Is a Dish SW21 just a Diseqc switch ?

[kstuart]

Hello,

I came across a couple of old Dish Network "SW21" switches that allow use of two LNBs with one receiver.

The thought occurred to me "I wonder if it is just a Diseqc switch ?".

Anyone know more details ?

sadly it doesnt work that way. Dish uses its own type of switching in it

been there tried that

sw21 - what's inside

In the old days (on Dish) I used the SW21 and 21x.
Eventually, DishPro (diseqc and bandstacked) LNBs and switches replaced the old stuff.

Here's the site I found with quite a bit of info on that venerable old switch.

A little off-topic for this department, but still good technical info:
I keep a few SW22's around for special uses.
Turns out, they pass power to both LNBs regardless of their position.
I use one with two $10 meters when aligning two LNBs at once (yes, even dishPro)
As you swing the dish across the sky, if both meters don't peak at the same azimuth, then your skew is wrong.
I've used that trick with an off-plumb pole (15º) to find and align on two birds.

the sw21 is DN's proprietary command switch protocol, see here for more info, including info on making a protocol logger.
