I replaced my rg-6 cable from dish to the house with rg-11 quad shield cable, and here are the results.
I was hoping to make a bigger difference on the system, but it don't seem to have been worth the money.

Before;
SNR: 7.6 dB
Cable Attenuation 5.4 dB
Cable Resistance 2.0 Ohm
Rx Power: -48.0dBm
ODU Telemetry status Active
TRIA status is Tx RF Power:30.6 dBm

After:
Rx Power: -43.9dBm
Cable Attenuation5.5 dB
Cable Resistance1.5Ohm
Rx SNR: 8.0dB
ODU Telemetry status Active 
Tria Status is Tx RF Power: 30.6 dBm


Any input on this is always welcome.

Dave

The Only Factor REPLACING The Cable Would CHANGE Is The ohms. You were at 2 ohms and after replacement it came down to 1.5ohm. Not a big difference. Exede allows upto 5ohms before they send a tech out. 1ohm is the lowest I have ever seen. Your signal strength depends on the alignment of the dish and any obstricles in the way. is the trial at the end of your dish about 9 inches long or is it short with a chrome looking backside?

FWIW, mine has shown a constant .5 Ohm...

Yeah, my cable resistance is consistently at 0.5, but on summer days when my TRIA reaches +70°C it bumps up to 1.0 Ohm.

Actually, the copper covered steel center conductor of the RG-11 has more resistance than the solid copper center of a Viasat approved RG-6.  I guess the more massive shield of the RG-11 helped out in this case.

I would say it was at least 9" long. DOes that make a difference? And why would you ask that question?

Whether u have the Legacy Tria or the new eTria. The legacy tria is about 9 inches long and heavy. It seems that the new eTria gets a little better dB than the legacy tria. That's just my opinion from experience. All cabling has to have a solid copper center conductor in order to be via sat approved.

also, you may not want to here this but if Exede sends a tech out for any reason and u have rg11 cabling, they are going to want to replace it because none of use have and compression connectors for rg11 and it's not Exede approved. In theory one would think it would work better than rg6 but via sat says it doesn't make a big enough difference in quality to have it approved and make techs care rg6, and rg11 equipment.

Well this was only an experiment to satisfy my thought of a better cable meaning less loss from the dish. But as I said and someone else said its not worth it. Cause when we have even a light rain here my modem looses signal and I am down for a while. No sense in calling and reporting it cause it always come back within a hour or less. Maybe I need a bigger dish for more gain!!!!!! Looking for a 6ft spun aluminum dish and mount... :-)

I have done some reading online a while back on coax and for the short distance your running (under 100ft) the cable won't make that much of a difference. Now at the higher ferquences like 2Ghz or higher the better shielding will prevent signal loss more then say just a standard double shielded cable. Have even see very high end cable online that has a solid coper shield and even at 300 feet the signal loss is only like 5db

You have some other problems, probably dish pointing. It does take pretty much a frog stranger before mine goes out and I have a 150" of cable.

As predicted, but I'm glad to see a real world experiment following theory.  At least you know you did get a good piece of RG-11.

Me too.  Years ago I put a 36" dish on my DirecTV.  It would take a real frog strangler to cause rain fade.

HighesNet actually has a bigger dish then exede so will be interesting to see the difference when the weather gets bad

just curious, did you terminate the RG-11 yourself?

No I didn't, I got it today and all I did was Ohm it out and make sure I wasn't open or shorted.

Blessed are the geeks, for they will inherit the earth. (That's how it goes, right?)

I love these posts! Thanks for all the great responses.

OK I just put the original RG-6 messenger cable back on. There was no performance difference that I could see with what I have. I did a speed test and got this from http://speedtest.tds.net/ :

Before I changed the cable ..

So in conclusion the cable that came with the Install performed better than the new I bought. Not that the cable I bought was bad, but rather it didn't prove better at the length of 75 ft. The we have to look at the way the system was tuned with the RG-6.  I am sure that lengths of cable longer than 150 ft. that the RG-11 would shine over the RG-6.

I want to thank everyone for there comments and suggestions during the last week.

May the Lord take a liken to ya and until the next time.

PS. anyone need some slightly used RG-11 quad shield...lol

More food for thought David, wonder if you had SC (solid copper) rg-11 vs CCS (copper covered steel) only reason I say that is I also read that with the CCS the signal bounces around on the coating rather then using the full wire.

PS not that I'm trying to get you to have more "slightly used rg-11" :)
