30' tower .... and I was (also) trying not to make it less than 30 ft by dropping it too far in the ground. Don't know the make ... it was used - well used - and doesn't have any markings on it. It's rather compact compared to what I used in the past for a Moonraker (last time I used a tower - 25 years ago) ... triangular with about 15" sides. Straight with only about 3 feet at the top narrowing to a point.
Where I'd planned to put it, it would be attached to the deck at 5' and to the house at about 18-20'.
Since I'm in the country ... I'm on a well and that's why I'm afraid of running afoul of the water line to the barn. I know where it exits the house and the chances are 50/50 that it runs inside the "envelope" of safety .... and I'm assuming they put the power in the same trench ...
"All" that will be on the tower is the deep finge antenna with a rotator, as well as (lower down) my Davis weather station that's still (after a year) sitting all boxed up. Anemometer and rainfall gauge.
