Channel Master 1.8m with new Feedhorn WORSE!

[radicaldoc]

Well not what I expected....................By any stretch of the imagination..
The only one I am getting any decent lock on CH4 HD and 4Seven is the Feed Horn with the Invacom Twin.
So I agree with you Sleepy Hollow the feed horn is definitely the way to go...

Channel Master Feed Horn with. Invacom twin. C120...........................H S/88 Q/100
V S/82 Q/8

Channel Master Feed Horn with...Inverto Twin black pro. C120 H S/85 Q/100
V S/59 Q/0 No lock

And then without the Feed horn.... the following LNB's
Invacom quad Universal.......................................................................H S/90 Q/100
V S/68 Q/3

Smart Titanium Twin.............................................................................H S/89 Q/100
V S/4 Q/0 No lock

Inverto Black Ultimate......................................................................... H S/95 Q/100
V S/78 Q/0 No lock

What is a Black Ultimate? Can you post a picture as I've not heard of that LNB.

Also I don't understand the tests. What frequencies do they correspond to?

These are my strength readings on my Meter. Using my Horizon USB+.. Set on Astra 2a on 28.2....
Sorry that should read Ultra..LOL

On what frequencies? These reports are only helpful if you post the full information. If it is a decent meter it should give readings in SNR or C/N in dB, and frequency in MHz. Readings as a percentage are meaningless.

Hi m8 , where is your location in spain??

 

[radicaldoc]

Hi m8 , where is your location in spain??

The reading are in db and i am south of Jaen near a town called Martos

 

[Huevos]

The reading are in db

Where are the readings in dB? Readings of SNR in dB will be somewhere between 7 and 17.

 

[satelliteman]

Yes, what you have posted is meaningless signal/quality readings.

 

[radicaldoc]

I think maybe the mods should close this thread as all i was trying to do was give people the meter reading of all these LNB's.. Sorry about trying to be helpful.....These are just the Meter readings of my Horizon meter for people to see differences.....
Please close the thread.....

Oh so much for the Black ultra being best there is.... It isn't here....

 

[Captain Jack]

Radical, don't think that your posts are not appreciated. To be honest, I was confused about how the LNB comparison chart was presented. It just mentions H/V with no frequencies. And all H lines have a quality of 100.

I found Black Ultra to be the best LNB in my many tests across many dishes. Granted, none were on the 1.8m (I think a feedhorn + C120 LNB is better here but opinion varies), on various 80cm, 1m and 1.2m dishes, the BU LNB outperformed all of the competition. I even had one converted for me so I could use it on my Fibo, which only accepts C120 LNBs - http://www.satellites.co.uk/forums/topic/155379-project-fibo/page-5#entry830873

All i was trying to show was the Signal strengths on my meter for Astra 2a Horizontal and vertical as here in Spain we are having many problem since the change and especially on the vertical which is where Ch4 HD and Seven4.. It is nothing to do with frequencies only the signal strength of each one on my Channel Master 1.8 Dish
So people could see the difference in each LNB here should someone else be considering buying any.....
So now i have to decide whether i should go to the trouble of chopping up my Ultra and making it a C120 Flange LNB it would mean chopping up my Black ultra and my Black Pro for the flange....

...it would mean chopping up my Black ultra and my Black Pro for the flange...

Next project perhaps?

Without frequency and dB your tests don't relate to anything. Signal strength is different on every transponder so if you don't post what transponder you are testing how can the tests be understood. The Black Ultra is a top performer in Band D (Astra 1N) and Band C (Astra 2F). These are the only important parts of the spectrum for UK PSB channels. If you are testing in another part of the band you may find other LNB/feedhorn combinations out perform the Black Ultra, but in this part of Ku band I very much doubt it.

I don't know a lot but what i do know is your hypothesis is not correct. I know for sure that what I have seen with my meter and my Sat box says that the BU is not the best LNB for Astra 2F Here BU won't lock on the vertical and shows no signal on by box at all so I cannot therefore get CH4 HD or Seven4 which is 2F (right or wrong?) And those two are on the vertical So as far as i am concerned BU is of no use to me here Unless I try it with a Feed Horn and see what happens there. Maybe then it will show better results but not in its native form..

So you are wrong in the assumption you doubt it will be beaten it has been here by the humble Invacom twin (this is the one that everyone said was inferior to the quad again it isn't here)

I can only go on what My meter shows me and what is happening on my Humax Foxsat..... I don't know a lot but what i do know is your hypothesis is not correct.

As I said i don't profess to be an "Expert" like you. These are just my findings on my dish in my situation.......

 

[joddle]

If you cant get a decent signal with the BU then don't use it BUT it seems odd that you can't. I have witnessed Huevos's comments over a good length of time and I am pretty sure he knows what is what. I think you may be wise to ask him (or others) if there is a possible reason why your setup with the BU seems not to be performing so well - perhaps there is a factor you have not thought of!

 

[PaulR]

In have seen reports that Black Ultras have more variability with manufacture than Invacoms do. It may be that you have a "Friday afternoon" LNB.

They are pretty good normally though.

 

[Huevos]

a possible reason why your setup with the BU seems not to be performing so well

LNB depth (distance between LNB and dish) needs adjustment maybe. With the CM feedhorn this is built in to the design, with the BU fine adjustment is needed.

 

[Huevos]

I don't recall putting myself forward as an expert in this or any other thread.

 

[radicaldoc]

I have done all that with all of them except the feed horn LNB's which is a fixed focal length. I think i have tried everything..Focal length,Skew, Dish is bang on that one thing about the CM 1.8 and this mount it's excellent to set...........
As for the expert remark that was a compliment you appear to be the "Expert" here obviously worded wrongly. I definitely am not I have been installing dishes for a good few years Both in the UK and Spain..(although for the last five years only for myself) But I am not a Techy guy as far as Satellites Go. Computers or networking or even Car Truck or Bike mechanic Yes....
I don't put my Ideas here as i am not up to that i only say what i see. As you can see from my posting of the meter figures that everyone got wound up about. But ALL of this is speculative not just here but all the other forums I have been told that BU are god's gift and that Invacom twin is much worse the the quad for some reason then someone else saying that this us untrue. that the Inverto LNB's are better when I tested them on this system none of this was true for me as i said its all down to your system and your set-up and where you are no more no less. As i said this is on other forums as well not just here.......
I have even been told by some tech dept that the CM feed horn you could mess around with the focal length if you don't fit collar as it should go and that was what i should do...
Give me a break......... :-hide

_{Lots of people on this and other fora spout their opinions about all sorts of things - sometimes these are misguided and sometimes very usefull - it all depends on what you want to know and what you read into it. Like in any discussion, people have differing optinions, levels of knowledge and may even change their own stances on matters over time. People must in an ideal world read things as the writer intended - but as we dont know many of the people it is hard to judge the inferences/mood behind the comments being made - and I fear sometimes we get it wrong. Its something we all need to be aware of.}

_{Regards the Invacoms, I do have some experience having owned several over the past 10 years. To my mind there is little if any real difference between the dual and the quad per say BUT there can be quite significant differences between the ports on the same LNB - and on the quad these are more noticabale maybe because there are simply more ports However I have not seen evidence for which ports are better - some say the inner ones are better than the outers but on my current LNB port 1 and 3 are the best and ports 2 and 4 very slighty worse - but not enough to affect my viewing.}
