I built the GWEN (Ground Wave Emergency Network - an EMP-proof message system for USAF/SAC) network for RCA/GE in the 1980s and I had a chance to climb a few 300 foot towers. .....
There are not too many really tall towers around here. There are a few 200-300 footers, I've been up a few. This is pretty hilly country, so most towers on mountain tops don't need to be that tall. There are a LOT of little 40-100ft
The KREM channel 2 tower in Spokane is on the order of 8-900 ft, but I've never been up it, and it has an elevator part way up!!
