RG-11

Can you run RG-11 inside the house until the Tuner or is that too much of a Pita?


And compression connectors are they really better the regular crimp connectors?


I love the numbers on CATV Hardline; 0.5 db loss over 100 feet. I'm sure the connectors are expensive and hard to get. I would love to run that from the CM7777 to the grounding block.

Stampeder,


What about RG-6UQ Quad-Shield?

Is it really better then Rg-6?

And the difference between 60 % braid and 90 % braid?


Thanks,


Intravino

To me quad-shield is also overkill unless you are stringing your coax through/past areas of high EMF interference, which is very rare in a typical home.

Having said that, other members have pointed out that some stores sell it as their basic RG-6 type so if the price is good I don't see any harm in it. If you are going to crimp it yourself you'll have to be careful with how you handle that extra shielding so that you don't void it or cause a short.

Some RG-6 comes with a "messenger wire" that is stiff wire bonded to the outside of the coax. This type is not as flexible as standard RG-6 but some people use it to have a chassis ground on all their linked OTA gear, including the ATSC tuners/TV sets. It is not suitable for lightning protection or proper grounding, it just establishes a steady 0V to drain off any static electricity buildup.

Correct me if I am wrong, but isn't that "messenger wire" actually for telephone pole mounting to take the strain off of the conductors when stretched from pole to pole?

Yup, that's the original/real purpose of it: for supporting otherwise unsupported horizontal spans hanging between posts.

Here, I use RG6Q on the primary antenna run from the top of the tower, where there's no margin (well, okay, 0.1dB of margin) to spare. Every little bit helps, or so I like to believe).

In addition to above: "Messenger" coax is indeed used for aerial installations. It is not necessary to create multiple ground points for cable.

The coax with the "gooey" dialectric is burial cable. The substance assists in keeping the cable water tight should it be slightly damaged.

RG-6 Cable & F Connector Questions

I ran into a problem with RG-6 cable and F connectors.

I always thought there was just one size of F connector and went to our local electronic parts emporium – very reasonably priced place with surplus parts such as motors, power supplies, transformers, component parts etc. I found a nice 100’ length of RG-6 cable made by Phillips Cable (good name) that was flexible and had something called a quad braid. I selected this and asked for the F connectors to go with it. I wanted the type the CATV installers put on with the knurled end that is easy on your fingers. He showed me several types and I selected the one where the screw-on end gets pushed back on the cable with a special tool that I would need to buy for $15. The sales clerk even showed me how to put one of the connectors on the cable and, this is when the problem occurred – it went on briefly but didn’t hold. He said the quad cable takes a special connector which they didn’t happen to have in stock because there isn't a great demand. I didn’t buy the cable because my intention was to customize shorter lengths from it and I was afraid that the connectors would be difficult to find.

a)Did anyone else run into this problem with F connectors and quad cable?
b)Any suggestions on what to look for in good quality RG-6, F connectors and cable connector tools?
c)Does RG-6Q always imply quad cable?

On looking around various home renovation stores I was quite surprised at the variety of F connectors and tools used to install them on cable.

Any other way to distinguish quad connectors from regular RG-6 connectors?
It depends on the brand of compression fitting, some have blue bands for RG-6, and black bands for RG-6Q and some have no bands at all, heh.
Basically you have to look on the package you buy.

He showed me several types and I selected the one where the screw-on end gets pushed back on the cable with a special tool that I would need to buy for $15.
I didnt like the one for $19 and $59 was to much to spend for my limited use, so I made my own, heh.



Only took about 45 minutes to make it from stuff I had lying around. It works quite well.

You do need a correct size tap to make one. That brass bolt is a common toilet bolt with a short piece of copper tubing on the end. That allows it to compress the inside without damaging the center coax wire. The tricky part is drilling and cutting and filing the end where the coax goes in. It has to be large enough to let the coax fit, but narrow enough so the compression fitting doesnt go thru and has a place to rest against the bar for compressing it.

That explains it. The store I went to kept them loose, in the drawer of a large parts cabinet and, I don't think the sales clerk really knew the difference between the connectors. I do recall seeing red and black connectors but I didn't know the significance of the colours.

I like that homemade affair. It does the job very nicely. I probably have all the bits and pieces to come up with something very similar since I rarely throw anything away.

Thanks for sending the photo and build instructions.

Hmm. Radio Shack ? Or if nothing else, the Radio Shack syndrome. Like I said about the colors, that seems to depend on the manufacturer as far as I can tell. Just like the color coding on the backs of motherboards, there are NO color coding police. (but watch out for dem mattress tag police, heh)

Yeah, she aint purdy or professional, but she does the job, heh.

Youre welcome.

I was shopping for that last weekend.

Home Depot have the connectors for Quad Shield and they have the tool (Ideal Brand) but the tool at Addison is the same price $ 30 but you can do also RCA connectors with it. The one at HD just does F -Connectors.

Rona has the same tool like Addison but at $ 47.00. The tool is behind the counter at Addison.

Where did you see Quad shield Rg-6 cable?

My Home Depot has it on a roll for 34 cents a foot I believe. I got 260 ft (est) of good quality RG-6 Quad Shield (the specs are the same as typical RG-6, which is better than most Quad Shield) at my local flea market auction recently for $7. It may have gone for the minimum bid of $2 typically, but there was another antenna nut there, heh. Fortunately for me, he didnt know quite how good it was, and didnt bid $8, heh.

If it is only for short runs I would only use regular rg6 as the quad is better for long runs because the shielding offers less loss over long distances.
Not true,

"Tri-shield" offers lower loss than quad-shield. The purpose of quad-shield is to prevent "re-radiation" found mainly in "Cable TV" applications. It is not necessary in OTA applications, and actually results in "more" signal loss. Save your money and go with the tri-shield.;)

...going to try one myself! Never thought about building one. I'm good at following other people's plans...lol.
Not really much of a plan there, heh. You just need a sturdy u shaped piece of metal about 4 inches apart, a correct size tap and an old toilet bolt. Warning, DO NOT USE the present one holding down your toilet. Disaster will follow ! Heh.
