[50mhz] cushcraft question

[Greenacres113 at aol.com]

i'm considering the Cushcraft  3 el.
 
i've had two of their 11 el. 2 mtr fm antennas. both my dads  & mine suffered 
coax connector seizure after a few yrs.  you can't get  the pl259 off any 
way. i cut the coax & fabricated a new plate with a new  s0239. it was the only 
easy answer. i wonder if using 'no alox' or the common  electricians metal 
conduit helper will prevent the seizure.
 
i've not had this problem on other antennas
