I currently have a 33 inch dish aimed at 91w. Would it be possible to add more lnbs to receive other satellites? If so, what other satellites could I hit with a dish aimed at 91w, and how would I go about adding these LNBs?
Looks familiar. I may have visited there a few years ago but did not order because of not wanting to ship from overseas. I have since ordered stuff from China so no reason not to order if they appear reputable and shipping is fair. They certainly have a lot of stuff.While searching for something similar myself recently I came across this site from the UK. Anyone have any experience with their brackets and/or those "narrow" LNBs?

What sizes are your dishes and how did you come up with the focal point, accurately, with the multiple LNB's?
My experiment seems to work. The one on the left is a 1.2 m with lnbf’s pointed at 91, 97 and 103. I think the one on the right is .84m with lnbf’s on 95 and 99.
Is there any additional advice you would have for both a 10 ft dish as well as a 12 ft dish. We have 3 LNB's per dish. I'm not an engineer but am great at math. The only formula's, for focal point, I can find are for single LNB's. We're struggling here and need to get the boom lift back ASAP without havign to spend another $1200. I'd appreciate any advice you can give! Thank you!!!Yes, you can add LNBs to that dish with some success (see my signature for some of the ones I get on 80cm and smaller dishes). You should be able to get 97W without much problem. It is possible that you might not get all the transponders (depending on your location in its footprint) but, for example, I do get all the transponders on 97W on my 75e elliptical with an LNB 6 degrees off centre. Of course, your mileage may vary.
You need to make/acquire a bracket to attach the LNB to (search on multiple LNBs on the forum will bring up some examples of brackets, as well as pointing instructions).
To aim it correctly, looking at the dish from the front, an LNB for 97W will be to the right hand side. As well, if 97W is higher in the sky at your location than 91W, then it goes lower than the LNB at 91W, lower in the sky, then higher (it's all backwards). There will be a gap between the outer edges of the two LNBs of around an inch or so, but you will be able to tell by moving it in small increments.
Due to the size of the dish, 6 degrees off centre will fit comfortably. You could try for 95W (and on the other side for 87W) but the LNBs would have to be crammed against each other, which probably would reduce signal, and may be to unusable levels.
It is all experimentation, and your results may vary from mine, but even if, for example, you only get most of the transponders on 97W, at least you have something extra to watch. Good luck!
