What is the recommended way of fixing two antenna mast sections together? The mast I bought doesn't fit snugly together and will need to be clamped (preferred), bolted, or welded together. I seem to remember seeing a band and bolt type clamp on mast in the past, but cant seem to locate any. I can use u-bolt clamps, but would like to use something a little less noticeable. I dont think bolting will make it very secure unless I slip something into the mast to drill through and tighten down on. This is a ground up installation with the first wall clamp up about 12' so I'm going to need all the rigidity I can get. Thanks!!!
