I have

pf sat dish with single LNB and TD88 dish with four twin Inverto Ultra Black LNBs

I would like to know what Spaun diseqc switches I have to buy to get signals from
- pf dish and all port 1 of TD88 LNBs to DM7020HD 2 x DVB S2 and
- all port 2 of TD88 LNBs to my old 1 tuner dreambox DM5620

I am not sure what to chose 2 x SUR or 2 x SAR - each diseqc to connect to one receiver
 
To go above 4:1 your cheapest option is an 8:1 or 16:1 from EMP Profiline.

If you want to use Spaun to get 5 LNBs into 1 down cable you can either use 2x SUR (set up as mode 1 and 3), or 1x SUR and 1x SAR (or a cheap 1.0 alternative).
 
thank you for reply

I would like to have 4:1 In 2 rooms from 4 twin lnbs
the pf lnb would be only connected to one dvb s2 tuner of DM7020HD the other tuner of which goes to diseqc switch

I have not worked with switches that Is why I do not know which switch 4:1 to use SAR or SUR
I guess that I need SAR 4:1 connecting all LNB port 1 to one receiver and SAR 4:1 connecting all LNB port2 to other box
 
Well if you just need 4:1 you could use either the SUR or the SAR, but the cheap option is any DiSEqC 1.0 switch (Spaun ones aren't so cheap).

so I need two 4:1 simple switches which will work Independent with 4 twin Inverto Black Ultra LNBs
I would like to use SAR411 because of quality - I need switch with min signal losses
are there any good alternative for 4:1 switches to Spaun In terms of signal losses
 
Generally the signal loss through diseqc switches is unimportant, unless the cable run is very long, or particularly lossy. What cable runs do you have? A 10m length of decent RG6 type will lose 3dB or so on its own.
 
I use _http://uk.farnell.com/image/610073-100m-black/cable-coax-cx125-black-100m/dp/4317579

I am only worried If this cable Is proper for outside installations as It Is pvc
also twin LNBs are two Independent single LNB right ?

MODERATION NOTE

Please remember - no live links to outside sites
 
How long is the run? and yes a twin Lnb needs two runs.

Yes. In your case 4x Black Ultra twin, and 2x DiSEqC 1.0 switch.

20 m max dish to receiver
I think to mount diseqc switches on the mount at the back of the dish

thank you Huevos and Robbo for support
