Have recently had a 1.4m motorized dish installed in Southern Portugal.
I am just about able to pick-up Astra 2 (28.5E), but only the Horizontal transponders. Vertical transponders just about shows through on the quality bar, but the signal is not strong enough for the receiver to lock on.
Has this something to do with the skew of the LNB?
Would a low noise LNB improve this? (currently using a quad 0.3dB, but quad 0.1dB LNBs are now available).
Would it be worth my while investing in a new LNB? If so, which of these quad LNBs is the best:
Titanium, Technomate or Icecrypt?
Any ideas?
Advice more than welcome.

The much better investment would be a larger dish 1.8 - 2m in Southern Portugal is still close to the edge. based on the Astra 2D 28.2E satellite footprint. If you have a dish 1.4m or smaller in Portugal, it is advisable to use a Freesat card with East Midlands or Tyne Tees as the default region on BBC1and ITV1. This region comes through much more reliably than other regions such as London or North-West.
So a lower noise LNB would make very little improvement.

Sorry I should have said I upgraded from a 1.4m dish to a motorized 1.6m Gibertini dish, so the dish size should be OK - the 1.4m fixed dish picked up Astra 2 reasonably well, so I added 0.2m to compensate for the motorized system's movements.
I was kind of interested in some feedback on the LNB questions.
Any ideas which is the best to go for? It has to be a quad lnb.

I would go for Inverto ultra black m8, 0.01db gives you at least 20% more signal @ http://www.google.co.uk/aclk?sa=l&ai=CyKuZpFm0TfmHH4Kc8AOgkcmIAYmsl tsB2Y7H-heh262CPggAEAIgtlQoA1Ck2J-R-_____8BYLvum4PQCqAB3ZSv8APIAQGpAl OjCXQjtbs-qgQeT9D4vfh_41Cshl60AACF6Eaa4Scz3 KkwtJ_xdLZ3gAWQTg&sig=AGiWqtzzhS6Av7zWClV4ds80kJ3mn O1mCw&ved=0CBQQ0Qw&adurl=http://www.aerialshack.com/inverto-m-35.html&rct=j&q=inverto%20ultra%20black%20lnb&cad=rja The best on the market but not cheap.

The Invocom Universal Quatro LNB 0.3dB Horn (QDH-031 ) and the Universal Quatro LNB 0.3dB C120. (QDF-031 ) are also very good.

Found the same LNB on e-bay for almost half the price. What do you recon, could it be a counterfeit?

I bought two of these last November one from a well respected wholesaler there last one, and because I had to have the two, the other one was ordered from your link, and the both were identical, and that included the performance, on a ******** analyser.

I donīt know why it has to be quad, but I know that single type LNBs have stronger signal than others. Regarding the price - it should not be a problem. No LNB costs so much you cannot afford it.

Have been using a black ultra (not black premium) for some time and it's the best of many used over the years.

I can say is I have 2 dishes, both channel master one 1.2m other 1.8m.
Over the last 15 years i have played with many LNBs feedhorn etc.
I must have ove 10 spare sitting in a draw, some for the feed horn for my dishes some standard, wich i use these days.
I have never got more than a 3-5% increase for changeing from 0.7 to 0.3 to 0.1 these days, I have spent at top end and bottom end both have produced equally and lasted as well.
So, if you do change your lnb dont waste you money on exspensive you wont see a difference, if you are on the limit, ie, for me 7w on the 1.2m the only solution is a bigger dish, lnb changes are so small the weather has a bigger effect.

As great dane said, He has already upgraded his dish to 1.6 Glbertini excellent choice so why not have the best Lnb to suit.

Well my Inverto ultra black twin arrived yesterday and was installed today, it is about a 15/20% improvement on signal strength compared with the Smart Titanium Twin output LNB that I bought last year. I haven't had time to play too much but I definiely found that it needed to be slid as far away from the dish as possible to get the best signal. I might get my full range of stellites back again now, I'm much happier.
