Ahh.
Small lot w/ antenna restrictions here, so my main antenna is a inverted
L < 35ft from my second floor shack. Means that any leakage that can be
detected in the shack with a small loop at 4 feet can be easily heard on
the main antenna.
So, filters and ferrite chokes on everything, LMR240, 400 or 400UF for
everything except a few temp use jumper, and I clear all the seems of
all the gear, check for leaks and even keep a few rolls of conductive
adhesive copper EMI tape around.
Like the be able to run all my gear without hearing it, and figure any
egress is a potential egress. If the antenna 35ft away can hear it,
then 500w transmit on the same antenna is likely to get in and screw
with the gear.
