a couple of suggestions:
- Use a captive center pin on the N male connector.
for example, Kings Electronics Inc. N male, model # KN-59-176 for RG-214
coaxial cable,
center pin is solder type and captive, will not move axially. Wrench
clamp on the shield.
Kings cage = 91836
mil spec: M39012/01-0005
a few bucks each
- consider adding a foam in place insulation, inside the plastic pipe
to support the coaxial cable.
drill a 1/8" hole every few feet and squirt in the aerosol foam till it
comes out of the hole.
Go for the minimally expanding insulating foam you will find in Home
Depot or Lowes.

Thanks, but I don't picture what you are trying to describe.
Are you talking about tees and elbows in the pipe or cable?

Gaffa tape the cable to the supporting pipe with a small drip loop
into the connector.

Why not juts use Ty-raps as we do in the commercial world (black ones for
outdoor use)?

No. The glue of Gaffa tape ages. Also, it is not very nice to the cable.
Gaffa should not be used for permanent installations. For temporary
installations I prefer using a strap (no the narrow plastic straps, but
the wither weave-type, not sure what they are called in english) running
at least one turn around the cable. Dropping cable that way helps. For
longer runs the cable should be strapped to some fixed structure or a
steel wire and done in such a way that the cable is not fully stretched,
so that each strap-point actually takes the force of the cable downto
the next strap-point. This way the cable does not get to carry heavy
loads, which it is not designed for, the dielectrum does not get a firm
grip around the center wire...
In general Gaffa should be used conservative and only for short periods
of time as removing the glue becomes an issue and even more annoying as
it has dried out and hardend to the surface but lost the grip to the
actual tape... which makes the grip brittle.
Cheers,
Magnus

Buy decent gaffa tape, not the duct tape variant :)
Sorry, I agree with you really Magnus. I was more indicating that the
cable does need to be supported by being attached to the mast
structure than have all that weight on the poor connector. Gaffa is
great for temporary work where is is tough and sticks well, and is
easy to tear-down an installation.
Using black wide cable ties for the antenna cable would be an idea and
be easy to take down too.

Even with really good stuff, it is not the long term solution you would
like.

Indeed. Temporary < 1 week

In my experience high quality electrical tape (ie. 3m Scotch brand tape) will also work okay for securing cables to masts if you cut the tape to length as opposed to stretching it to break it.
High quality UV resistant cable ties are probably a better choice though but be carefull not to over tighten the cable ties.

I've used both Velcro scraps, plastic cable ties and electrical tape
for strain relief on my wireless connection. Velcro straps seem to
work the best, but need to be replaced every 8-10 years or so. The
rest is crap. Since I was reconfiguring the setup every few years, I
could easily replace the worn/weathered straps when I did the
reconfiguration.
I don't know what I'd use for a more permanent installation.
