Looking for twin or more Lnb to work with channel master 1.2 dish
Any recommendations please
hi m8 yes i bought some new lnb,s few weeks back.
i got the following black inverto ultra twin,golden media 202 twin lnb and bought a 2nd one for barney on here and he is well impressed with it and he has it on a cm 1.2m
Golden media 202 twin lnb :respect-039:
Barney, where did you buy this LNB from ? How much ? And is it C120 ?
Ian.
Butchyboy sent it to me , Under £15 use google search , No its not C120 .
but you can use a C120 LNB its just signal is very hard to focus on an offset 1.2m dish .
i find the GM LNB very good gain is so much better it performs really well locking a lot of low signal feeds
where the IBU LNB and so many others would drop signal via rain and weather the GM LNB keeps a good lock
it is very impressive on 42E S Sport and really good for any occasional 28E Feeds ,
give a good solid signal on 1W where every other LNB that i tested would fail so badly , its really cheap and does a much better job than other much more expensive LNB's .
Thanks Lads just ordered oneQuote:

Ian.
PLL should out perform Dro, its just hard finding a quality PLL. Looks like this Golden media 202 might be it. Ive just bought the single output. lets see how it goes
This is my LNB holder just may require longer screws but it does work just fine .

Yes I consdered longer screws but I came to the conclusion that because the LNB wont sit properly in the bottom part of the holder simply because its to large, then the focal point would be raised by at least 20mm, probably more. Surely this results in signal loss ?
Mines different to that too, mines metal.
Ian.
Same as mineQuote:

This is my dish and mount that someones selling.
I'm not a member of that site though so i cannot download the image which shows the LNB holder. If someone is a member perhaps they can grab it, but even from the picture shown you can see that its unlikely a 40mm collar LNB is going to ever fit.Code:https://www.satellites.co.uk/forums/threads/echostar-1-2m-dish-polar-head-ground-stand.161671/
Ian.
There are 2 pictures, of the dish face, in your link:

@Ian if that holder is original Cm or copy it will be 40 mm core , you would then need the spacers to fit the cm feedhorn 20mm , does yours use the spacers ? if not they say its the same as the cm so the one listed above will fit youre dish and 40 mm collar lnb.
Hope i made a bit of sense
there :D
@ian just seen the photos its not like a channel master so ignore my post above.
That dish does look like another cant think what thou at the moment .
Yes I think that dish is smaller than mine and mine doesnt have the red Echostar writing, although I do believe it is an Echostar. But if you download the pic then make it bigger you can clearly see the metal holder, which is identical to mine and that I dont think its possible to fit a 40mm collar LNB into it. Such as shame because £15 for a good quality LNB is very good value, especially as so many are saying it gives great results.
Ian.
@ian can you add photos a few angles of youre lnb holder off youre dish ?
I can try, but my camera lens on my phone is cracked and the images come out pretty blury.
Ian.
You need a new phone as well as a new lnb :D
You can zoom in and see my LNB Holder much different on my Channel Master 1.2m dish
you can see the Golden Media LNB Fits without any issue whatsoever : )
dish is fairly old and has the old original Channel Master Logo still on it i believe ??
LNB Holder can accept a Feed horn with using the small black plastic spacers that usually are provided with a CM Feedhorn .
Yes sadly mines very different to that.
Your very lucky Barney. It seems that your dish caters for both 20mm and 40mm colars.
I wonder if its possible to buy the arms and the holder that you have and fit them to my dish ?
Probably not though as mine attach to the dish by means of self tapper screws, which screw into the very outside edge of the dish, so more signal is gained as the arms are not blocking the very outside dish area like yours do. Although what is gained by this is probably nominal.
From your pictures your arms seems to be attached differently. I cant quite make out how. Possibly through holes in the dish itself ?
Ian.
Best my scratched camera lens can do.
You have to remember my dish is now 35 years old and 40mm collars hadnt even been invented, it was originally was ran from a Chaparral Cheyenne ( I couldnt afford the Monterey ) and shortly after upgraded to an Echostar 5500.
I bought it back in 1987 when Sky was just one channel broadcasting from an Intelsat craft for just 2 hours a day.
Ian.
Ps Do you like my coffee jar lid acting as a feedhorn cover lol ? I'm afraid 35 years of sunlight made the original plastic one very brittle and it just fell apart.
As you can see though theres no way its going to take a 40mm collar LNB as it is right now.
You sure the camera isn't 35 years old too ?Quote:

This is a photo of the goldenmedia with plastic covers removed , i recon that neck is pretty close to 20 mm , if youre not worried about the look just fit it with the plastic covers removed .
just fit the feedhorn cover back on same way as you done with the jamjar lid .
Ok thats excellent Cossie. Cheers buddy.
I shall be getting one of those then. Considering C120's are hundreds of pounds and probably not as good either. Just needs to be seeled properly as its exposed to the ellements, but I would imagine it is.
I would never have thought of trying to remove the covers lol.
So where did you guys purchase yours from ? Do Goldwafers have them ?
It is just a tenner on A-m-a-z-o-n but I would like to get it from Goldwafers if possible.
Ian.
Just looked on Goldwafers and it appears that they dont stock them. Shame.
Christ I cannot believe how cheap LNB's are now, well none C120's anyway. The last one I bought I'm sure I paid over £100 for it, but again it was a C120 which are a rip off.
Ian.
ian check your messages m8 :)
Bought one for £9.99 with free delivery.
But it wont arrive till between Wednesday and Friday next week Grrrrrrrrr
Why does postage take so long ? This is why I detest buying things online.
Ian.
Generally because people like the free postage, if you're willing to pay more, which will double the price, you could have it tomorrow.
i still have my single black inverto ultra on my 1.85m offset dish and have it on 3 yrs now and well happy,but few weeks ago i bought a few lnbs and another single black ultra inverto along with a twin black ultra inverto which be handy for feeding my sat box and feeding my tbs card in my pc and also bought 2 of the golden media 202 twins and one to try out for myself and the other for my good irish friend barney and he tryed it as soon as it arrived and hes over the moon with it,so come a really hot sunny day i shall be trying out all the mentioned lnb,s :) all trial and error etc as to whats best for a dish and location etc etc hope you will be as happy as barney ian :)
Just for clarity for anyone else that stumbles on this thread, is it the GM 202 or the GM 202+ (high gain version) that is being recommended ?
The older Golden Media GM 202 is now redundant and near impossible to find .
The New Golden Media GM 202+ High Gain version LNB is what we are talking about here i have both versions ,
the older GM LNB was very good but failed to perform very well under wet conditions this has been improved and resolved with the new version and does provide solid signals especially with 42E and the weaker 28E Football feeds which i struggled with very hard with every other LNB that i have tested .
cheers !
Raising the LNB 20mm won't change the signal strength significantly on an offset focus dish but you would need to point the dish a fraction higher to compensate.Quote:

@ Detlef i'm not sure you are correct on that point , the dishes focal point will always be the same , raising or lowering it etc would help but only to get part of the signal from the dish face there.Quote:

when its for feed reception it matters though, for regular broadcasts you can be way off and still get a signalQuote:

i think ian will have a big shock with the new lnb ,looks like Fred flintstone use to run one of them back in the day :D
