Above right is about 400 feet of tower that had been on site for several years until finally being install shortly before Andrew took the whole thing down. The building to the right houses the channel 6 transmitter.
That’s 1 5/8” transmission line coming off the spool in the photo to the left.
 The winch (top left) has 5,000 feet of 3/8” cable on the drum. The tower is rigged 50 to 100 feet above where the installation will take place to allow head room. In this case the top block (that would be a pulley to land lubbers) was located around 1,300 feet. The end of the winch line is then brought back to ground level and an extra 900 to 1,000 feet of cable is pulled out on the ground. We now have somewhere around 4,000 feet of cable off the drum when you account for where the winch is located. The top end of the transmission line is attached to the winch cable at ground level and the lift is begun. When 200 to 300 feet of line is in the air the winch is halted and the transmission line is again attached to the winch line. A small amount of sag is left it the transmission line so the top attachment point is supporting only the first 200 to 300 feet. The second attachment point carries the next 300 feet and so on so there is never more than 300 feet of line on any one attachment point. When the transmission line is in place it is attached to the tower every 3 to 4 feet.
Below is an old VHF TV antenna lying on its side. It is around 100 feet in length and weighs several tons.
