hi


a friend of mine might get permission to put up an antenna or two on top
of his apt building about 30 stories up mostly flat roof

the other buildings for a good distance are less than 6 stories

so i was wondering how do you protect something like that from
lightning

even if he disconnects the rig from the antenna you've still got well
over 100ft of coax with a lot of charge


there are no other antennas up there just a red flashing light ontop
of the elevator room

what is typically done?

running a heavy cable to ground downside the buidling is out

i guess it wouldn't be 'code' to grab a electrical ground out of the
elevator room, and i guess equally bad to tie into the steal girders
in there

so how do the pro's do it

The building has no lightning protection in place now?
