Invacom QPH-031 is considered the Cadillac of LNB’s in the FTA hobby! There are the great Pros of this LNB as noted here and they work for most people and they swear by them!
I love mine, been up for almost three years now and I too have a couple more spares.
My opinion may be biased based on the fact that I use them and that is what is on my main system but there are things I don’t like about it as well.
B~man Cons: :down
A bit heavy
Be nice if it had Universal capabilities with the Standard & Circular
Long top to bottom, nice if the connections were out the back well to me at least
AcWxRadar:I robbed the side "struts" off my 1M Winegard DS-3100 dish and retrofitted them to the 76 cm Winegard DS-2076. That kept the weight of the QPH-031 from sagging the LNBF support bracket.
I did the same with mine, took them off my 3ABN dish and retrofitted the "struts" on my 80 CM Fortec Star.

This LNB would be great for most people with respectable receiving latitudes but not all of us have that perfect receiving spot.
If you are in a lower elevation I would pass on it for it would be overkill for you and the cheaper one Invacom
SNH-031 just might be better in the long run.
Sometimes I have read that the really cheep ones out perform this big boy depending on you location!!
It is all what you want to pay for, where you are at and what kind of dish you want to put it on, by far for me, it has been the best one I have used so far.
The best Just Linear I have used has been the
Fortec Star FSKU-K Single Universal Ku Band LNBF! The one I have has a Noise Figure of 0.3 dB. It is one of the older ones!
The worst I have used is the
Digiwave DGL1189S!
FTABman0: There is a eye catching Invacom kind of claim copy that is cheaper and I might add also it is not really a copy but a cheap LNB that does Circular & Linear Combo & a Dual LNBF and one could sway to it to save money and why not, it does the same thing the Invacom QPH-031 does right?
Absolutely not! Read on!
They have a
DGL1189D which is the same thing (how it goes on the dish tubes). I bought one of these thinking it was just like the Invacom QPH-031 and would be a great cheap replacement one if I needed it to replace the
QPH-031 or better signal improvement over the stock one on my E* dish for subscription, either way I could get it to work on one or the other.
I have tried it on my E* subscribed dish to see if it does better than the OEM LNB and the answer is
NO!
Stay with your DISH LNB!
So I tried FTA use,
defiantly not!!
Don’t waste your money on it! The
Digiwave claims Circular & Linear Combo Dual LNBF but this thing is a paper weight! You can pick them up just about everywhere mostly for about twenty bucks but save your money,
JUNK FOR FTA USE!
They are more so designed for Subscription use hence putting it on a Subscribe Dish of choice, I might add a poor one at that, it suffered by comparison to the standard one that came on the dish! They have the standard DBS dish mounts on the tube for the D type and Square Type. Knowing that it takes a bit of rigging to get them on a FTA throat mounted dish and if you do so, it will not work properly! Steer away from this, it sounds tempting, a cost effective idea opposed to the Invacom
QPH-031 but not designed for the FTA Market!
Here are the specs (From The Web) of the
DIGIWAVE:
DIGIWAVE DGL-1189S & DGL-1189D
Circular & Linear Combo Dual LNBF
Use only one LNB to receive signals from 119 and 118.8 Satellites
KU Band Universal Linear & Circular Dual output LNB with Dual polarization.
Works for all circular satellites, i.e. EchoStar 3 (Dish Network 61.5), Echostar 6/8 (Dish network 110), Echostar 7 (Dish network 119 &118.8), EchoStar 1/2 (Dish Network 148), All DirecTV, All Bell ExpressVu and other Circular Polarity satellites.
Specially designed for catching 119 (Echo 7) & 118.8 (Anik F3) at the same time using one such LNB.
It also catches linear satellites; plus one output gets both circular and linear signal. It also works for Dish 500 and Super Dish.
It works with most Echostar 300, 500, Super Dish and others.
Dual Output LNBF
Input Frequency Range from 10.70 GHz ~ 12.75 GHz
Output Frequency Range from 950 MHz ~ 2150 MHz
L.O.: 9.75GHz and 10.60 GHz
Low Phase Noise for Analog or Digital reception
Excellent D.R.O. stability
Noise Figure: 0.5dB (typ.)
Was not happy with the testing of this LNB and
IS NOT a good replacement decision or does not even compare to the Invacom
QPH-031!
