static high voltages of antenna protect
 
i have an inverted L antenna for medium waves. i would like to ground the static high voltages. the antenna has static high voltages when the weather is not good.
i am looking for a easy system to ground this voltages and to protect my transmitter and the tuning circuit.
i had seen a schematic with carbon resistance about 10kohm which is connected between the antenna and ground. this solution is ok? do you have to propose any idea?

Yes, fine as long as you don't connect it somewhere where the system
impedance is high (like the end of the radiator!). Surprising you should
ask something so basic when you claim to run an engineering 'corporation'

Doing so would act as a static drain, but may not be effective at
preventing damage to whatever your antenna is connected to if there
should be a nearby lightning strike.

A better approach for that might be to disconnect the antenna from
your equipment during lightning conditions, and connect it a good, low-
Z, earth ground.
