Hi Steffen
I have tried it with the Invacom feedhorn,the results were about the same.
i will try to upload the photos,i uploaded them direct from the camera to my laptop,and they are in a matrix of other photos,i am trying to isolate the relevent ones,when i attach it to this reply, it says too much and will not attach.
You can resize the pictures in Office Picture Manager in the MS Office Suite easily.Originally Posted by dave branson
Here is a picture,will try to send more later
More photos of the Smart LNB, I have more if anyone is interested.
You have any picture without the feedhorn attached so we can see how you have attached it to the feed?
With the IRTE feedhorn is just a push in fit to the Smart intregated feedhorn,
bit of super glue and tape.
With the Invacom feed,i removed the matching flange from the Invacom LNB
mated it with the Smart,fixed it with super glue,and bolted the feedhorn back on,its quite easy,you just have to make sure that everything is straight.
You like the IRTE dish?
How do you think it compares to other 1.8M dishes?
To be quite honest,i really dont know after the change from Astra 2a to 2d
by the BBC,i asked a local dealer to install a 2 meter dish,it actually measures
1.954cm,so i natually assumed it to be a 2m dish,only after it was installed and by gaining knowledge on the net,i realised it was a 1.8,the dealer used a footprint of 2d,which indicated 1.8 for this part of Italy,(50klms south of Florence) in Pisa ect,and North of Florence you can receive BBC on a 1.5 dish,
so i was not concerned too much,as i could get it 95% of the time.
It was about 1 year ago the Satellite relocated its position,so at the moment its ok from early morning till early evening,picture quality during this period is 50-55%,after about 21-00 using the Invacom it breaks up on all transponders.
With the Smart,the last couple of evenings about 19-00 it starts to go.
Most likely a bigger dish would do the trick,but the cost is restrictive to replace the existing dish.
Hey Dave!
Haven't you cut the feed off the Titanium before you attached it to the feedhorn?!? The waveguides are supposed to mate with a diameter as close to each other as possible,otherwise you can have a standing wave problem!
I don't say it would get better but I think so.The conversions I have made that way works very well,for example I cut an Interstar GI-201 and mated it with another feed (cd-80),used it on my Gibertini,the increase was 14 % on Astra 2d!!!
Interestig,no i did not cut off the existing smart feed,the 120 flange on the Feedhorn pushed into the first scalar ring of the smart,with atight fit,thought that would be ok.
Likvid sent me a german website,with a picture of an example,i just followed that.
As i have a couple of these smarts,i will cut one up and see what happens then,in the meantime i am thinking of going back to the Invacom route.
Have you thought about going my route?
I use two SMW LNBs and SMW OMT and get really good results compared to the Invacom and MTI LNB i also have.
Willing to try,but i would need your help with how to fix it to the dish ect,
and also where to get one from.
I understand that you have to fit transformers and things which go bump in the night,as they say.
But you have the original Invacom feedhorn right?
Then it is easy to fix, you just screw the OMT to the feed as you did with the LNB you have now.
I would suggest a C120/C120 adapter between the feed and OMT also so you get that sorted out.
Yes i have an Invacom feedhorn,any info/pictures would be appreciated,withregards to adaptors,links to SMW.ect
www.smw.se
I can't tell prices here on the forum as i buy for trade prices.
PM and you get an idea how much this cost.
Here is a setup in Russia using the SMW dual outputs LNBs, but the concept is the same, don't ask me price for those beasts, they cost a fortune.
most likely a daft question,assuming the outputs are low and high with associated cables,do the cables get joined up somewhere,to make one lead
to the end application?
Yes but those are the WDL LNBs for commercial headends, it's not really suited for private use.
The X-Line range is much better suited for that and performs the same really.
Seems like Invacom is better in Western Europe, SMW for the east. The horizontal frequencies are really difficult here in Spain.
Hi Steffen
I cut the feedhorn from the Smart,and attached a 120 c flange,is this what you mean?
That looks better!
It would have been easier to see if it's right if you would have taken a pic from the front(into the hole)as well.Do you have the approx. same diameter from the flange and all the way in the lnb now?
Ther is about 1mm difference in the bore,between the flange and the LNB.
The same as for me then,shouldn't be a problem!Hope this will work better for you.
I will try to set it up asap,and let you know,thanks for the input.
As a matter of interest,does anyone know were you can buy C120 Flanges
