tight. I don't see that I'm doing anything wrong, but I may be missing something since I have three of these things and they are all the same. IS there some kind of lube that should be used? Are they all defective? My cables fit fine in all of my radios, SWR bridges, etc., but they don't fit in these feed-throughs.
ETA: it appears that I was wrong on the other two feed-throughs. They do seem to fit my cables properly so I only have one that is out of spec. I'd like to fix it if possible and they only way I can think of to do that is to ream the inside out and I doubt that will be successful without messing up the contacts since it is kind of a collet going on in there.
If anyone has any ideas how to open this thing up just slightly I'd like to fix it instead of junking it. Maybe some fine grit sand paper in a roll?
Thanks,
SOPMOD
