Safe removal of a ~30' HAM Radio Antenna
I have a friend who has a 30 foot (approx) HAM Radio antenna mounted on his garage. The pole base attaches to two brackets which are anchored to the exterior wall of a garage. Near the top of the antenna, 3 cable anchors connect to brackets on the roof. He wants it gone, and wants me to take it. But, this must be planned out carefully. The pole could be lowered 3 feet or so, so it makes contact with the ground. It could be used as the fulcrum to lower this down into his backyard. Power lines are not in proximity. If several people were on the roof, could that point be used to lower the antenna gently to people on the ground? My concern is that the construction looks aluminum. The pole is 2" steel pipe. ButI cannot be certain on the actual antennd contruction or weight. There are 3 or 4 small boxes mounted at various heights on the pole. I can't image they weigh too much. Can anoyone tell me what there are used for? Occasionally, a red led will blink on the bottom of the case.
I am excited to acquire components that one day may help me get my amateur license. But I am concerned about how to safely do this, and will not attempt without a very clear plan. I don't want it to end up being too heavy, and slingshotting the people on the roof (like something that would happen to red green). I also need to insure his roof is not damaged. I think the brackets will be left on, and the cable cut at the base.
Any knowledge is greatly appreciated!
