Coax compatabilly with G2+

[wildmanbaker]

I am in the process of replacing the winegard crank-up sat antenna the came with the MH, with a winegard carryout carryout G2+. My question is; can I use original coax that runs to the single LNA block, which is 2.25 gigs, or do I need to run a higher rated coax to the new antenna. I ask this question because I have just replaced OTA coax to the TV antenna 2 weeks ago, and had a devil of a time trying to get the old cable out and finely ran a new cable in a different route, as the old cable could not be removed. Having surveyed the installed sat coax, it will be near impossible to run a new line in without really messing things up, that will require a lot of repair

Follow up: I have completed the install and it is working great. For others that may do this conversion from the single LNB to the winegard G2, I removed the crank-up dish from the roof, and left the leveling ring in place. Installed the G2 on the leveling ring after removing the 4 rubber feet, and put 4 screws down through the ring into the roof, in the front, and 1 screw on each side on the rear side of the dish, sealing all screws and around the leveling ring, and sealing the plate I installed over the 1-1/4" hole on the roof. There did not seem to be a splice in the celling I could find, and the coax on the roof was in really good condition considering it has been on the roof in the elements for over 12 years.

I have just checked on the Belden web site, and the coax is RG6. Thanks to everyone who replied. The last thing I wanted was to find out after the install that the original coax would cause reception problems. Thanks to all again.

Also note that it is NOT outdoor rated

Thanks, but it is not RG59, but has a Belden numbers on it with the gig rating.

If it is Belden 8281, that is their designation for RG59 if my memory serves from my days at Amp Incorporated (left in 1991 so if incorrect go easy on me!).

OK, I'll go easy..

8281 is broadcast standard analog low band video cable. It's also RG-6 size but does POORLY at 1GHz. BTW- Your AMP BNC's were great, but at $5/ea. I hope you're driving a Prevost 🙂 I've personally crimped 10's of thousands of them

It is Beldenn-T 100145 2.25 gigahertzes. I hope there is NOT a joint at the roof as this is what went bad on the OTA antenna run. I believe that the coax is not RG59 because of the size of the center wire. I have run some RG59 and RG6 and depending on the OD of the coax, can be a problem getting a good crimp on the end connectors. The high performance Monster Cable has a silicone other shell that does not lend itself to retaining a connector.

A lot depends on the run. First. Your existing coax likely has a 'Break" in the roof. This is so the exposed cable between roof and antenna can be replaced without replacing the entire cable (A very good design)

You can use the cable from the switch box to the roof, but you need to disconnect from the switch box.

RG-59 is normally what you have and that is not really speced for Sat use but the run is short enough you should be able to get away with it. Just figure however many feet of RG-59 you have, Multiply by 5 to get the effective length of RG-6. In mny case the RG-59 Run is less than 10 feet

NOTE: if your RV is "Sat Preped" odds are somewhere near the center of the roof is a buried length of Coax and a pair of 12 volt wires as well.. There may have been a sticker at one time, or a "Vent" (in my case) the wires are under same. Use a cable tracker to find them if you have them. (Will be cables in teh Electronics bay labeld "SAT".

he has a working sat already hes just installing a newer one if the sat worked with the old cable it most certainly will work with the new one

what numbers are they? Belden in house numbers are easily avaliable.
