Of course, you can always find an inexpensive Dave TV dish on craigslist with a single LNB for cheap ($15-$20) and mount it so it is aimed at 91w so if and when both service providers are back up and running, you can use both dishes for both providers.
An inexpensive 4x1 switch or a 22KHz switch to separate the providers will be needed, but you'll be able to switch between 91w/110w/119w almost instantly.
I would opt for a 22KHz switch - keeps things really simple, especially if you are already using a DN dish with a built in Diseqc switch for 110w/119w
Just connect the output of each dish to the 22KHz switch and set your antenna settings accordingly to match your hardware setup.
The Ecoda 22KHz switch is inexpensive, fast and dependable as the sunrise.
The pic below shows what a 2 dish setup would look like.
The single LNB dish (top of the pic) is pointed at 91w while the double LNB (bottom of the pic) dish is pointed at 110w/119w:
The type of LNB you are currently using for your DN dish will determine what kind of switch you may need to make both dishes work together.
If the DN LNB's are "Legacy" then you can just connect the Dave LNB to the existing Diseqc switch, probably to port #3 if it's not in use or port #4 if its open.
Otherwise, you'll probably have to opt for the 22KHz switch.
Then there is always the fun of a 36" or bigger Dish on a Motor and an Invacom Quad LNB that lets you get all kinds of stuff from all kinds of satellites and is a lot of fun to play around with.
You keep your smaller dish with the two LNBs for the sats you watch the most, like 110/119 and then you use the Big Dish to hit all the other sats that you can get like: 61.5w/82w/91w/97w/118.8w/123w/129w/148w
depending on where you live and what you can get.
It's a lot of fun.
For about $200.00, you can get yourself a 36" dish if bought locally for about $60.00 (shipping can easily double that cost) and Invacom Quad LNB that allows you to get both Linear and Circular sats with one LNB (About $55.00 delivered) and a good quality motor like a DG-280 (About $80.00 delivered)
Factor in a few more bucks for RG6 cable and a Chieta HD 4x1 switch and/or an Ecoda 22KHz switch and for a little over $200.00, you can hit about a dozen or so birds, many of them "True FTA" sats and many not, but either way your viewing horizons will be greatly expanded.
Once the channels are opened up again, I would highly recommend this setup to those who are serious and want to get the most "bang for their buck" when it comes to this "hobby"
