this type of repair would ob-
viously not be a problem. But
if it‘s in a less accessible lo-
cation such as on a roof, then
the picture looks completely
b) Problems with screw-
on „F“ connectors would be
nothing short of fatal for a
professional installer. Not
only because such a repair
would have to be handled
under warranty, but also be-
cause this would damage the
professional image of the in-
Considering all this, you‘d
have to ask yourself why you
would opt for such a low-
quality type of „F“ connector
when there are companies
like PerfectVision that offer
long-lasting, exceptionally
stable and extremely easy
to install „F“ connectors for a
comparatively low price?
We decided to have a
closer look at the „F“ con-
nectors labeled PV6U-EUR,
PV6UE-05, PV6UE-UM and
PV6-PV as well as the corre-
sponding PV100 and VT200
installation tools.
The first question is:
what‘s the best way to strip
the coax cable? If you want
it as easy and as comfortable
as possible, you can use spe-
cial stripping tools (see Fig-
ure 1), but this task is also
quite easy to do even without
these special tools. Using a
sharp knife, carefully cut off
about 15mm (0.6 inches) of
the outer jacket of the cable.
With quad shielded cable the
wire mesh was turned over
and the insulation under-
neath was removed.
If you have triple shielded
cable, this step is eliminated.
The now exposed wire is not
folded back and the insulator
underneath is kept in place.
It should lie as close as pos-
sible to the dielectric (the in-
sulation layer around the in-
ner copper conductor in the
center of the cable).
Now only about 7mm
(about 1/4 inch) of the di-
electric is removed thereby
exposing the inner copper
conductor. The PerfectVi-
sion compression connector
is then placed carefully over
the coax cable until the di-
electric is flush with the „F“
hole. The center copper con-
ductor should be sticking
out about 2-3mm (about 1/8
inch) from the „F“ connec-
tors opening.
Once you‘re sure that the
cable was properly prepared
and is sitting correctly in the
compression tool, a hefty
squeeze of the tool‘s handle
is all that‘s needed to push
the two halves of the „F“
connector together and com-
press the cable in between.
The resulting connection
between the connector and
the cable has excellent elec-
trical conductivity and also
provides the inside of the
connection with perfect pro-
tection from moisture.
And in case you can‘t quite
recognize it in these pictures,
both of these tools come with
a small hole that allows the
inner copper conductor to
poke through without being
damaged while the „F“ con-
nector is being attached.
