Here are the few dishes I have managed to scrape up and hobble together to date. Top Right (background) is a WSI 99cm x 90cm and the only one I have purchased so far. It works well. At top left ( again in the background ) we have a Slimline which I pulled from my neighbor's trash, paired with a GeosatPro SL1PLL LNBF. It will now be retired. It has taught me all it can. It doesn't pull in everything but it pulls in at least one or two TPs on each sat which is enough to teach a newbie where the sats are IMHO. It was the dish I caught first signal with and it taught me how to point a Ku dish. It taught me a lot in a short time ( I'm an exceptionally fast learner). Next on the bottom left ( foreground ) we have a strange little oval dish with no manufacturer's markings of any kind. Does anyone recognize it? It is quite rugged and is well built. It was a freebie. I'll put an LNB bracket on it to see how well it does before I paint it. The dish on the right in the foreground is a Samsonic made by Wahoo Tech INC. It was also a freebie. It came with an Invacom quad polar LNBF which I have not tested. I was told it is about 8 years old. I have no experience with the Invacom. Can someone advise me on it's quality? Is the Invacom worth bothering with?
