I have another question about the qph-031. Does it make any difference which port I connect to the motor? The linear or orbital, or no difference? Any input appreciated.

either one works fine. Just make sure you are hooked to the L port :)


The L port meaning Linear??? I just ask if it makes a difference between L or O. I'm a little confused.
 
The QPH-031 Invacom has four outputs, two Linear and two Circular. I would hook up to one of the Linear outputs!
 
With the QPH 031 if two receivers are each connected to the two L outputs can each receiver use a different polarity? What about LNB power? Should both receivers have the LNB power on?
 
yes and yes

Both LNB's can output either H or V so that is no biggie. I do it all the time.

Technically if you had the dish at AMC4 (101W) you could technically have 4 recievers off one LNB (2 DirecTv and 2 FTA)
 
Whats really nice about this LNBF (the Invacom QPH-31) is that, since the linear side is standard (not universal), you can use a 4 x 4 22k multiswitch on it to give up to four receivers access to both polarities on both circular and linear satellites :)

Funny you should say that! DMSi just added the below diagram to their web site!.........

cool :) Some of us have been doing that for a while now

I used a 4x4 multiswitch (that DirecTv uses) so you only need one switch (instead of 6) :)

65 MPH wind gusts and 90 cm dish.

how many degrees of the arc does a 1.2 meter "see"
