[QUOTE="RimaNTSS, post: 1140875, member: 312276"] Well, I was asked whether it is possible to install multifeed on Channel Master antenna but on original feedarms. Of course, there is original Channel Master multifeed system optionally available. [ATTACH]146775[/ATTACH] But, TBH, I do not think it is a good solution, it does not allow installing a central LNB in the focal point of the dish, it will stay too much outside the proper location.

The easiest way would be just to stick a piece of wood in the pipe and then use a simple wood screw to attach anything to it. But that would be to easy.... So, I made a conical nut and an insert made of Teflon. When the nut is tightened, the insert expands and sticks very firmly in the tube.
