Thanks for the ideas and discussion guys. Food for thought.
Can anyone address the 2 points I asked about?
Rohn vs Glenn Martin bearings:
http://www.texastowers.com/rohn_tb.htm
http://www.glenmartin.com/catalog/page195.html
Is a Rohn rotor shelf beefy enough for the bearings?
New question:
How about aluminum masts?
http://www.heightstowers.com/accessories.htm
They also have bearings which look like the same ones at Martin. Any
experience here?
