I have a dish that like the one in these two pictures (the one on the right in the first picture). Any idea of it's make/model? Anyone know if it's any good for Ku?
I'll second Prodelin, the back structure looks like a Prodelin but the mount doesn't. A lot of fiberglass dishes were copies of good quality brands. A fiberglass dish won't work as a satellite reflector without a metal layer embedded into the fiberglass. Early fiberglass dishes had reflecting surfaces with holes too large for Ku band but worked for Cband.As an owner of several Channel Master antennae ( 3.0m & 1.2m versions) (plus looked @ several hundred pictures of them) I disagree that it is a Channel Master. It certainly doesn't look like any Channel Master I've ever seen. It looks more like a Prodelin or M/A Com dish.
It is a Prodelin, I have the same one but with a different polar mount. Good dish dish very HEAVY and it is hard to keep stable.
