Re: [TowerTalk] FW: Installing large Yagi

["Tower (K8RI)" <tower@rogerhalstead.com>]

If you have the room at the tower you can try what I did.
I took mine right up the side of the tower, rotating the antenna at each of 
the three sets of guys.
There are two photos about half way down the page at:

It was necessary to rotate the tribander  on both axis to get around the top 
sets.

Once at the top the antenna was clamped to the mast. The maist was then 
raised using a "come along" and clamped in the thrust bearings prior to 
installing the rotor.
The same method was used to raist the 7L 6-meter yagi which has a 28' 10" 
boom.
