Invacom TWF-031

[Costactc]

I have been having a hell of a time trying to find a dual universal prime focus lnbf for my 8' solid and EB suggested invacom. Unfortunately, I couldn't find any North American dealer that has it in stock so I purchased one in the UK. This is a flange lnbf which is used in combination with a c120 feed horn. I can't wait to slap this on my dish and maximize signal quality as this lnbf will see all my dish and not partially with the lnbf I'm presently using, which is meant for an offset dish:

Let me know how that one works. I have been looking at the 4 port inverto quad for my comtech dish.

[el bandido]

Not knocking the Inverto brand but we had some of those lnbs to test and they did not work at all. There is going to be bad pieces made in any production run but getting a bad piece like that for testing does not build confidence.
Invacom has treated me well. I have some of their lnbs about a decade old and still running good. We will have to see how these new pieces perform. i plan to be upgrading a 1.8 meter prime focus dish for the Atlantic. It will have similar pieces as Costa, but I too am looking for a quad Universal lnb. Right now, it looks like Invacom for me too.

This is a single output one that is pretty cheap.

[el bandido]

11.70-12.2 GHz, LO 10.75

That cheap LNB is not going to be much good in the Atlantic. Many transponders are below 11.70 for those satellites.

[rrob311]

OK I get it, that one is only for high band. would one that goes from 10.7-12.75 cover everything I need for linear Ku? Or is that still not enough?

[el bandido]

10.7-12.75 Is about the most coverage you can get in a fta ku lnb. Those are the lnbs that we use for the Atlantic satellites.

All you need for North America is a standard 10750 lnb for satellites above 61.0West.

Mail man just came a knocking on the door with my Spring project- get total coverage of my 8' prime focus solid. Just a note that the adjustable c120 feed horn is an invacom. Once installed all ku sats should scan in at 99% signal quality as this lnb is meant for a prime focus dish and the lnb I am using at the moment is for an offset dish. I can't wait for the snow to disappear and the temps to start rising:

The final setup once assembled- Invacom twf-031 universal dual lnb and c120 adjustable feed horn:

No need to wait because there is not any snow here.
Send those parts to me and I will test then for you!

[Costactc]

Thanks for the offer EB but I think I'll pass, I'll just wait until it warms up a bit.

[el bandido]

I just ordered almost the same parts for my 1.8 meter dish. I decided to get the quad QDF-031 lnb. Mine should be installed and running in a couple of weeks.

Damn EB, I have a qdf-031 collecting dust in my garage. If there is any way you can cancel, I'll ship you mine.

Here's a picture of my QPF-021 with the c120 feedhorn and the scalar inverted:

Ok.
I think that is the standard linear/ circular lnb. The quad that I ordered is universal and only linear.

[Costactc]

Correct EB, the one I have is standard linear and circular.

Well mother nature is finally starting to cooperate so it looks as though tomorrow will be install day for my invacom twf-031 prime focus lnbf, supposed to be a bit cooler and possible rain- hopefully I'll be able to get it done with the help of my good neighbour Lexmark. I will be concentrating on 3 satellites- Telstar 12, Amc 6 and Galaxy 23/Echostar 9. I'm going to see what signal quality I'm getting at the moment and do a comparison with the new feed. I'll be using the same positioner outdoors that is already hooked up to this dish so I won't have to rescan and save my satellites after. Some pics outside today:

Not much room for improvement, I broke out my old Pansat 2500 and 3500 but decided on the Linkbox 8000 as I really like its quality meter. Here is what I am attempting to improve on:

Telstar 12-15w

11964 H 14714 85%
11708 V 3197 86%

Hispasat 1c/d/e-30w

11884 V 27500 90%

Amc 6-72w

12055 V 6890 90%

Galaxy 17-91w

12012 V 11574 90%

Echostar 9-121w

12016 V 20000 91%

The Quality Signal reading does not tell us a whole lot because it is a measure of the satellite signal and the noise. Have you got a receiver that runs Enigma 2 firmware? Most Enigma 2 firmwares will show you the signal to noise ration in db?

[Costactc]

Never used enigma 2 on any receiver yet EB.

So if I flash my GM Triplex with this file it will show me db?

Just took out all my equipment and was about to hook up my positioner when mother nature started raining on my parade. It's a balmy 5c(40f) as well, may not happen today but I hope this s*** stops soon.

[Costactc]

Rain finally stopped and the sun is out. Positioner and receiver are all hooked up and ready to go:

Cool. Where is the drink Costa??/

[Costactc]

I haven't removed the scalar ring so we added a round piece of plastic to the throat of then lnb. Signal quality has improved 1-5% on all tp that I had scanned yesterday and we haven't really skewed it yet. My neighbour Lexmark doesn't like the plastic throat so he is modding a more solid piece of wood to put around the throat for better stability:

Mother nature threw some snow, rain and even a few snow pellets at us so we called it a day. Of the six satellites I had scanned yesterday all had an improvement of about 2-3% with Galaxy 17 coming in 5% stronger. The only sat that got worse was Hispasat for some reason, I thought maybe an eastern thing but Telstar 12 has improved. That's all for today folks. I finally have the proper prime focus lnbf for my dish- more to follow once the weather gets better.

Just checked my ku arc and all is more stronger then before, even Hispasat. This was an awesome investment and I'm sure will help with my future scans. Now about the E2 thingy EB, what do I have to do to get it going. I'll start another thread in the appropriate forum.
