Installing Large Yagi Antennas

First we had to remove all the old antennas from the existing 165 foot Rohn 55G tower:

Justin and W8JI Tom at top

We then added 3 sections of tower, a new guy ring, and a new layer of guy lines. The first antenna up was a full size 40 meter Yagi. This is a homemade cradle that rides up on a temporary steel tram line. It holds the antennas flat and stable while being pulled into position:

Then we pull the antenna up:
