Motorised and fixed dishes on one installation

[ezhik]

Can I have two dishes, one fixed and a motorised one working together? I think the theory seems to work, but any problems in practice? For example current loss or volts drop through the switch, or can I put the switch after the motor? Can't think why not. Any tips from anyone with this arrangement appreciated.

What I'm thinking is the fixed dish will point to Hotbird 13E, then other satellites via the motorised dish, A DiSEqC switch connecting the two LNBs to the receiver. Will this work OK?

Yes, I have a simiilar arrangement, 16E,19E and 28E on a fixed dish, and the rest on a motor.

Wire:-


Receiver->Motor->Switch->LNBs

Great, thanks for the confirmation, much appreciated.

robbo what size dish is your fixed on? and if i did same with a twin tuner pvr would i just put one dish wire in to one tuner and the other into the other?

I have it on a 1m Orbital, using their 3-9 degree offset bracket. It is a good bracket, because the central LNB is not affected by the position of the Offset LNB, which it is on the Triax.

A twin tuner receiver would be slightly problematical with a motorised dish, as the 2nd tuner would not be able to control the motor. So both tuners would only be able to tuner to one satellite.

With the Extra multi -LNB dish part of the arrangement it would be plain sailing. You would just fit 2 Diseqc switches and twin LNBs on (and a twin for the motorised). Both tuners would then have access to all fixed LNBs independently. The motorised LNBs position controlled by the 1st tuner, so as above the 2nd tuner would have to tune to the same satellite if the Diseqc switch was set to the motorised LNB position.

Does that make sense?

it does make sense sort of. its what i want to do next year when i get me pvr, waiting to see what the freesat box is like. so will prob come back to at a later date for help if thats ok. at least i know it can be done.

what size dish would get me 19 and 28e for a fixed dish? im just south of hull

I am having the same problem..But now i got answer...Thanks to you guys.

I only know what size I need down here, and an 88cm does it easily, with a nice strong signal on the offset. I would get away with an 80cm I believe.

Since you have a 70cm already, why not experiment with that? If you moved 19E off the focus a bit so that 28E could come over, you might have success.

will try it went i start the project got a while yet till i need 19e for eurosport cycling

thanks
