Last night was trying to screw a cable (connector) onto
the tv. Couldn't do it -- hands too big, crowded space.
(Wife did it.)
Question: professionals, how do *they* do it?
Special tool? eg something that clamps *around* the
nut, with some kind of belt around it that you pull and
which thus turns the nut?
The push on connectors can cause a lot of signal ingress back into the cable
plant. Not a good thing. Some MSO's will put filters that block out certain
frequencies so it doesn't feed back to them, others don't. Still it is
always a good idea to use the right connectors, as it will help you out in
the long run. That, and use quad shield RG-6. Accept no substitutes. :)
I work for a cable company, and one of our headend guys gave me what he
called a "Church key" that looks like a extended socket, but with a groove
running along the side that allows the actual cable to fit through and you
can tighten the connector. It works great for small spaces. Here's a picture
of what it looks like. That website refers to it as a "security shield
tool" - I can see why the slang term is church key :)
I have push on F connectors on all my TV's, VCR"s and my cable modem. They
do NOT cause a problem if they are properly screwed on to the standard F
connector on the cable.
I had a go around with my cable company when the cable mode itself crapped
out and the "tech" that came out took the push-on connector with him. I
called the cable company and the yo-yo had to make a special trip to return
it. As I told his boss, it wasn't the lousy buck for the connector it was
the fact he had no right to take it.
End of the rant. On with the discussion. It is pretty easy to design a
little connector like that. The electrical requirement, from a transmission
line point of view (after all it is a very small piece of transmission line)
is that the correct ratio of the diameter of the inside conductor and the
outside shield's inner diameter is what establishes the 75 ohm requirement.
That is a handbook lookup. The other consideration is the mechanical
integrity. At one end you need the right thread. At he other end you need a
nice snug fit and a good overlap with the mate on the set. Unless one gets
mauled I have never seen one that is either too loose or too short.
I do not believe that the haranguers who say these connectors are no good
have ever had a course in transmission line theory.
Glad I wasn't the only one who thought so!

It has all of the distinguishing marks LOL

There are special tools:
But normally if you start at the corner and work your way out you'll
have room. It's analogous to "not painting yourself in a corner".

Damn, I have always wondered exactly that; while cursing those cables that
take me 2 hours to screw on.
But, I have been too embarressed to ask. I just figured I was clumsy.
I might buy one of those $8 tools. thanks for asking.
