This is to give you some idea of what dish lnbf will work with what switches ect

LNBF
1. Legacy:
a. single: called single legacy, one output.
b. dual: called dual legacy, 2 outputs.
c. twin: big fat lnbf, 2 outputs, has 2 SW21 switch built-in.
d. quad: big fat lnbf, 4 outputs, has 4 SW 21 switch built-in.
2: DishPro
a. single: called single DishPro, one ouput.
b. dual: called dual DishPro, 2 outputs.
c. twin: big fat lnbf, 2 outputs, has 2 independent Diseqc switch built-in
d. quad: big fat lnbf, 4 outputs, has 4 independent Diseqc switch built-in

Switch
1. Diseqc: 2 versions: 1.0 and 2.0. People having problem with 2.0 version
a. 2 ways: 2 inputs, one output. Switch up to 2 lnbfs.
b. 4 ways: 4 inputs, one output. Switch up to 4 lnbfs.
2. 22khz switch: 2 inputs, one output. Switch up to 2 lnbfs.
3. 0/12v switch: 2 inputs, one output. Switch up to 2 lnbfs. (Note: 0/12v switch needs to be installed close to the receiver, therefore 2 cables has be run into your house)
4. There is no such thing as Diseqc 1.2 or 1.3 switch. The 1.2 and 1.3 (aka USALS) are for motorizing Diseqc h-h mount.
5. DP34. 3 inputs, 4 outputs. Can be used to combine a 2nd (61W or 148W)dish with DP twin or quad, so receiver will get signal from 3 sats.

Switch does not work well
1. SW21
2. Diseqc 2.0 version (either 2 ways or 4 ways).

Dish 500
1. with 2 separate legacy single or dual lnbfs.
2. with legacy twin or quads lnbf, no good.
3. with DishPro twin or quads lnbf, good. Need to use modified transponder list.

Setup:
1. Dish 500 with legacy single/dual lnbfs: use with any working switch stated above to switch between lnbfs. 2nd or 3rd dish can be added using Diseqc 4 ways.
2. Dish 500 with legacy twin/quads lnbf: replace the lnbf with single/dual lnbfs or DishPro twin/quads.
3. Dish 500 with DishPro twin/quads lnbf: good, controlled by Diseqc command using modified transponder list. 2nd dish can be added using DP34 switch

I hope this clears things up for people.

Why is the Dish 500 with legacy twin lnbf no good?

Why is the Dish 500 with legacy twin lnbf no good?

Because it has a built in SW21 that is not compatible with FTA.

I just received a Legacy quad (no DP logo) and tried it on an existing system with a twin DP. Found 0% signal received and failed the switch test completly. Tried 2 receivers 508 and 2700 both with the same result. The cable length is about 125 feet. Does anyone know what the max cable length is for the legacy quad? I know DP can go up to 200 feet. I also have a DP adapter for the 2700 made no difference to the legacy Quad. I haven't seen any adapters for legacy quad/twin. I though it should work with either receiver without any extra items. :unsure:

where can i get the modified transponder list?
