i was looking for longer cable today and found this at mono RG6 F Type Quad Shielded Coaxial 18AWG CL2 Rated 75Ohm Cable - 12ft - WHITE which is funny because all the white is on back order while pleanty of black in stock. I thinking does the color make any difference in how the cable will hold up in doors or out doors?

Yes. White cable shouldn't be used outdoors because ultraviolet light destroys it too quickly.

really, i was told white reflects light away while black absorbs it. Right now i have 2 six foot coaxial cable strung together which also make me wonder do you loss any single doing it this way, how many lengths can you string together before you begin to loss single. Is one long cable better than short ones connected together even with the right connector

As was written, white falls apart outdoors because of the UV rays.

Yeah, there is a little bit of signal loss at each connection. The more important factor, though, is every connection creates a weak point in the system. Just another point of potential failure. Ingress is the biggest problem.

In some areas, certain animals such as squirells prefer one color over the other to munch on. UV does not matter at that point if they are shredded before the UV has an effect.

aren't these cables UV stabilized for outdoor use no matter what the color. Glad i asked this question then, so white is only good for inside use then. I like the white because it's harder to see but i guess not after the dirt grinds into it. Mono now has HDMI cables in colors, pretty nice.

Some manufacturers do that, but not many. I've seen too many white cables brittle as a bone to even consider using white outdoors.

It appears there might be a market in GREEN RG6

Those Darn Cable-Eatin' Squirrels!
September 19, 2008

Public enemy No. 1 for cable's field technicians? Squirrels, if the chatter this past week on a mailing list of the Society of Cable Telecommunications Engineers is any indication.

“I am getting fed up with squirrel chews killing our cable drops,” wrote one cable engineer. “I know that this has been a long-standing issue, and I am curious if anyone has come up with a quick and cost effective way to reduce pole-to-house-drop cable squirrel damage.”

His plea produced various tactics for shooing away the furry varmints.

“I once smeared a pink, axel-grease-like substance touted to be squirrel deterrent over spans of coax that passed through or near trees making them a convenient and favorite snack for the little buggers,” wrote an employee of one large MSO.

“Turned out to be more like putting ketchup on a hamburger than a deterrent; seems they loved the stuff.”

One SCTE contributor said his cable system has been trying green-colored split tubing to protect the drop around the pole.

“We do not put the tubing on the entire span or drop, just areas that the squirrels seem to set and chew,” he wrote, adding that while it appears to work there’s “no real scientific evidence” to explain why.

That extruded-plastic tubing -- called Squirrel-Guard -- comes from Multilink, an Elyria, Ohio-based supplier of cable network components and other telecom products.

“I can’t explain to you why it works,” said Multilink vice president of sales Matt Ternes. “But for some reason squirrels don’t chew on green things.” While it’s not exactly a cash cow (rodent?) for the company, Ternes said, “We sell an awful lot of this… so I assume it’s a pretty widespread problem.”

Meanwhile, cablers should be cautious about using poisonous substances, warned another technician on the SCTE list, citing a lawsuit against a cable company in the South after dogs in the area died from eating poisoned squirrel corpses.

The problem ain’t going away. By one estimate, there are more than 1 billion squirrels in the U.S., an extrapolation based on data from the Conservation Commission of Missouri – which also notes that the state’s 80,000 squirrel hunters bag around 2 million of the suckers per year.

I boldly predict that cable-sponsored squirrel shoots are in the offing.

On the whole squirrel subject...

I recently completed laying the cable for my up-the-hill installation. 230ft of trench up a steep hill. Talk about digging...

There were a few spots with giant tree roots and one stretch was too rocky to dig through. I picked up 25ft of 3/4" electrical conduit at Menards for $10. I taped the ends and made sure they were down in the ground (I was inspired after watching deer licking the elements of an antenna sitting on the ground. Didn't want to see that happen with the downlead). I also ran the conduit a few feet up the side of the tripod and on the other end (to the underside of the deck).

I used 3/4" because I'm running RG-6, RG-11 and rotor wire.

The stuff is pretty easy to cut and reasonably flexible, too.
