121 question

[f2rc]

imagine you are trying to recieve signal from echostar 110, 119, and 121. For reasons of aesthetics, you can't use a superdish. you could use a dish 500 with a twin for 110/119, and another dish for the 121, and combine them with a 34.

what would you use for the 121 dish? a 500 with a dual? what would the coordinates be? Skew would be 90? what would elevation and azimith be? (assume for argument's sake you're in the detroit area, zip code 48240)

121 is a fixed service satellight... it cant use normal lnbs that you would use on 110,119 you would have to use a super dish or a primstar dish pointed at it to get it

In addition, to do a 2-dish solution, you're stuck with using all Legacy LNBFs and a SW64 because there is no stand-alone DishPro FSS LNBF available.

Exception: If you only need the odd transponders off of 121, you can turn a standard Ku-band 90 degrees and plug it into a DP34.

Why turn it? Glad you asked. The DP34 will drive the LNBF into trying to get the even transponders because DP puts out the higher voltage. However, it's expecting evens to be in the 1650-2150MHz band, and a conventional LNBF will NOT do that. So, the LNBF is locked into Vertical (even) polarity, but turning it makes it grab the odd transponders (Horizontal), and send them on the low (950-1450MHz) band - right where the switch is expecting them to be. Crazy, but it works.
