If it causes a static spark, ie a high voltage discharge, same as brushing ones hair or taking off 2 jumpers/t shirt etc yes. Though the very first radio equipment on boats used a tuned spark, the first sos sent by the titanic used this type of tuned spark, electronic and electrical spark sending apparatus is forbidden world wide because of the interference it causes to any radio wavelength in the spectrum from low freguency right up to microwave 2.4ghz and above.
Very good example though extreme is a lightning discharge the voltage is 225kv, plus there is enough power in a single lightning discharge to run the national grid for 6 months.
Deffo not a good idea for anyone to use r c equipment in a thunderstorm, I won't go into the lightning pilot header that comes first zig zags about dabbing off of trees, metal masts aerials etc when it finds something it likes the main lightning strike will follow and often prefers a lower uhf t v aerial to a much higher in height but lower in frequency vhf radio mast next to it.
