[TowerTalk] how long could be the mast ???

[Douglas Ruz (CO8DM)]

Hi,

I am planning install an small tower for small yagis fixed to EU.

I have only 2 tower sections (10 ft each) and a 18 ft mast (galvanized water 
pipe 1 1/4 or 1 1/2 " and 1/4 inch wall) for that project...how long could 
be the mast ???...14 ft??...12 ft ???...

I would like install a 2 elem homebrew 20m yagi on top of the mast and 3 
elem homebrew 15m yagi below and maybe 4 elem 10m yagi attach to the top of 
the tower (not in the mast)....so, the mast will support 2 antennas...the 
tower has one set of guys near the top.

any idea???

Thanks,
