[TowerTalk] Push Up Al Mast

[Jim Brown]

Here's my response to a similar post on the NCCC reflector last week.  
May not help Maximo, but a great solution for hams in NA. Glen and I 
heard about the idea from K7JA as part of talk he gave several years ago.

The mast is built from 4-ft sections of surplus Al mast sections, and a 
tripod adapter that W6GJB found at Dayton several years ago. Two 
sections in each leg of the tripod puts it about 5.5 ft above ground, so 
sections can be pushed up through the tripod.

Here's a source of the sections. google will find more. The company also 
sells guy rings.

Here's the tripod adapter we use. They also sell the mast sections, guy 
rings and other accessories. The SMOOTH aluminum sections are the ones 
that work with this setup.

W6GJB found a slick aircraft tie-down anchor that can be driven into the 
ground almost anywhere. http://www.flyties.com/images/flytiespack.jpg

The antenna rope that HRO sells works fine for guying. You'll probably 
want to rig a marine pulley for the rope to the antenna.

We've used one of these masts to hold the center of an inverted Vee, but 
properly guyed, two of them could also hold a flat dipole.
