Re: Signal differences between LNB's

Out of all those that are listed the best one to buy would be the Inverto twin Black Ultra it will outperform the others with ease

Re: Signal differences between LNB's

Hello

Of course using a good quality lnb you can increase the signal.
Inverto lnb is a very good lnb, but remember that this isn't the only factor that can influence the reception.
For example, a good quality cable is a major factor for a good reception, as well as the quality of the sat dish.

Re: Signal differences between LNB's

how many percent increases signal level expensive LNB compared with the budget inexpensive LNB

**rizwan** · 10-23-2013, 08:03 AM

Re: Signal differences between LNB's

Also consider, how much it cost to Increase the Dish Size, Bigger dish reflect more signals

Re: Signal differences between LNB's

The Inverto black ultra range would be the best ones to go for, there are a number of things which affect the performance of the LNB and the .1db you see bandied about do not mean very much unless you get some reference to work from, gain relative to noise and also the frequency that this figure was measured at. Invest in some decent Lnb's, you will not be disappointed, but, as has been mentioned decent quality cable and time spent setting the whole lot up will also help. A bigger dish will never go amiss either.

Re: Signal differences between LNB's

dear mmoloch

a very good lnb in terms of perfomance will give a signal free of pixelations when at the same conditions another less perfoming will not open the same channel on same reception conditions partially or at all.

but do not expect dramatic changes only marginal signal thresholds can make difference.

always the most important factor (without underestimating lnb cables accurate alignment etc) is a bigger dish for more demanding receptions

Re: Signal differences between LNB's

This topic is related to this one: http://www.satlover.eu/forum/install...-strength.html

I installed a new dish with a motor diseqc 1.2 and lost 12% signal strength and started to have some problems in DVB-S2 transponders. The cable I'm using is RG6 ITED of Iberosat, I know that is not a top quality cable but I think it is a relatively good cable.

My system:

Dish 1 - 60cm, Hispasat 30�W

Dish 2 - 85cm, Astra1 19.2�E in the center ; Hotbird 13�E ; Astra4 4.8�E ; Astra3 23.5�E ; Astra2 28.2�E

Dish 3 - 125cm, motor diseqc 1.2, catch all satellites with coverage in Portugal between 39�E and 34.5�W

When I installed the motor started to have some problems in the dish 2, three DVB-S2 transponders from Hotbird began to fail, the signal quality is always going from 100% to 0%, I've tried changing the LNB skew and changing the position of the LNB but still fail.

In dish 2 also had problems on Astra2 28.2�E, this LNB was to watch just 20 channels from 28.2�E, before 15 of the 20 channels had 75% of signal strength and 100% of quality, now have 62% strength and 80% quality, I can watch them without problems but 5 of these channels before had 70% strength and 70% quality and now have 56% strength and 50% quality and are always failing.

The dish with motor all sats have several transponders with maximum signal but in all of them there are some transponders missing, transponders that I know I should get in my location with a 125cm dish. I'm out of Astra 2A North footprint and I have signal in almost all transponders, 60% strength and 50% quality but the channels are always failing.

For now I'm thinking of buying only 3 good LNB's because I'm having problems only with 3 LNB's, Hotbird, Astra2 and motorized LNB.

I'll buy two Inverto Black Ultra Twin but also need a quad LNB and I've read that the Inverto Black Ultra Quad is disappointing, is it true?... should I choose another quad model or brand?

Re: Signal differences between LNB's

I've always found the MTI range and the Inverto range of LNB's to be very good (dare say the best), never tried the Inverto Quad but heard the same bad things (In the sense its not as good as their single or twin), but you prob find it the same with all quads, by design 4 squeezed into the same headend receiving space as 1 or two, isn't going to be as good (despite the fact quads operate differently ie a separate feed for Low/High Band & Horizontal & Vertical, so you can connect multi receivers). So if it was me I would prob still get either an Inverto or MTI quad........

Just to clear up a common mistake,you are confusing Quad Band Lnb's with Quatro Band ones, a Quad band is simply that, 4 single outputs, whereas a Quatro Lnb has separate High/Low & H/V switching, Usually the problem with a Quad band Lnb is that the 4 outputs do not have equal performance.

Re: Signal differences between LNB's

It is better to buy larger cheap dish and cheap LNB then more expensive but smaller.

Because you can buy regular good LNB for 10$, and then use rest of the money to buy larger dish.
But if you whant best LNB then probably it is Inverto Black Ultra

Re: Signal differences between LNB's

a plate 120 is faster and reliable at the time to locate satellites, but also occupies more space and leave many communities place

Re: Signal differences between LNB's

Maybe you should try a wavefrontier dish with a 1.1 switch instead of a big motorized dish.
A motorized dish has to be exactly aligned where a wavefrontier is less sensitive. Add the movement deviation and the movement because of the wind and weak transponders are gone.

**rizwan** · 10-30-2013, 07:31 PM

Re: Signal differences between LNB's

A good LNB make some difference on Weak Transponders, but increase in Dish size make much

Actualy it is quite easy to setup motorized dish. You just need to know your latitude and longitude, and what is your primary satellite.
First time I done motorized dish it was perfect i can get from 45E to 30W and I didnt try any more.
