what lnb are you using ?

on that size dish, you will be best to use the channel master feedhorn and an invacom c120 lnb

also what receiver are you using as you will need one with a good tuner in it

riproaring · 28-09-2008

the lnb is andrews feedhorn with inverto0.3db c120 lnb and the receiver is a technomate 5400+ any advice. the thing is it picks up loads of nilesat channels but nothing on transponder 15 the engineer fitting it cant a reading on his meter for it

One would have thought a dish of that size should readily pull in Nilesat H TPs! Anyway, if the verticals are constant during the day, could you wait till about 10 PM and then check some of the H TPs especially 11996 and 11919. Generally, you are more likely to get best reception from about 9 PM through the night; thus, testing for signal (and any change in signal quality) may just be easier around then.

For H transponders i would try 12303 H 27500 3/4 (TP 31) and tweak to maximize the signal, skew the lnb and then try the showtime transponders.

riproaring · 28-09-2008

the engineer has got a signal on his meter with a picture on the testing kit and a pass signal, when he connects it to the receiver we get no signal, tried 3 diffrent boxes and nowt anybody any ideas

BoSSpak · 28-09-2008

need more information

the engineer has got a signal on his meter with a picture on the testing kit

I take it he's connecting his meter at the dish end ie connects equipment directly to lnb.?

but where are you connecting the recievers, inside the house or outside near the dish?

when he connects to the meter inside the house he gets it on a small screen but nothing from the reciever (s)

Best to take reciever + telly outside.

Connect a short cable from lnb to reciever and see if you get a signal.

riproaring · 28-09-2008

the engineer thinks it is lnb is faulty cant pick up any horizontals any advice

pedro2000uk · 28-09-2008

can't you test the h's on 8w?... or turn the lnb 90 degrees....and swap the tp 15 to v in the stb to test that

NeroAer · 28-09-2008

I'm the engineer concerned on RR's dish, I use a Rover analyser and can get all the Vertical channels no trouble whatsoever, When I change frequencies on the meter it still comes up with the same listings as on the transponder settings, but in order to get a signal at all on that setting, I have to turn the lnb 45 degrees (move it from 6 to 9, Having never installed a 2.4m dish, but doing IRS systems the only conclusion I can now come to is that the LNB is faulty and not receiving the Horizontal channels whatsoever, we are definately on the right bird as we get all the listings for ShowCinema.

pedro2000uk · 28-09-2008

It could be a faulty lnb .. but you know by now that the H's are far harder than the verticals which you could get on half the size there

btw.. 45 degrees doesn't compute ...

try swapping the polarity in the stb of 11919h to 11919v (a stronger H tp) and turn the lnb 90 degrees that will tell you if it is the lnb not switching to H..

BTW ... what numbers on the tm do you get City 7s tp? (11862v)

NeroAer · 28-09-2008

Pedro, RR will have to tell you that As I'm not there now. We have spent all day there re-aligning, re-skewing etc etc, but with no luck whatsoever on the Horizontals. As you can see from the picture section on my site the cable run isn't very far either as the room it goes to is just to the right of the dish as you look at it. Website address Removed

NeroAer · 28-09-2008

Website removed Again and it's not too far from the room either (maybe 10 m in total) I'm not there now Pedro, but RR may be able to tell you

NeroAer · 28-09-2008

Pedro, when I say 45 degrees, I lined the dish up with the lnb pointing to 6pm, when I found that none of the Horizontal channels were working, I put my meter onto transponder 15 (11.996.00) and skewed the LNB until it was then in the 9pm position, As most of us know, we should have picked something up on there well before that before the Vertical channels started showing again, I use a Rover ST4. So assume everything is cushty, I lined up originally on T14 and got it no trouble whatsoever.

**michael01707** · 28-09-2008

If you've got your dish set to get the strongest signal on the 7w verticals then you can check the high powered 8w European beam frequencies without moving the dish. If you can get the verticals and not horizontals then it would be the LNB.

pedro2000uk · 28-09-2008

to be setting up on 7w and just happen to have an lnb that is nackered on the H polarity is.. really unlucky.

6pm to 9pm = 45 degrees?

btw .. you need to upload pictures on here.. quick process.

you in N Staffs?

hey up mister still pulling my hair out

NeroAer · 28-09-2008

Evening RR,

Attached is a photo of the dish we've put up.

Pedro, RR is going to contact the dealer tomorrow to try and get a new LNB sent out, I'll also try the other options when I next go back.

We are in Stoke mate

NeroAer · 28-09-2008

BTW ... what numbers on the tm do you get City 7s tp? (11862v)

RR, has just checked City 7 TP and it comes up with 86% strength and green on the quality with 58 - 62 %

**michael01707** · 28-09-2008

Is that fixed to the wall?!!!

NeroAer · 28-09-2008

Yes it is Michael, the back plate is massive, I have to say it was not me that fixed it there. But it is above a flat roof so RR has to be careful that he didn't damage the roof.

I guessed 84% Q 75% S... but you can't really compare .. but that does indicate lower quality / snr .. than you'd expect?

I was 10 minutes away this afternoon .. could have let you check it with another c120 (or box of lnbfs) ...

we do steel work if you get any problems with that wall mount...

**michael01707** · 28-09-2008

Wow, I can see how big the plate is! My 1.8m is really heavy so I can imagine the weight of a 2.4m. I personally opted to put mine on a non penetrating roof mount. I've added a picture. I need to add some patio slabs to mine soon before the strong winter gales come.

That is a bit of bad luck too. Can be quite confusing on site but turning the LNb as said 90º and changing the polor on meter will show you the H results
