Interesting question about the radomes. I don't know how they are currently oriented. I always thought the radomes should point down, so a leak around the radome wouldn't let water into the RF feed assembly.

Your information about the RF feed is the kind of info I was hoping for. The model number on the RF feed does indicate it's for the 8' dish, and now I know what the extra mounting flange is for.

Still hardly any comments about RF feed lengths or dish focal point.
