[TowerTalk] Self-supported tower designs

[Al Kozakiewicz]

Straying somewhat afield from the original topic...

G0EVY has a full size 2 element 80m beam (think about that for a minute).  I forget what he said it weighs, but somewhere north of 3000#.

He bought a used truck mounted crane with a 150' boom that the antenna is suspended from.  If you look at his property on Google Earth, it's VERY visible from the satellite picture.

A used boom lift might be a good alternative to building a tower.  I've been tracking the used market and they go for $10k to $15k, used in good condition for 50-60 footers.  (About the installed cost for a 72'  crank
up)  Generally, they can handle 500# loads at full extension at 45 degrees, some are even rated 1000#.  So, my educated guess is a pretty big tribander straight up is no sweat on a few feet of mast.  Of course, it's pretty easy to work on the antenna and bring it down for a storm or hurricane.

Think of the power of the built in rotator!  And they are a lot of fun to run, put antennas in trees, fix your roof, paint the house, etc.

Might also be an answer for hams with tower restrictions - :-) :-) :-)

Wherever there is multistory construction there are a lot of them.  
Several on ebay and craigslist most all the time.
