I'm in a valley here. I would need a 400 footer just to get up to where I could see line of sight.

Yeah... I like that he put up two 300 footers 'as an experiment'!

When I win the lottery, I intend to put up a 400 footer for my repeaters
and a couple of 120 footers for the shack.

Guess I should buy a ticket once in a while.
