Last night we had some thunderstorm activity that was 5 or more miles away
at least. I could visibly and hear static discharging off the reflector to
the boom. The XM240's elements are insulated from ground. I have noticed
this before when the storms are quite distant.
All of the coax and control cables are disconnected and laying on the
ground. I just ran the cables through a buried conduit and have not had a
chance to route the cables back into the shack. Normally the antennas would
be all grounded. Below the 40 is a 4 ele SteppIR with the elements
Anyone else noticed this with this antenna? Is this necessarily a bad
thing? I have not had the radio on 40m while this has been happening I
wonder if these discharges are noticeable in the receiver. The tower is
grounded at each leg with a very minimal radial system attached to the
We have our share of spiders and the birds love the antenna so it could be
possible the arcing is from unknown debris.
