[TowerTalk] Mounting Yagi on the side of the Trylon tower.

[Alex Filippov]

I am looking for antenna and installation advice.

I am looking to install a tri-bander 10-15-20 on the side of the
self-supporting 80 ft Trylon tower at around 35 ft above ground level to
stack with the tri-bander at the top of the tower. I really would like this
antenna to rotate maximally around the tower. Obviously, there is a limit
to how much it can be turned. The distance between the center ( driven?)
element of the tri-bander and the next element should be maximally possible
to accommodate the max rotating angle. Also is the length of the arm on
which the antenna will be installed.

I am looking for practical advice on the best suitable commercially
available tri-banders for such application and any advice on the
installation. It looks like it will need two horizontal arms, rotator
plate(s)

I'm sure this has been done many times before, so if you know where to look
for advice to avoid the errors of the first time tinkerer, that would be
greatly appreciated.

Thank you,

Alex, WK1O
