AM antenna grounding
So let's say there is no AM tower somewhere, and it's a big lie that it's not in use, and the feeders are totally not missing. Anyways, the static potential on this non-existent tower is still somewhat high and if one were to touch it while standing on the ground, the result will be a bit shockingSmile Question is, if one day it was discovered that somebody(this is just plain sailing here) short circuited the lightning discharger, basically grounding the tower(AM towers stand on insulators, in case captain ain't hereTongue), what would the short and long term effects be? It's my understanding that somebody might want to do it to not have to bring a wooden ladder every time.
Here is a picture that is completely unrelatedWink

Re: [REDAKTOR] AM antenna grounding
If the tower was in use, the earthing of the tower would be noticed as the strength of the AM signal would fall dramatically. If the tower was not in use, no one would notice and getting on and off would be easy as all static and residual would be discharged as the tower is at the same potential as the ground the jumper is stood on, provided the earth impedance is low enough. If there are resistors in line with the earth they would need to be shorted out too.

The same effect might be accomplished without needing to be so close to the potential spark/arc. A heavy gauge non-insulated wire can be anchored to the ground nearby with a large spike and the opposite end enough slack to allow throwing at/through the tower - you're far enough away any arcs don't have a chance of hitting you and ensure more complete and sustained grounding. Once the wire is hanging on the structure and no sparks are seen, you know you're okay to touch.

High pressure urine stream works too.

Only if you're close enough.
