The dishes feed and arms look like a channel master?

If it is get it home quick! Does it have the polar mount?

 

[handsomejackuk]

thanks all for your info will try settings on receiver l8r i assume the polarising lnb has some sort of stepper motor on it to enable it to turn through 180 degrees as i think a polar mount is not the same as stab motor mount i.e. the dish turns and no skew adjustment with modern setup. modern lnbs only v and h polarity. is there any way of putting a voltage up the polariser connection to turn the lnb. i have six additional wires coming in from the dish would these be 4 for the positioner 2 for the lnb (plus the coax which i can identify.) is there anyway of identifying these cables with a meter without going up to the dish ?

The polarotor servo motor needs to be pulse driven (+/-5V pulses). Only receivers with this facility can be used. By 'two for the LNB' I assume you mean twin and screen (+5V, pulse and ground).

total flexes are 4 one being the coax inner and outer braid, two flexes which i think are the motor / positioner (four cables total) ,and one flex going to the lnb polariser with two calbes inside.

thanks Alun

So the latter cable is the one that needs to be connected to a receiver's polariser output. Conventionally, the wiring is normally Red = 5V, White to pulse, Screen to Ground.

Its deffo a channel master 1.2m /1.8m with ku-band feedhorn and i think the lnb is made by norsat best would to be to change it for a c120 inverto or invacom.

The thing i can not understand is why have they got a D2-MAC decoder in a school maybe the teacher use to stay late to watch the late night movie on filmnet/tv1000

Sounds like a Decoder box of somesort to me, old analogue boxes usually have 2 or three Scarts on the back, my Pace MSS300 has 3, TV, VCR and Decoder, but it it is a decoder, then you have a very nice doorstop as it'llbe completely out of date now...

It could possibly be a pal-secam transcoder for the French channels.

Wouldnt be Brynmawr Comp up by Control Data by any chance they had a similar decoder in the back of of Mrs Sheens class.

I used to always look enviously at the old Dish up there and never got used.

I was told she was fired up to view CNN international on the day after 9/11 but that could be rumor.

Remlap...

come down the road about 1/2 mile and your on target nantyglo comp...

 

[remlap]

Ah im guessing they both had Mac Decoders due to similar kit being installed at both?

Only been in Nantyglo Comp once or twice I think.. for taster days after leaving primary years ago.

 

[handsomejackuk]

probably same setup as brynmawr as they got similar dish. Wonder if they still use their kit ?

When I left nope it was not beeing used, the decoder was stacked up the back of the head German teachers class.

 

[handsomejackuk]

wonder if i can borrow it (Long term) who was the german teacher when you were there how long ago did you go there...

Alun....

 

[remlap]

Mrs Sheen I think it was.

I left about 5 years ago nearly now.
