Hi Steve and all,
The Rohn BX was also used as part of the Hy-Gain 18-HT HY-Tower 80-10
Worked great for that. I have to agree about your comments about climbing
one. Only had to one time and that was enough.
Also have read that people have taken a BX to be re-galvanized. Supposedly
the rivets used on them are aluminum and met when hitting the hot
galvanizing they met and the tower is now in kit form. I cannot confirm
that. Don't want to find out the hard way.
