Need Help wiring Multi switch

[leifkenn]

Hello I am looking for some assistance in wiring up 2 KU-band dishes.
The idea I had was this.

2 dishes connected to one port each of a diseq at the dish.
1 cable running to the house and into a 2x4 Multiswitch with TV in.
OTA antenna connected to the Multi Switch.

1 cable running from the MS to the receiver then a diplexer to split OTA and FTA

The problem is that when I try this I am only getting one satellite and that is 98W.

If I take the switch out of the mix I am able to use both satellite's.

Is there anything that I can do to make this work.
Thanks

Take a look at the Switches Simplified FAQ, in the . . . FAQ department.
See if there is something that better matches your setup.
Do you have dual output LNBFs?

I have looked in there and all of them look to have the multi switch first the the diseq.
I have single LNB Directway dish's

Here is a drawing of what I have.

Well, as you've already discovered . . .
... that won't work.

edit:
OH! I thought you had two FTA receivers!
Since you don't, put a diplexer in place of the multiswitch!
Think that should do it. - :up

Save the multiswitch for another project.

I will try that but in the very near future I plan on adding a few more receivers once I get them bought.

I just re-read the first 10 posts of the Switches Simplified FAQ.
After three years, it holds up pretty well.
Just found a few typos I'd change today.

It documents how to run multiple receivers.
All LNBFs need to put out both Vertical and Horizontal at the same time, to allow any receiver to select either.
That requires two-output LNBFs. And multiswitches.
Good examples are given in the FAQ.

One problem is getting LNBFs to match the elliptical DirectWay dish.
Common LNBFs have round feedhorns, and won't see the entire dish surface.
(or they may see beyond the edges of the dish, picking up background noise)
So for elliptical dishes, you really need to recycle the existing feedhorn.

There are some (expensive) Invacom LNBs that'll mount to Primestar/Andrew/ChannelMaster Ku feeds.
To mount on the DirectWay feed, may require some drilling on the feedhorn.
(I have 'em, but never really got as far as mating 'em up)

Another popular solution for flange-mount LNBs, are the FSS lnbs from DishNetwork 105° or 121° SuperDishes.
The LNBs are bandstacked, so they supply both V & H polarity simultaneously on a single wire.
This is one of very few instances when high frequency satellite-grade splitters might work.
A better solution, if you follow this path, is to figure out a way to use surplus DishNet DP-34 or DP-44 switches.
The 34's are dirt cheap. The 44's are probably still outrageously priced.
(a single DP-34 would allow for 3 LNBs and up to 4 receivers)

I came up with a plan a few years back to use two DP-34's and some eCoda 22khz switches to make up a 6-lnb by 6 or 8 output switch matrix. (6x6)

Sadoun also sells a complete Ku LNBF and a C-band LNBF which are bandstacked.
I'm not pushing the bandstacked idea.
But it's the only option to dual-output LNBs I can think of.

Thanks I will have to look into that.
My grand plan is to have 3 Kuband feeds and one C-band on my 12ft mesh dish feeding 4 receivers.

Please refer to this picture I posted in another thread.
The rectangular object 2nd from the right, is my DirectWay feedhorn.
The flange is facing the camera, with eight holes in it.
They are all threaded.
The far end is very distinctly rectangular.

(To the far right is a DishNet FSS LNB, and above it is the 105° feedhorn.)

Other DirectWay dishes have a tall oval feed horn, much like the front row, 2nd from the left.
It's the one with the long neck, and is bolted to a DishNet FSS LNB, same as lower right.

Is your DirectWay feedhorn the rectangular style or the tall oval style?
