Best setup possible for 4.2 prime focus (expats of cyprus and not only)

[washoris]

Dear all again,

I started a new topic since this is something completely different. After many discussions i had with @solly he made me curious if with the setup i have now its the most i can get out of it. For example if my feedhorn is right or i need a bigger one to take advantage of the whole dish. Is there an lnb with higher db power than invacom?? And what about my feedhorn?? I see many people having something like a more wide metal at the end than mine (bigger diameter) what's the difference? And how can someone get benefits from a more wide feedhorn??

2 months ago i got scammed by a Chinese guy that told me that these lnbs over here http://www.alibaba.com/product-detail/super-gain-70db-ku-band-lnb_787369263.html are the best performers and should get me more signal than any lnb on my prime focus. I tested them and the signal i was getting was ridiculously low. He then said that these lnbs should be used on mesh dishes of 1.80. This didn't make sense to me but anyways.

Is there anything that can benefit anyone with that large dishes? to get that extra bit of signal needed in order to receive more channels??

For example how is this feedhorn http://www.satellitesuperstore.com/images/cmfeed.jpg any better than mine?

Thanks to all of you!

...Is there an lnb with higher db power than invacom??...

Higher dB power output means that you have longer cable from LNC to receiver.And x-tra power compensate this.
I think you want samthing with lower noise figure,for fringe areas.Here in the east Inverto Black Ultra twin it s the best.Other think the best results about DX-ing comes from Inverto White twin.Depends in what year LNC was manufactured.I think.This items perform better then Invacom.

And what about my feedhorn?? I see many people having something like a more wide metal at the end than mine (bigger diameter) what's the difference? And how can someone get benefits from a more wide feedhorn??

Large scalar rings it s useful when dish shape it s not perfect,make some shf corections.Sometime it s useful,sometime it s not.Depends what problem have your antenna.Nothing and nobody it s perfect.

Stay away from 0,1-0,2 NF in the future.It s scam.Same from LNC-HD.

Good!! Is there a comparison between black ultra converted and invacom?? Most of which i found on net show that invacom is better:/
