Thread: convert superdish to true fta use

i have not seen this posted before so i will describe a simple way to convert a superdish for true fta use. 1. take apart the original lnb by removing the screws holding it together..discard the lnb. 2.drill holes to match the new linear lnbs mounting holes..you must use the "square" type of lnb as the other style will not fit in the arm. i used a roc model 785a linear lnb from e-bay but other linear models you may have should work too. 3. set the tilt and elevation adjustments for your area. 4.aim and peak signal. thats it. there are other ways to use a superdish for true fta but this one works for me. just be SURE to use a linear lnb like the one in picture #3 to assure proper fit and performance. i get g-10r at 60-70% quality in sw.va. with this set-up. the square style lnb makes it easy to add another linear lnb on the side for ia7- white springs tv- if you wish. see attached files for pictures.

Or I will if I wind up with too many.

Trying to corner the market? -

send them my way

Nah, not trying to corner the market, just was cringing at the word "discard" The trash is no place for such a useful item...

I think we'll be seeing plenty of the Dish FSS stacked LNBs, and the great thing about them is that they are very useful on any feedhorn with a C-120 flange. This means CMs, Primestars, DirecWay dishes, etc. There's also the T-90 application, as JerryT has done.

Here's how I mounted my lnb to the end. I didn't put it in the end, I tried to line it up like the original lnb pointed at the dish. It was just my best guess looking at it.

I have converter several SD's to True FTA by removing the lnb's fron the bracket and cutting and drilling a 1/4 thick piece of plastic that mounts to the SD bracket and holds a 40mm LNB bracket. I discovered today that the FSS lnb also bolts right up to Primestar feed horn, can't wait to try it out.

the superdish 121 or 105 lnb works fine for true fta with out any modification, notice all the guys asking for the "discarded" lnb hehe
