Be careful. Some of those telescoping poles have a friction lock to "hold" them up. It doesn't work very well, they will drift down. I know, because I bought one to hold a Ham antenna. I finally had to drill holes in it and go to Tractor Supply for pins long enough to go through it.
There are poles that have positive mechanical latches, but they are a little more expensive. I bought one, then discovered that it is too big and heavy for convenience. It is in the front yard at the S&B now.
I use the military surplus 4 foot mast sections (eBay) for my antenna masts now. the only downside is the area required for the guy wires (dacron ropes, actually).
