[TowerTalk] Cut off extra 7 ft of mast or leave it?

[Gary Schafer]

I don't think that I would put a 20 foot mast on top of a crank up tower!
What type of mast do you plan to use? Aluminum, Molly etc?

I have that same tower and it would worry me with that high of a mast especially when tilting it over. A lot of stress there.
