rg6 and compression fittings

[rbnjr 0]

not sure if this is the right category but if i can attach a image to this post i could show what tools im using to terminate the connections with and could get recommendations. basically the compression fitting does not hold the wires after the crinp is done.... not sure whats wrong.

 

thank you.

Are you crimping theRG6 connector to RG58/59 cable by any chance?

the coax is actually labeled rg6...wish it was that simple too. i ordered the wire Bulk Outdoor RG6 + Power Siamese Cable, 1000 ft Spool.

 

any other ideas?

If it's for CCTV then start by using the correct cable which is RG59

RG6 and RG59 both have 75 ohm impedance and so can be used interchangeably. The RG6 also has better shielding and lower loss. The only disadvantage is that it's slightly thicker/more expensive. If those aren't concerns, the RG6 is the way to go.

Do some homework. RG6 shielding is designed for RF inband frequencies. The shielding is NOT particularly effective below 50Mhz which is where the baseband frequencies of CCTV cameras operate. RG6 main claim to fame for CCTV is it's lower DC resistance enabling longer runs if noise immunity is of no consequence. With all the people on this forum seeking help to deal with poor quality images you would think that maybe they might start listening to some proper advice & not people who use youtube as their main source of knowledge ( not referring to you Stan)

Do your own homework. There are CCTV-rated RG6 cables. West Penn 806 is one example: http://www.westpenn-wpw.com/pdfs/coaxial_spec_pdfs/CCTV/806.pdf

 

PART NUMBER: 806

DESCRIPTION: RG6/U – 1 Conductor 18 AWG Solid, 95% Bare copper braid and an overall PVC Jacket.

NEC RATING: CMR

APPROVALS: (UL) C(UL) Listed or c(ETL)us Listed

APPLICATION: Indoor for: Security Cable - CCTV

Construction Parameters:

Conductor 18 AWG Bare Copper

Stranding Solid

Insulation Material Gas Injected Polyethylene

Insulation Thickness .180” Nom.

Number of Conductors 1 Center Conductor

Shield 95% Bare Copper Braid + Tape Barrier

West Penn also makes outdoor-rated CCTV RG6 (4806), direct burial CCTV RG6 (AQC806) and plenum-rated CCTV RG6 (25806). There are other manufacturer examples but I'm most familiar with West Penn.

Thanks for backing me up survtech. The original poster never mentioned how long the cable runs needed to be, and I figure for future proofing in applications such as HD-SDI it couldn't hurt due to the much higher frequencies. Mr. the toss is entitled to his opinion, but there is no need to be such an AHole about it.

My pleasure. I've worked with RG6 on and off (mostly off recently) for years. Until I started using UTP with baluns and active receivers, I used it for runs longer than around 900-1000 feet. Long ago, I even installed RG11 in one or two jobs that had cable runs longer than 1,500 feet. Awful stuff to work with!

 

But in some ways he's right. I've seen many an installation that used CATV RG6 because the installer didn't know any better. Of course, years ago I used to see CATV RG59 used for CCTV in some places (for the same reason). Now it's rare because CATV and MATV have pretty much all switched to RG6.

If suggesting doing some research is being an Ahole then you won't get an appology from me. So when you talked about RG6 were you talking about a cctv rated one? 90% of those who talk RG6 are referring to CATV or digital RF RG6 because they don't really know any better. They focus on "quad shield" and long runs and decide this is just what they need to avoid all the problems. Next thing you know they are on this forum complaining about the quality of their video. All I'm saying is be aware of what you are doing - the information is easily accessable if you need to check on the internet experts.

 

@survtech - I know you are a big fan of twisted pair & baluns for long runs (I'm yet to be convinced) I see the main advantage as easy cabling for co-located cameras on fairly short runs , but would be careful of using it to overcome a run length problems as there are other factors to consider like HF rolloff due to capacitive reactance. For longgg runs the first step should be the normal cable transmission principle of pre-emphasis & de-emphasis (cable equalisation). This has been used since video was invented and is tried & true.

the toss,

 

We performed a series of tests comparing baluns at 1,000 feet and 1,500 feet. Passive-passive works very well at 800-1,000 feet of CAT5e, depending on the baluns. At the limits, there is a bit of loss in the color burst, causing colored "fringing" around the white characters from our Pelco 9760-MDA's but no loss of resolution. At 1,500 feet, the color burst was basically gone, as was the color itself, and there was noticeable degradation in the "Y" (B/W) signal's resolution.

 

Adding active receivers brought the picture quality back to excellent. 1,800 feet is about the maximum length we've tested using passive-active (active receiver). We haven't tested active-active as we have no runs that are more than 1,800 feet and passive-active gives excellent quality.

 

We've also compared two identical cameras mounted next to each other at distances of about 750 feet to our Control Room - one on West Penn 25815 RG59/U Plenum coax and the other on CAT5e with approximately 700 feet on a 25-pair trunk punched down to 4-pair at each end and terminated with baluns at each end. Although our Camera Master shows slight differences in signal levels, I defy anyone to tell by eye.

You dont have termination closets close by (IDF?) so that all cameras don't have to terminate back at the main encoders (MDF closets?)? Why not setup closets so that no run is more then 100-250 feet for ease of running wire, cost savings, etc. Is this an old property without network closets?

Haha! Our IDF closets are overflowing with IT's equipment. Besides, why bother? While maintaining 100 meter limits is necessary for IP, it is not needed for analog. And, don't ask management to take space away from the gaming floor for additional IDF closets. At least if you want to keep your job

 

We have managed to retrieve a bit of space in some IDFs for networking for our IP HD cameras but there's no way we could accomodate all 1,200 inputs. Our 25-pair backbones run from our Server Room to "66" punchdowns co-located with camera power supplies and RS422 code distribution units (for PTZ control) that are mounted to our cable trays at strategic locations.

You are management no?

 

"Sorry I cant get that side shot of the blackjack table for you"... "I can only do short runs"...

"How about I setup a IP camera and plug it into our IDF closet?"

Just put the encoders in the Drop ceiling... Just write down which ceiling tile its hidden above...

OK you are impressing me , I might have to get more adventurous with UTP installations. I have never used active baluns so their performance is an unknown to me. Do they have cable equalisation capabilities or just signal amplification?

[survtech 0]

Good active receivers and transmitters have equalization. Some receivers auto-adjust the gain and equalization while others require manual adjustment of gain.

Surveillance management often has little input on casino operations. IDF closet space would have to be added, at a substantial cost and disruption to operations. Not going to happen.

 

We are in the process of installing network equipment in some IDF's but once we max out the switches, there is no room for more. In that case, and for certain other areas, we'll just have to bite the bullet and use EoC or EoUTP devices.
