We actually just replaced two of them, doing exactly what you describe. There was a catch, though. The feedhorn has two N connectors, a few inches and ninety degrees apart. One of the two dishes had a smaller hole in the center, and my climber had to take up snips and a rasp, and basically put a small notch in the center of the dish, to get the new feedhorn to fit. The other dish was older, or newer, or something, and already had a suitable small notch in the center. David Smith MVN.net
