View Full Version : Have I purchased the wrong type of lnb?

Recently, I purchased a black ultra quad lnb.

I have been trying to set up a new motor and although I am finding strong signals with my meter, I am not actually finding anything on my vuduo.

I have just noticed that the four outputs have this written underneath them......

V Low / V High / H Low / H High


have I as I suspect, purchased the wrong type of lnb?

I am thinking that this one is not for general use.

This is what I purchased.

Inverto IDLB-QUTL40-ULTRA-OPP Quattro LNB 40mm 0,2dB Black Ultra

Sounds more like a quatro LNB than a quad.
Just noticed your second post and you have got the wrong type LNB.
A quatro is more for distribution, through an apartment block, as it has separate connections for high/low band, and vertical/horizontal, I suspect you want a quad LNB, 4 individual outputs that act like a normal LNB.

AAaaaaaaaaaaaaargggggggghhhhhhhhh h.

Damn!

That is what I was thinking.


I shall have to get the correct one.

No wonder I spent all yesterday trying to get anything from 0.8 west.
Lots of signals on my meter but never anything found.

I shall replace my old lnb until I get the correct one.

You could still use it in a good quality loft distribution board that caters for Sat/Freeview/Dab/FM.

I thought it was a quad when I ordered it.

Ah - so maybe thats why I didnt get the hoped-for improvement with JSC Sports on 7W with the Black Ultra Quattro High-Gain Low Noise 40mm LNB HDTVDVB-S2 Compliant 0.2dB I bought a couple of weeks ago, as against my trusty Sharp LNB?
I now assume I've bought the wrong one too?:confused:

a quad lnb allows each output to send any one of the 4 states it is required to use

a quattro has the following (as in post #1)

HI-V
LO-V
HI-H
LO-H

and is designed to go into specialised equipment for multiple distribution like in hotels etc

so each output only gives a quarter of the total that a quad gives

Hi mate, I think I may have done the same as you - so what is the EXACT spec of what we SHOULD be buying please mate?:respect-055:

Yeah if you is using just one sat box then Inverto Black Ultra Single LNB is just fine .
Ive never used anything other than a Single LNB myself
i got 4 motorised dishes and 1 fixed so that covers just about everything i thinks :sifone::respect-048:

Quite excited now guys - even a small improvement just MAY pull in 7W JSC Sports HD channels at times on my TM6900HD Super in North Lincs with 1.1M dish!:respect-055:

I don't wish to disappoint any of the above posters but, last week I replaced my dual titanium with a single Inverto Black Ultra only to find the sig. strength dropped instead of the increase which I had been hoping for, with jsc. 7w in mind. I had to replace the Titanium. Looks like a bigger dish is necessary for me to receive these chnls. Many thanks to DOGMAN for this thread as he has probably saved others from making the same mistake.

Well, to stop any confusion, just get a Technomate Gold LNB .1db, much better performance than any Inverto Black Ultra.

I know people here swear by them, but I have tried both over the years, & in EVERY installation I have done or tested, the TM Gold gave better signal levels & sustained lower signal levels much better than the Ultra ones.

I'm with you on that one, I always use the TM Gold .1db lnb, always gives better performance than the Ultra for me anyway.

And as stated before I've always sworn by the now unobtainable white Sharp low noise LNB - which in all OTHER ways is brilliant, so really hoping this black inverto really DOES 'do the business' on 7W, unlike the white Sharp!! lol!!:respect-050:

Theres no substitute for a correctly alligned dish and of course a suitable sized one.

