In the United States, service providers use the intermediate frequency ranges of 950–2150 MHz to carry the signal from the LNBF at the dish down to the receiver.
@Keith, Well that appears to be the ideal arrangement and with no down side. Why is the 22 switch even around if it has all these downsides ?
2On a 4x1 diseqc switch, instead of just 4 LNBs, you can get 8 LNBs using a 22 KHZ switch on each port using Standards only.
Why would you want to do this? From what I see online an 8 port DiSEqC switch is $19.00. Where as 4 22KHz switches will cost $32.00 + $8.00 for the DiSEqC switch.
I bought my 22 KHZ switches a long time ago (been doing FTA since 2006) when I only had a 4x1 switch. At that time 8x1 switches were harder to find, and expensive, I bought my first 8x1 (EMP Centauri) in 2007 (and bought more 22 KHZ switches). It wasn't long before I put the 8x1 on port one of a 4x1, and at one time had 22 LNBs (using 22 KHZ switches, and Shaw Direct dishes which have dual LNBs that use a built-in 22 KHZ switch to switch between the two LNBs) on its 11 ports! I only recently retired the 8x1 EMP Centauri off my AZBox receiver, and am just using a 4x1 with 8 LNBs (most are the Shaw Direct dishes). On my Amiko I have a Amiko 8x1 switch on port one of a 4x1 switch, so again 11 ports and have 14 LNBs in use. I would add more LNBs if I could, but we have lost quite a few satellite positions over the years, so pickings are slim.
Are the shaw dishes the same as PrimeStar?
I would imagine a lot has to be also custom designed around what you can find. But I tell you this. Reading an advert on what my 22 switch was suppose to do as compared with actually deploying it into my system was very unexpected. But now as I have learned it appears I just need the diseqc switch and I'll be back in business.
Here is the link to the advert:

It does say: "Also can be used to send Universal 9750/10600 LNBS to 10600 L.O. Freq only"
I acquired a 1 meter PrimeStar dish and decided to set it up on a dedicated mount so I could practice finding satellites. But then I discovered it was picking up transponders my 90cm dish was unable to get so I was impressed. If I find more of them I'll grab them.
