Dry blowing snow or high wind can cause quite some voltage build up on a
antenna, especially a long one. It is possible to draw quite an arc to ground.
There have been reports of high voltage electrocutions from antenna static
build up in Short Wave Broadcast stations. A short stick was mandatory for
maintenance periods.
And yes, I did work at a shortwave station with 500 KW transmitter output.
So receiving antenna wire insulation could have some benefit if the voltage on
a bare wire is leaking to a tree limb or across an insulator. Beyond some point
all insulators can fail.
Indoor antennas do hear static, but I have never seen any evidence of voltage
build up. ( The building may provide adequate insulation.)
Out of curiosity, has anyone ever really done testing of voltage buildup on a
insulated antenna wire, VS a non-insulated wire ?
Indoor antennas VS outdoor antennas of equal size?
