I think i will just make my own. Looks like thats what everyone else does. I am not payin 10-20 for a piece of plastic.
I made one out of a small length of 2x4 using a circle cutter to cut out the circle for the throat (make the circle smaller than the actual throat size so you have some grip ability to hold the LNBF in whatever skew you need), then cut the 2x4 in half so you can put it around your LNBF throat and then screw it down to the dish with 2 long screws. The screws not only secure the LNB to the dish at the focal point area, but hold the two 2x4 halves together.
Had I known about the naked LNB trick at the time, I could probably have cut out the hole in the 2x4 with a large drill bit (since the naked LNB throat is way smaller than a plastic LNB throat). I used a circle cutter and had to attack it from both sides because of my paranoia of cutting into the wood really deep with an offbalance, quality (Craftsman) wood circle cutter. I did about half from one side and turned it over and did the other half from the other side. Worked great and I felt safe while cutting it using a drill press.
I'll have to see if I can snap and post a pic here of that holder setup. Wood works great where I live - the UV is pretty damaging to plastics around here.
