I think the telescoping mast that I use is one of the greatest "finds" of this entire project. I first tried to find masts or towers designed to go on motor homes. I searched for a long time but couldn't find anything I wanted. On my first attempt, I purchased a military surplus fiberglass mast kit. It consisted of ten four-foot long fiberglass poles, each designed to connect end-to-end with another such pole, a lot of nylon rope to be used as guy ropes, ground screw-in devices used as anchors for the guy ropes, and a canvas bag for holding everything. (A picture of my first attempt is shown to the right.) It is big, bulky, and heavy. It is painted olive drab green, the same as most other military surplus gear. Even worse, I'd consider those guy ropes to be a safety hazard to pedestrians in any campground. It is easy to trip over the ropes and ground anchors, especially in the dark. That is probably acceptable in Afghanistan but not in the typical campground in the U.S. I used it once.
In short, it ws a kludge, completely unacceptable.
