Quattro LNB how to identify outputs

[localmcmoo]

I never got a chance to perfom the scans with all the cables unplugged from the multiswitch however i did manage to take a few pictures. My model does not have the dip switches. I'll have a go at doing the scans again over the weekend.
And for sure once i find out what is what the will be labelled. Not going through this again.

Nick - thank for the pointers - alas all existing cables were used. All my cables are white!

OK - great pity.
Still don,t understand how the Technomate TM-4Q ( .. and Yes, its a Quattro!! ) shows more than it should!

While you are testing the cables over the weekend ( ), first refit them to the F connectors and tape them (so you know they are good!) - I would also do that to the f connectors going to the receiver - it's amazing how these things can get loose when you are fiddling.

Ok folks - maybe i'm reading the sat link wrong.

I have detached ALL cables. I then plugged in 1 cable and did a scan on the Satlink - see pictures

The Channel 4+1 picture (the one with the cows) , i was thinking that was a Horizontal Hi (sorry i cant seem to rotate this attachment)
The BBC One NI I was thinking was Vertical Hi

Now - am i reading this thing totally wrong?
the second thing is how did i manage to see a picture on the V and the H polarity from a single cable?




Not enjoying this at all.
Any assistance much appreciated.

[twol]

If it really is a Quattro, then I can only believe that the satmeter is supplying the required current and signals to tell the lnb what to do.
So throw the satmeter away.

Connect one cable to the 1st port on the multiswitch.
Power up the receiver, go to Satfinder (under setup/service searching), type in the relevant info for one of your selected services.
Get signal - Works OK leave and connect next cable move to next selected service!
Doesn,t work move cable to next port ...... keep going until you get a signal!
Then move to next cable!!

You only have to do this for 3 cables the 4th should be fine!

Thanks Twol. Maybe i don't have thing thing figured out like i thought.

Can i ask for a favour as i'm not sure if im reading the channel information correctly.
Can you list me 4 channels all on the different polarities? Not confident i have full understanding of this. Once i have the 4 different polarity channels i can do what you suggested.

I know im not far off. My scan received 974 services. My friend tells me he has over a thousand. I'm not bothered how many channels i'm getting but what i do want to do is make sure i have everything configured correctly.

Hi mate ,sorry to bother you,but if the dish is alignment properly with Quad lnb , it easy every quad lnb they show you from output ,HH.VH.HL.VL,and the same every switch is showing the same as input ,lnb must be quad one no 4 ways ,go out side where the dish is been fix , and take all cables of from lnb and wright on the cable ,HH.then other cable VH.other one HL.and last cable VL,now all cable are marking which is one and which is other one ,with Coaxial Cable Tester ,test the HH,go downstairs and check all cables till find the HH,when you find connect it on multiswitch input HH, and test another cable ,and test all , then go where the dish is been fix the connect all cable on lnb ,cause you mark them one beginning,i think this it will help you , sorry for my English ,

regards Nick

Thanks Guys.

Nick you bring up a very valid point.

I am not confident of the installer has done a good job. I wouldn't surprise me if he has done the minimal to get the signal not knowing how a quattro works. I hired someone who i thought would posses this knowledge. If indeed the dish is not correctly aligned then i would have to call out another engineer to fix this. I would not use the same so called engineer.
After my final testing - i may open another thread to see if someone can recommend an installer who will cover the Ilford area to tweak and tidy the mess the first engineer has left behind.

[twol]

So try these 4!!
Low Band 10.70 -> 11.70:
BBC1HD 10847 V 8PSK 23000 2/3 Vertical
Capitol 11552 H QPSK 22000 5/6 Horizontal

High Band 11.70 -> 12.75:
QVC 11954 H QPSK 27500 2/3 Horizontal
VIVA UK 11895 V QPSK 27500 2/3 Vertical

Sorry for the delayed reply.

Nick from what you say i think it makes perfect sense from what i am seeing "Hi mate ,sorry to bother you,but if the dish is alignment properly with Quad lnb , it easy every quad lnb they show you from output ,HH.VH.HL.VL,and the same every switch is showing the same as input" I have a feeling the Dish/Alignment is not correct. Maybe just slightly off.

In the last few days i've emailed the switch manufacturer - please see the conversation below (it has a bit more detail in the steps i have taken with your explanation Nick and the 4 channels you gave me to test twol )



Goor morning

even that the first observation is strange, I am not surprised with the other one. It is our experience that number of tuned channels sometimes differs, it can be caused by different receivers used to test, different weather condition, ongoing changes on satellite services. Of course, also the multiswitch can reduce a bit the signal quality, making it harder for receiver to scan the transponder.
If you know which services are missing, maybe they belong to one transponder and you can try to tune that transponder manually.

