Hi guys .I am just wanted to confirm a question on coax shielding .
With 2-10 watts transmitting through rg213u  could rf be escaping that could
cause desensitization  to other radios .The repeater I have setup uses 9
meters of heliax from the main diplexer to ant  and rg213u from the link
radio to its antenna  .
I am finding I am getting problems with the link transmission interfering
with the  repeater rx The link antenna is a yagi 3 meters above the ground
and the main repeater antenna is 6 meters above it .I am currently trying
band pass cavity on the receiver rx or band pass/band reject diplexer with
some success but I am wondering if the rf escaping from the cable is causing
problems inside the repeater shed even at a low wattage .I am definitely
changing the rg213u to either rg223u or lmr400 as it is only on the link
radio and shouldn't have any effect on the repeater's operation .Has anyone
else had the same sort of problem where the rf energy leaks out of the cable
in the shed and causes problems to the repeater and they had to upgrade the
link cable to 100% coverage cable
