I bought some gabriel dishes probably 8-10 years ago, and they all failed, so gabriel gave us a deal on new feedhorns, and most of them have since failed too. Perhaps things are better now. We had one fail this past winter, and just took it off the tower this summer. We just tossed the dish and feedhorn in the grass and forgot about it. I'm not going to buy another feedhorn for it.
We're mostly using pacwireless for dishes as a result. We've had a few of them fail a couple years ago, but they've fixed that, and percentagewise, they've been more reliable. A radome also protects the feedhorn quite well, and we use a radome anytime where we are near the ocean or are being careful not to overload a tower, as the radome both protects the feedhorn and reduces windloading. We also only buy the dual pole ones now. We'd started to for the trangolink45's which can switch polarity with software. Now, it looks like 2x2 MIMO based products are the future for backhaul, and we'd like to not have to upgrade antennas with the radios. If you use a radome, you have to actually disassemble the thing to change feedhorns, so do it right the first time. The Gabriels are a lot lighter due to their all alloy construction.
