I'm going to switch out the 5LNB w/ SWM that I currently have as part of my Slimline dish with a 5LNB w/o SWM so I can use a separate powered SWM16. I noticed when looking at my current dish, that there are no screws whatsoever at the end of the feed arm going into the LNB assembly. I looked only to see what I'll have to do to disassemble this to replace with the aforementioned one. Am I nuts to think that the MDU guy who installed this dish was too stupid to use screws to hold in place the LNB assembly? Wouldn't these screws be visible? I can't see any at all. This makes me wonder how that thing actually has stayed on the dish without falling apart (or at least slightly dislocating itself). I also wonder if this would in any way cause raid fade to be more likely, because the receivers connected to this dish suffer rain fade if a bird pees on its way past the dish, but the dish off the building rarely has rain fade.
