RG-6,RG-6 quad shield,RG-59 whats the difference?

Just a note. There is RG59 50 ohm, usually used for antenna cabling for audio devices and RG59 75 ohm that is used for CCTV or CATV applications. The RG59 for CCTV app. is 95% braided copper shield usually with a solid copper conductor. The RG59 for CATV usually has an aluminum shielding with a stranded or solid center conductor. It is also 75 ohm. It's kind of confusing and usually doesn't matter too much on short runs, but on longer runs, the wrong cable will cause problems.

I wouldn't let a minimum wage kid that just graduated high school that found a cool job for the catv company because he gets free cable and internet in my house... :grin: Sorry Hal, but times are changing, catv companies hire kids and politically correct call them techs....

my parents hired one from a comcast subcontractor to put cable in the upstairs bedroom. one bedroom on each side had cable (4 bedrooms) he drilled through the wall of each bedroom and put a splitter and a piece of rg 6. i was pretty angry that he done that. theres a nice big chase right on the side of the chimney he could of went down. might of taken longer but its a muich more professional job instead of drilling through walls. comcast is notorious for doing that kind of hack work.

There is NO 50 ohm RG-59. By definition RG-59 is 75 ohm as is RG-6 and RG-11. You are probably thinking of RG-58 or you saw a typo.

Unhappy cable customer

Unhappy cable customer

Has anyone experienced this. I got this call from a new customer that his phones and cable in his house has not working properly. It had been this way for three or four months.
When I arrived, sure enough it was all jacked up. Phone lines were crossed and the cable connectors were installed terribly. There are nine TVs in the house. I changed all the splitters also. After all was said and done I sent him the bill. About four weeks later I decided to call him. Now he tells me that the TV in his bedroom doesn't get channel 4. I asked him to swap that TV with another that he knew received channel 4. After another three weeks of calling him he said he finally did and the problem is still the same. Is this possible? Is there something I may have done to cause this.

if they drill a hole from inside to outside and through your gas meter theyre called comcast

I thoguht it was Charter.

...

If the foil isn't glued to the dielectric, you fold the whole affair back and then push the connector barrel in between the dielectric and the foil.

...

FWIW, the manufacturers (Arris-Digicon, T&B-SnS for certain) disagree with you...

...the foil goes in the barrel with the dielectric.

...and I agree with the manufacturers :wink:

There is no reason that RG-6 cannot be split. It's just a coaxial cable like any other. There will be about a 3-4 dB signal loss for splitting it.

I believe this myth comes from the direct subscriber satellite TV market. The small dish satellite systems used more bandwidth than their cable predecessors so the installs went from RG-59 to RG-6 to make this work. At the same time, satellite signals cannot be split because of the following.

The satellite signals are downlinked on two different channels at the same frequencies. This is done with polarization diversity. One channel is RHCP and the other is LHCP. The DTV receiver selects the polarization by placing one-of-two distinct DC voltages on the coaxial cable. This voltage is used by the LNA to power the amplifier, but it also senses the voltage level and selects the correct polarization. If you try to split the signal to multiple receivers, the selection process gets confused and you only get the even or odd channels, but not both. This description applies to the old single satellite systems. The newer multiple satellite systems are similar, but more complex.

You can still split a DTV signal, but you must use a multi-switch.

The transmision speeds are much faster and bi-directional the High speed modem must be placed in the first split to have enough signal to work properly. I have NEVER had a callback on a cable install. They are nicely profitable for me but I do not negotiate.99 per run How many do you want ?? I watch all of the local guys around me try to split and have nothing but trouble. I also upsell small ups systems to power the phone line in an outage now.