Yes mate, I think maybe on this occasion it really IS a case of size DOES always matter! lol!!:respect-applause-00

Looks as though my dish is JUST too small - tried black inverto which arrived today (brill dely! - tried moving it in four diff positions near to & away from dish too) - but still no HD 1-6 on any 7W's at all - so prob find it again later, but obviously not at 3pm when I need it for Saturdays! lol!!
See four test channels 11013H on 13E still not showing any sign of becoming JSC Sports 1-4 HD either - SHAME!!!:cuss:

I'm with you on that one, I always use the TM Gold .1db lnb, always gives better performance than the Ultra for me anyway.

i have the TM-1 Gold LNB but i replaced it with the Inverto Black Ultra,
and i have to say ive been very impressed with it especially on the weaker satellites,
IMO the TM-1Gold LNB works fine on most satellites but its on the weaker ones i noticed the difference,
to be fair though i have been reading that with the Inverto Black Ultra,
some peeps have been getting different results with the single, twin and quad,
with the twin being slightly better on certain frequencies...

Based purely on reports over the years on multiple forums, the Inverto Black Ultra seems to be accepted by the majority of people posting as the best available on the market.
They can't be all wrong.
This is the first time I've seen the TM-1 Gold recommended.
I don't use either of them, so I've no direct experience of them.. just commenting on years of reading.

Was getting a 52-53% qual signal at 1800hrs BST on HD channels on 7W tonight so PISH about 1500hrs Sat afternoons with black inverto, eh - so JUST opening them 1.1M dish etc etc!!!!:respect-050:

to make you all feel a lot better I in fact have one of these as well,,,,,made the same mistake,,,,,,,,,,,,,was very cheap at the time ,,,,in future I will read the description.

Yes mate but MAYBE its very marginally better with the black inverto than the white Sharp - but it really depends on the time of day - and as I say unfortunately the very WORST time of day does appear to be 3pm in the afternoon, worst luck!
I will try the black inverto for a few days to give it a fair crack, but there really is SO very little in it - and that IS now with he correct black inverto after all the earlier confusion with the black Quattro!! lol!!:nopity:

PS: Yes manic01 I DID try moving it along the clamp - its now at its FURTHEST point away from the actual 1.1M dish!

JSC Sports HD 1-6 all opening on TM6900HD Super with black inverto LNB 1.1M dish at 58% signal quality at 0130hrs in morning in North Lincs - so not great for 3PM EPL matches on Saturday afternoons!:respect-050:

so its either double your dish size, OR sell up and move down to kent ;)

Yes mate - I do keep stating that I'm now assuming that my dish (1.1M) in MY area (North Lincs) MUST be too small on this mega marginal reception footprint!
I had simply been hoping that MAYBE the black inverto might have helped gain a couple of percent!:respect-057:

Deffo thinking of seeing my satellite man to investigate what sort of deal he can do to exchange my 1.1M dish for someting a little bigger - say 1.2 or 1.4M!!:respect-069:

just remember that with a bigger dish you will need a polar mount and actuator, and a vbox to control it from your diseqc/usals boxes

you will probably need a different type of lnb as well for the bigger dish as it may well be prime focus

and it requires planning permission for a dish larger than 100cm in england and wales unless its ground mounted on a so called "temporary" stand

cosworth and barney and satwyn etc will know more about that, so start a new thread in the dish forum about it for further clarity

You will need more than 1.2m

I am south and east of you ( village between Felixstowe and Ipswich)
My 1.2 channel master only picks up 7w H about 75% of the time in summer, then as we tilt away about 40% of the time in winter.

My 1.8m Channel master picks it all the time with no problems

afraid dish size is king the LNB make very little changes is the truth I have found with the same dishes now for 20 years+ and may different LNB's polorisers, and now just use a cheap 0.1 darkman lnb. Have a draw full of old stuff tried and did not help to get the 1.2 to work full time.

Thanks guys, very helpful - I think maybe I'll hold fire for time being to see what transpires with the whole JSC Sports picture - after all much of EPL etc (plus Championship) can be found elsewhere anyway - its just that JSC Sports is all in one place for convenience sake - plus mostly with English commentary!
Its also fine in SD on both 3.1E and 13E too!
Thanks again!:respect-055:
