Re: Structured wiring questions for new (old) home

Rg59 will not work for satellite tv very long
The stinger is too small gauge to carry the voltage - I have seen many burned out stingers on sat tv installations
RG59 also is far more leaky to some of the frequencies used with digital - it was designed for off air use decades ago
If you ever want sat tv, the installer is gonna wrap your house with 3gig swept RG6, with solid copper stinger (not plated steel stinger)

99+% of cat6 installations don't meet 6 specs, you got to be really good at terminating and use top grade connectors to pass more than 100 megs - weak link in cat6 is often the connectors
Why spend the $$ if you are not going to be pushing greater than 100 meg speed files around?
cat5 is way more than adequate for all but most super heavy duty, huge file transfers between work stations

This is mostly untrue. The gauge of the center conductor is going to depend on the brand and manufacturer of the cable.
The same goes with the braid or shielding. There's crap RG59, and there's good RG59 - Just like there's crap RG6 and good RG6. You can't just put a blanket statement out that all RG59 is bad.
That's like looking at a Kia and then assuming all cars are crap based on that Kia.

My 30 year old RG-59 has a braid and foil shield, which I suppose is a good sign. But there are no markings that I can find on the jacket.

Interesting logic but mostly incorrect.

Burned out stringers because of voltage? 13 volts at very low amperage for the LNB's is not likely to burn out much of anything.

3 GHz? RG-6 solid copper. Ok what source is this 3 GHz coming from?

You are entitled to your opinion Jack

I have been working in the field for well over a decade and am speaking from real world experience

I am sure there are plenty of exceptions to any 'rule' but doesn't change the facts that certain materials are not engineered to perform certain tasks - even if they sometimes can/do

fwiw - sat tv receivers use 13 and 18 volts
100% of sat installations REQUIRE 3gig swept/solid copper coax - no exceptions allowed

Around a decade? Ok

I guess I'll have to stop watching my Directv as it can't be working without 3 GHz swept/solid copper coax and 3 GHz barrel connectors.

How about posting the info from Directv and Dish stating that. I agree that RG-6 is a requirement but 3 GHz

It's important that you use RG6 cable due to the frequency of the digital signals it must carry. RG6 has the correct impedance (75 ohms) and acceptable signal losses at 950 to 1450 MHz.

950 to 1450 MHz is a long way from 3 GHz.

It never ceases to amaze me the statements I see on this thread.

A statement I and my co-workers can prove wrong everyday when i come into work and visit the random house of the day in town to tear down their satellite service and put in cable. The only 100% requirement i seem to find is that the contractor use as much existing wiring as possible, weather the stuff be good or not. I swear if the satellite contractors in this region could crimp and f fitting on twin lead, they'd use it.

Around here we usually refuse to re-use sat wiring, as when they do run new stuff, it is the cheapest stuff we have ever seen. The stinger doesn't seem to hold up for any amount of time in the cable once it is put in a compression fitting. The core also seems to have little to no rigidity, and it will easily bend over itself, basically ruining the cable at that spot.

May I be so bold as to suggest that one can try to make a point without being an assh*le in the process?

I think you may find a bit of helpful info at this link - be sure to read the complete thread as some later comments will help in understanding what we are REQUIRED to do.

Yes there are sub contractors who don't give a 'bleep' and cut corners and don't follow the rules
Less than optimal service is often the result...

Unfortunately you are too often correct
There are legions of poorly paid subs who cut every corner they can to maximize their meager pay
Cheapo cable is a frequent corner to cut
100% of installations are infact REQUIRED to use premium cable - not the same thing as every installer DOES use it

These days, when returns to stockholders are vastly more important than maximizing customer satisfaction, quality control budgets are among the first to be cut

The 'easy to bend' stinger is actually a potential indicator of superior cable
It implies solid copper rather than plated steel - quite a bit more expensive than plated stinger
