[TowerTalk] MA-550 Installation

[JOHN OWENS]

Mike:

I installed a UST 72ft motorized tower in 2004. I believe the base was supposed to be 4x4x8ft. I had a friend use a back hoe to dig the hole. With a back hoe, the hole is going to be larger that the targeted size, because it is not precise. My hole probably ended up being closer to 5x5x10ft. Not to worry. All worked out fine. Big heavy duty rebar cage in the hole, and then fill it with concrete and finish it off. 

I tend to be risk averse so I lower the tower during higher winds. Tower was used and is now probably about 25YO. All is good so far.
