Does anyone here have a Motorized Dish
system Using the Invacom QPH-031 and a Digiwave DGL 1189S LNB?
I can't seem to scan in all the channels on Anik F3. Iam using this bracket for the Digiwave LNB.

If you have a QPH-031 you dont need a DGL 1189S LNB.

I have a motorized 33" dish and a QPH-031
This LNB get a stronger signal than Digiwave

Thanks plymouth
But not the answer I was looking for.
I have visted other sites and all are saying the same thing the QPH-031
will not work on Anik F3. I have tried it using only the QPH-031 I did picked up one tp. Maybe you didn't understand my question. I have attached the
DGL 1189S with the bracket as I have posted above I scan in most of the channels on Anik F3 but not all.

I was hoping to find someone that has tested this type of installation
using a Invacom QPH-031 and the special
LNB for Anik F3 attached adjacent to the QPH-031 and tell me what am I doing wrong

Give me one good reason why it not work.
It not work if you try 0n 119 but try with 118,8 in Circular mode LNB freq 10750, do a blind scan.
Which receiver you use for it?
I use Viewsat Ultra and it work!

If you want use digiwave go in satellite menu and modify 119 sat for 109 and turn your bracket for put the LNB as near is possible of QPH-031.
But this solution is a patch, surely you can lose signal because this dish give a stronger signal directly on its holder.

In clear term if you fit a second LNB, this LNB cant be in the best Axis and you surely lost signal strenght.

Which receiver you use with this dish?

You mean to tell me that just by adding
a second LNB you would lose signal power?

How much signal strenght do you think this guy lost?

I cant say you, because i dont try it.

Can you give me the receiver Model?
Because QPH-031 not work fine on all receivers.

Yo should be able to add a second LNB and assign to DISEqC port
First LNB can be set to DISEqC 1.2 or USAL
Second LNB set to DISEqC 1.1 or 1.0 port-2
If yor FTA receiver supports DISEqC all protocol

Another way to do it using 22K SW
Yo turn OFF tone to Invacom ON to the other LNB

Re: Anik 3 118.8W..Can I get it?

--------------------------------------------------------------------------------



In North America:
Circular polarity Ku sats use TP Freqs 12200 to 12700
Linear polarity Ku sats use TP Freqs 11700 to 12200

This is what your QPH-031 LNB is setup for.

DN's new 118w sat is the only one of its kind, and DN had to come out with a totally new LNB to use this sat.
118w uses circular polarity BUT linear TP Freqs 11700 to 12200.

So on your QPH-031 LNB you would use an "L" port to "see" this TP range but because its circular polarity the "L" LNB can not get all the TPs.

You need a special LNB just for this one sat, there is no "one LNB" that can get all sats now, no matter what you see advertised, lol, the invacom QPH-031 could get all sats before 118w was launched.

The CB2008 LNB is circular polarity and can "see" linear TP Freqs, as well as the DN 118/119 combo LNB found on the dish500+ and dish1000+ setups.
Some put up a separate dish just for 118w, others add the CB2008 LNB next to their QPH-031.

After many test and research, i can say to you""""You are right""""
I cant get all Tp on 118.75W.
I tested the circular 10750 lnb(friend) and get all Tp.
You give me a good reason for buying one.
I always thinking that is because i am far.
Sorry

It work on side of the QPH-031


Here is the picture of installation

I have made a bracket in solid plastic and s.s. bolt

Upload

I changed the degree in Motor Usals 118.7W for 107.2 in accord with the space btw 2 LNBs

I don't agree about Circular or Linear LNBs
It's a combination between frequency and gain
Is the main reason can't get all TPs

LNBF has an internal orthogonal antenna
And antenna is just an antenna
Limited by the frequency span and amplification gain
Where yo live and size of dish is another factor
Circular polarity comes spinning it doesn't require skewing
Linear polarity must be tilted to face orthogonal polarity
2 wires
One Vertical, other Horizontal
Circular polarity is still Vertical and Hrizontal polarities

Yo always gonna have variance from one LNB to another
It even differs from one receiver to another based on yor tuner capability

Just for the record
King Arthur c/p is an echo to what I said in many different threads
Finally members beginning to understand it
What I'm saying here people will repeat in different forums and at the end is gonna echo back on this forum
I spent my life on Data Communication electronics
It's not much different from Telecommunication electronics
Basics are the same

So believe me when I say
Circular or Linear no major difference
Only frequency and gain and quality of LNB makes the difference

The QPH-031 is a great LNB, but the manufacturer only need to upgrade the frequency for get 118.7

note, only 118.7 is a problem.

The BSC621 cant receive circular and linear in same time, because we need to install a dielectric plate inside.

Next dish i buy is a big one with C-Band LNB, i try to buy it worn(i dont know if it is the good word)second hand.

C-Band, 1.2 meter C/Ku LNB
That's my next hobby next year when PTA turns cold
There is a great possibility PTA can turn to C-band next year

Just a possibility