Thank you for your reply

I have indeed used the method you have described to identify the 4 cables previously.
I do believe I have the 4 cables plugged into the multiswitch correctly.
I was concerned because of 2 things:

1. The behavior of the switch passing H+ signal on all of the inputs
2. When searching 28.2 for services I get approximately 994 services. My friends get over 1000. With a new dish and LNB I was expecting closer to over a 1000. I’m wondering if there is something going on with the switch

Hello

to be honest, I have no clear explanation for your strange experience. With Quattro LNB, polarities & bands are fixed to its outputs. One transponder then should not occure on more cables. There could be, however, some signal leaks (crosstalks) between the cables, if they have poorer isolation and runs closely together at bigger distance. But in that case, I think, you would observe the same results while connecting directly to the receiver.

But I guess you should not blame the multiswitch for that. Try to indentify the cables using direct connection to the receiver, because this procedure seems to be not ambiguous.
Then connect the cables back to the inputs of multiswitch. I hope it will work fine.

We can consult further if some issues would persist.

Good morning,

I have the 5 in and 12 out powered multiswitch EMP-Centauri MS58PIU purchased 8/4/2014
under the unit the sticker says MS5/12PIU-5 S/N 130314099100010

I recently had a Technomate Quattro LNB and a 95 CM Dish. Unfortunately the Installer was not great and has got the cables mixed up.
Whilst trying to decipher the cables H+ V+ H- V- I unplugged all the 4 inputs (I am not using terrestrial) from the multiswitch. I then tuned the receiver into QVC 11954 H QPSK 27500 2/3 Horizontal and plugged that into one of the Multiswitch 12 outputs. However rather than only one of the 4 cables coming from the Quattro LNB I found that all 3 gave me a picture. I tried this without the multiswitch - plugging into the receiver and I found that only 1 of the cables game me the picture (the H+ input I presume).

Is my Multiswitch faulty? Am I doing something wrong?

Attached is a picture of my switch

Regards





So with that being said and all things considered - I think my dish may be poorly aligned. I could be wrong however... but that's where its pointing to.
My next step is to get a real professional in to take a look at the setup and alignment. The fact that i'm getting all the channels that i want makes me wonder if i want to spend anymore money - however i do like things done right.
I may open another thread for a recommended professional who has the right equipment in the Ilford area.

Nick and Twol thank you greatly for your assistance. It has helped me increase my knowledge and have a better understanding of satellites and LNB's. If there is any further developments i shall let you know.

Thanks
Dee...

[twol]

I really feel for you and your issues ...... in theory this should be straight forward for an installer and everything should be clearly labelled.
With my setup it was imperative that the 28.2E dish was accurately aligned to the marginal signals (with your location you don,t have to worry about the multiple satellites supplying 28.2E) but then provided everything is labelled and connected properly it should then not be an issue...... I certainly do not expect the multiswitch to be an issue.

Hi Dee, i wish you to sort out soon you problem , i wish I am living at London ,and i could coming and fix it for you ,but i am living at Bristol mate is to far way ,
but really is very strange like you saying here ( I recently had a Technomate Quattro LNB and a 95 CM Dish. Unfortunately the Installer was not great and has got the cables mixed up.)
with 95cm dish cannot get proper signal ,that sat installer is not good enough ,
so i wish you all the best

regards Nick

I've been following this thread with interest and, @localmcmoo, I feel for the endless difficulties you seem to have had with this setup. The only conclusion I can come to is that you actually have a quad and not a quattro LNB. I know the engineer (hah!) left a box in your garden belonging to a Technomate Quattro, but have you confirmed by going up a ladder and checking? You know what they say about if it quacks like a duck etc....

He may, (I'm being generous here) have mixed up two different LNBs and thought he was installing a quattro but every test you have done on single cables attached to the LNB has resulted in obtaining signals from different polarities and from low and high bands - a behaviour you would expect from a quad but definitely not from a quattro.

In addition you said you are receiving about 994 services from Astra. That's perfectly normal on a scan. I get around the same, sometimes less. The dish is reasonably well aligned. There may need to be a slight tweaking of the skew, but it's pretty ok if you can receive signals from all services.

A quad will/should work as the switch will apportion out the H and V, high and low band in any case. The LNB may not live as long as a quattro but it should basically function.
