Setup of a Geosat Pro C2

[rikoski]

I'm trying to set up a dedicated 6' mesh dish for the C band side of I9 at 58 degrees.

(I think that I have found a spot in my tree cover which has a shot at this satellite).

I'm trying to do several things simultaneously: find the satellite (trusting my surveying equipment and pre-tuned Traxis 3500); and getting my Geosat Pro C2 to work.

I don't have instructions for the Geosat, so I'm not sure about how to dc power it. Here are my questions: Looking at the F connectors with the flat plate immediately above the connectors: call the F connectors #1 at the left; and #2 at the right respectively: Can I draw signals from both simultaneously? What dc bias voltage is applied to the left connector; What dc bias is applied to the right? Can I apply bias voltages to each simultaneously or must one always be passive?

Thanks for your help.

yes you can use both ports
both ports draw the same depending on which polarity you are using

also skew on the C2 is different. Line up the 0 with either 9:00 or 3:00 when you start and then go from there. If you line 0 at the top then polarity will be backwards

Thanks. One output will tune vertical polarity; the other horizontal; yes? So I can simply connect two FTA receivers; one to each with both coaxes powered?

Sounds like this lnbf splits the signals somehow into vertical and horizontal sides and has two separate RF amplifier; converter and IF amplifier chains after the split.

So both outputs work independently of each other; yes?

Thanks.

Yes, both outputs are independent of each other, and you can get horizontal and vertical off of each output.

Basically 2 LNBs in one housing.

 

[Mr Tony]

yes each output works independently

use one output for one receiver
use both for 2...each can tune either H or V
for more than 2 add a 2x4 or 3x4 multiswitch

 

[rikoski]

...each can tune either H or V...

Is this by dc level on the respective coax?

If so, then 15VDC for one polarity and 18VDC for the other?

Thanks.

12 - 14VDC = Vertical

16 - 20VDC = Horizontal

Okay... Got it. I should be good to go.

I'll report back later on my experiences from Indiana with this feedhorn on I9 using a 6' dish.

Thanks everyone.

I've used that same LNB on a 6 foot solid dish and works really well at IS9 (58W)

lots of strong signals
