I can't work on my 10' unless I drive it down to 123 or 125 , without fear of either falling into the dish or falling off the ladder. When I had that old 12' thing up, had to take it over to 135 or so or never reach the lnb at all.
But how would you adjust the LNB for channels in the middle?
I know that the THEORY is that you adjust it on any one satellite and it will work right on all of them but I have NEVER found that to be true, at least in my limited experience. I usually end up aiming at the one satellite I want the most and try to adjust it to that one, and more specifically, adjust it to the channel I want.
Case in point: You can have the LNB taped to the neighbor's tree with scotch tape and aimed at his dog house and you will still get NASA on 87. But it's always been very hard for me to tune in the good stuff like Me, This, RTV, etc..
Same thing on 123. I could hold the LNB in my hand away from the mounts and get several of the religious channels on there but getting FSTV was a true nightmare.
I was thinking back to a long time ago, back when I was married and we had an old C-band dish. At that time I had absolutely no knowledge of it's mysterious workings. We had a subscription and we got a big FAT TV guide in the mail every month. They pictures were always fuzzy and static filled, I think we called them sparklies or twinklies or something like that. There was a knob on one of the tuner boxes you could turn to help clear it up, sometimes.
In retrospect, I'm thinking that it might have been a skew controller. I sure with there was something like that for these new dishes. It sure would make life a lot easier if you could just turn a knob in the house a little rather than go bumbling around on a ladder and break your neck..
