So after several weeks of experimenting, I've discovered that I watch 91 for C-band the most. I also spend a lot of time searching wild feeds on the 91 Ku side. Titanium said a dual band C/Ku LNB is not recommended on a 1.2m dish, so I'm curious if anyone else has ever come up with creative ways to do this? On the Geosat Pro 1.2m dish, one must lower the support arms by about 3 inches for the C-band LNB, so I'm wondering if I should try attaching the Ku LNB to the top of the C-band LNB?

You'd be better off figuring out how to mate a standard KU lnbf to that dish, in conjunction with your c-band lnbf with scalar.

I always wondered what would happen IF you drilled a large hole (like a keyhole saw hole) in the appropriate place in your conical scalar, and stuff a ku lnbf in there alongside the c-band one that's in the end of it... You'd need one along these lines, but ATM they are asking way too much for it, compared to what it used to cost. Maybe somebody has one to donate to you, or you can find another model with a real small builtin scalar: Satellite AV, LLC - Satellite Broadcaster Support and Equipment Distribution

Haha I actually used to have 2 of those bullet LNB's and I sold them! Never thought I'd have another use for them :facepalm

I saw that done years ago by someone on this forum I believe and I think it kind of worked

Remember those old larger Dish Network "Superdish" dishes from years ago? The ones pointed at 105w, and also picked up 110 and 119? They also have a very small ku lnbf in there, with a skinny waveguide tube. MAYBE you can get one of those, and see if you can MacGyver a solution...

Back in the day, 2004-2007 or so, a guy from the midwest (possibly Kansas) did a lot of mini-bud testing on his 1.2 metre dish. He had posts all over the internet, including the UK. His user name was Walrus 1952?? or 1962??. I searched for some of his posts last week, but didn't find any. They maybe in the archives. Last I heard, his nick changed to Mike on this site.

Back then he was making his own conical scalers out of aluminum flashing, trying out different formulas. I won't elaborate much more, but at the end he was using his flat scaler on his dish. He even glued a socket on the outside of his scaler which he claimed increased his quality.

I'm saying this only because your in a similar footprint. I f you truly want to experiment, I would use your flat scaler and put a v-notch or hole in it and give it a try. This way you wouldn't ruin your conical scaler. You may be surprised with Cband results on the flat scaler.

I believe that Walrus is MikeI

Where do I cut the notch in the flat scaler? I will definitely try that.

I'm highly skeptical it will work, but I would notch it at 12 o'clock. You could spin it around to any position. Tilting the lnb up or down, sideways, whatever? That is the fun part.

First, of course I would try the flat scaler on your c-band signals to see if you can still get the channels. Everthing was Dvb-s when I was experimenting. Much harder now. Up here, a flat scaler was useless on my one metre.

Tried the flat scaler on the 1.2m dish. Had a few femarkable results, including boosting the signal quality of the CW mux on 91 to 80%, Shepherd's Chapel on 99 to 100%. But caused Lesea mux to drop to next to nothing. So I think its case-by-case.

I put the conical scaler back on and blind scanned 91. I really think I'm in the prime focal point, because I scan in 73+ channels.

Sure would be nice to have a legal FTA pay TV Cband service, because a lot of the channels I want are on 91 and they come in strong but scrambled :(

It's almost 60 degrees today so I changed up some things outside. I remembered that 97 is a strong satellite, so I put it as an offset on my 90cm dish. That solves the problem of 91 Ku; it has its own 76cm dish now.

So now I can see 87 91 97 and 103 Ku and have a dedicated 1.2m for Cband 91 :)
