our company installs alot of modulated cable systems over coax. We run into issues with the size of pre-made coax jumpers being too bulky, requiring us to use spacers on the TVs and 90* adapters to keep everything as tight to the wall as possible. Making them isnt a feasible option, what is the best coax jumper for minimal bulk(3' variety)

RG6 being what it is, I dont see how you remove bulk from it. I can't imagine how making cables is not within the realm. I would build my own using dual shield RG6 and a Belden FSNS6URA right angle compression F connnector to eliminate an adapter on the TV end. If your volume requirements are large, a contract manufacturer could build them for you.

We are doing it in large bulk. Most of the time its 50-100 TVs being modulated. Id rather pay someone to have the cables pre made as opposed to having my guys have to make them on site. Do you have a manufacturer in mind?

Monoprice? or several available on Amazon?
Do you need more specific ends or something?
1.5, 3, 6, etc

They’re just too bulky from either site. Makes keeping tv tight to the wall not possible. Even with 90* on both ends.

As I said in an earlier post about my toggler buying methods, a person who's doing this work professionally should look into professional methods of doing the work. That applies to everything in your source chain.

If you're making cables yourself, you're not buying connectors by the dozen, right? You're buying by the thousand. Is there a pro cable stripper that makes stripping a much faster and uniform thing than hand work? You should have one. Et cetera.


size... is that cable diameter? Radius of cable bend? Length of connector, which requires depth? Improperly close spacing of jacks on any custom-made jack fields you're using? Improvements you could make if you custom design jack fields?


You don't state what cable type you're using (RG-6, RG59, etc). And if it amazes you that I even dare to mention RG-59, look up the data on it and RG-6 and figure out the difference in signal attenuation and any other performance problems. The differences will probably be in the range of maybe a tenth of a dB across the board... for a three foot cable. And that's what you're talking about. If you were talking about twenty feet of cable, then things are not so equal.

Investigate the ready-made cables that are used in DirecTV systems in high-rise buildings. I've only done a few of these, but the cables from the parts vendor (that someone else ordered, so I don't know the vendor name) were on the order of 3/16" in diameter, and VERY flexible.

Also, call Pasternack (www.pasternack.com). I'd recommend going to their website, but I just did, and they offer over seven thousand different cable assemblies. Talking to a person at the company would be MUCH better than trying to choose a cable from their list.

I have received mailers from Pasternack over the years. I have never bought from them because I did not need the incredible excellence of the products they make, nor did I have the budget to even start to entertain the idea of buying from them. But you said "best," and that's where I'd go to get "best."


By making a better wire choice, like I said above.

Buying from a factory that pumps out cables for a living would absolutely cost you less than setting up your own assembly line, especially if your line only worked a few hours per week.

Every five or so years when I need this name, I've always forgotten it, but... a Belden engineer literally wrote the book on low voltage wiring, including not only theory but also how to run a low voltage wiring company. He and I were discussing cable shielding about twenty years ago, and when I proposed that there's really no need for quad shielding unless you're running cables, say, in a room directly underneath a TV transmitting tower, he said, yeah, that's pretty much right.


Pasternack is essentially that.

Honestly, coax is just about the easiest and mindless task a tech could do. The amount of time dicking around with trying to get the TV flush your techs could terminate 10 jumpers.

Use a 90 on the TV then use a recessed keystone Jack for the coax.

Or use a grommet, then keep the wire long, put end on and wire directly to the TV.


Seems like you are making this way to complicated. With a sharp cutter and stripper, good quality compression connectors with RG6 it’s dumb easy.

You or a contract manufacturer might use use a machine such as this.

Or try this.

I don't know what type of bandwidth you need. I've had some issues with generic 90° F-F elbows.

6ft. Seriously flexible. I use one for testing purposes. I’m sure you can find shorter. Or make them.

Planet Waves works well for this application. RG-59 crippled satellite distribution and cable guys have always looked down their noses at it. However, all head end cable at provider locations is RG-59 (albeit with high grade metal construction).

Should also add that you can make them about as fast as it would take to un-bag a pre-made cable, remove the bread ties, and deal with the cable memory...

The Planet waves are looked down on from the cable industry because of ingress and egress from poor shielding at the connector. My assumption because of screw design. Not a 360 degree compression. Same as twist on and poor electricians using pliers and leaving a 1/2 in of braid hanging out. Ingress follows the cable and enters the drop system wherever the shielding is poor. Causing HSD issues and video issues if severe enough. Egress is another story. System must be closed to use the frequencies cable systems use. Simple because leakage causes interference with other users of same frequencies. And the FCC does fly overs detecting and mapping these leaks as does the cable companies. Ever had a customer trapped for noise? Really want to screw up HSD for a node, back feed Directv/AT&T onto the house coax and drop system still connected to a tap.

Recessed box, plus 90 degree adapter? Or, as stated, premade at a price.

What does that mean? It's a simple fact that satellite signals use such high frequencies that the loss characteristics of RG-59 make the wire unsuitable for satellite distribution. Hell, I dropped RG-59 for plain old TV antenna systems in 1985, once we started to pay attention to UHF channels.


You're saying "all" so I'll assume you're okay with generalization.
Cable companies do not want installers who think. They want installers who will always do a perfect installation. For instance, I knew a cable installer who would never install an F-81. That's a good idea, but his reason was that they always attenuate a signal so much that the signal is ruined. He was taught a lie, but that lie guaranteed that he'd never do a bad installation.


That's totally appropriate because RG-59 can pass signals of the required frequencies. See, we can't use RG-59 for satellite... for more than a few feet. And nobody wants to limit satellite signal distribution to a few feet.
