Extending coax cause signal loss? |
|
|
I'm routing all RG6 cable (4 lines) in my attic to an
Antronix splitter. At least two of the cables are too
short to reach the splitter. It seems I have two options:
* use the existing cable to pull new cable. Or,
* extend the cables using "Feed Thru/In Line Connectors"
Obviously the latter would be easier, but I want the job
done right and will pull new cable it that's the "preferred"
method. Any input would be appreciated. |

New cable is always preferred, but extending your existing cables is also
acceptable.
Usually it's just a question of budget and time (and conveniance).
If done correctly with high quality parts it will have minimum impact on the
signal.
Since it is for yourself and you want it done right, new cabling is the way
to go. :)

Sounds like what you need, is a cable stretcher. ;-) |

Tips on using existing cable to pull new cable? |
|
|
Thanks Crackhead! (oh, and you too James ;)
Now assuming i can't stretch the cable far enough...
Can anyone tell me the best method when using an existing
cable to pull new cable?
One cable is in an exterior wall and the roof is so low it will be
difficult to even get close.
Overapping the two cables and taping them together should work
as long as the existing hole(s) are big enough. But what it they
are not? Tape them end-to-end??

To use the old cable, to pull a new cable. Best to go with a
two step process. Tape some pulling twine to the old cable,
and us the old cable to pull in the pulling twine. Now you can
attach the twine to the new cable and pull that in. It is usually
wise to pull in a second piece of twine when you pull in the
first one, that way if you break it pulling in the second cable,
you are not completely screwed.

Tape the existing coax and the new coax to a few feet
of pull tape such that the two coax segments don't overlap.

No doubt it will break if you use cheap twine. Use some decent rope to
pull the cables with.

I use cheap electricians pulling twine. I buy it by the 5000 foot bucket
at
the electrical supply house. It's cheap stuff, but it has more strength
than
my arms do. For pulling in heavy cable, ( which this coax sure isn't ) I
have some braided nylon tape, which has a breaking strength of somewhere
around a thousand pounds. The second strand is in case you abrade it
on a sharp edge inside the wall you can't see, which will severely weaken
any sort of pulling twine or rope.

Of course option #1 is preferred, but if that is not possible, try #2. If #
2 fails, try boosting the signal with a zero loss booster. It's basically
an amp which maintains a 0db signal throughout the run. Electroline has one
such model - you can find them on eBay.
Also you should consider using an amplifer anyways - since a splitter often
degrades the signal considerably.

Do you mean an Active (zero loss) Splitter, which has an amplifier with
gain equal to the insertion loss of the splitter. The only way for an
amplifier to compensate solely for the loss of passives (splitters,
directional couplers) is to attenuate the output of the amp equal to the
loss through the devices. (You could pad the input instead, depending
on the input levels to the amp.) Manufacturers have no idea what any
given distribution system is like.
CIAO!

Yup, that's what I'm talking about.
