Mortorised Dish Control

[mforbes6186]

Hi all,

A bit of background - currently I have a 2 dish (28.2e & 13.0e) diseqc set up, 28.2e dish has a quad lnb and 13.0e dish has single feed lnb. 3 feeds are 28.2e only and 1 is combined (with the diseqc) 28.2e and 13.0e. 2 of the 28.2e feeds go to 1 room and 1 28.2e and the diseqc feed go to another room. both rooms have twin tuner boxes.

so... I was looking to get a motorised dish to pick up 19.2e and and a few others, but my question is, when I look at the Superior DarkMotor it appears that only 1 feed can control the motor, is that the case? if so, if, for instance, my box A was watching a channel on 28.2e and Box B wanted a channel on 19.2e, what would happen? And if it's the case that only 1 feed can control the movement of the dish (ie master/slave set up), do you think it would be best to leave one of my boxes on the existing, 2 dish diseqc set up and use the motorised dish specifically for the other box?

just trying to get my head round it all!!

cheers, mark

have a read of this http://www.digital-kaos.co.uk/forums...-setup-280981/ for starters

all of these diseqc motors only have one coax input from a box , so in theory only one box can control it, unless you daisy chain the boxes (not ideal)

but on the other hand you can use a 4 way diseqc switch like I do, and have the motor on lnb A , and hotbird on lnb B and sly on lnb C , leaving lnb D spare

on the other box you have lnb A as the second feed from a dual lnb on the motor , and lnb B , C and D as above

or that is how I would do it, so that one box controls the motor, but both boxes obtain a feed from the motor, a feed from 13e and another feed from 28e

so if you parked the motor on 19e, , then lnb A would in fact be 19e on both, lnb B on 13e hotbird and lnb C on astra 2 at 28e

this means both boxes have diseqc switches, both get feeds from the motor and feeds from the fixed lnb,s, but only one box controls the motor

it also means having a 28e feed to each switch , and a 13e feed to each switch , and a motor lnb feed to each switch

hope that makes sense ?

thanks, I had a read through the thread you mentioned but your post just clarifies my understanding.

basically then... if I want both boxes to have unrestricted access to 28.2e, 19e, 16e & 13e I would either need -

2 motorised dishes
4 individual dishes with 2 4-way diseqcs
or one dish with a multi lnb holder and 4 twin lnbs?

i'm now swaying towards the multi lnb holder set up, but 1 other question...

most multi lnb holders i can find have a minimum of 4degrees needed between lnbs, this would then mean I can't have 19e, 16e and 13e as there is only 3 degrees between them. is there any known way round this? ie holders with less than 3degrees between positions?

thanks

there are some bespoke slimlines that state they will get the 3 degree separation, but I have no experience of them

but you can have 13e + 19e + 28.2e on one dish as I have myself (with 5e too) , and you could have 16e on another dish and maybe have 5e or 0.8w as well

or have one motorised dish instead of a dish on 16e and one other dish containing 13e + 19e + 28e with suitable lnb,s containing twin or quad outputs as required

that way both boxes have 3 satellites to choose from plus whatever the motor is parked on, from a 2 dish setup

the problem with that gilbertini mount on the zone 2 dish is that the lnb holders touch each other on 13e and 19e leaving little or no space in between them, so even with alps slimline lnb,s you dont get a 16e in there

but yes, my triax 80cm is similar to that gilbertini on that zone 2 dish but without the 42e and sly quad lnb,s on 13e + 19e + 28e, not singles

many examples exist on various forums, but squeezing 16e in is a difficult one when trying for 13e and 19e as well

Yeah, that's the issue i've been having. My thoughts are then to go for a 3 lnb multiholder set up (13e, 19e & 28.2e) on one dish then 16e on another (static) dish. are there any issues use quad lnbs on the 3 lnb set up? I was thinking a 80-90cm dish, i'm based in glasgow

also, from reading other threads, i'm guessing i'll be aiming the dish at 13e as that is the weakest, with 19e and 28.2e offset? is that correct?

seems reasonable to me, although you may be aiming at 19e with lnb,s either side for maximum signals across the range, and dish B on 16e , with 2 cheap four way diseqc switches and I would suggest using modern sly quad lnb,s for starters as they are only about ?6 each , although inverto ultrablacks would be better
