LMR-400 coaxial cable has a minimum bend radius of 2 inches, as shown
in Figure 4-8; don't bend it tighter than that or you'll crimp and damage
it. When negotiating a corner with this cable, be certain that the arc of
the bend falls within 2 inches. LMR-100 cable is much more flexible, with
a minimum bend radius of .25 inch.

Remember that you always want to use the shortest possible length of
cable that's practical. That doesn't mean you have to cut diagonal paths
from one place to another, but if you can easily and neatly use an angle
between the antenna and termination point, go for it.
3. I mark where to place the cable clamps by putting a piece of masking
tape where the clamp will go, and placing my marks on the tape (not
on the metal or upholstery).
By using any existing screw holes -- say, those for the mounting screws
for panels, shelves, or cabinets -- you can secure plastic cable clamps
without making any other holes. Even if you have to replace the existing
screw with a slightly longer one, it makes for a neater job.
4. After you determine the path, take down your cord and measure it to
find out how much cable you need for your antenna. Make sure you
leave marks where the clamps will go.
5. I find it easiest to install the cable clamps, one at a time, as I'm run-
ning the cable. You can also slide 'em down the cable so they're
stacked and ready to use.
Making the connection
Once you've figured out where you're going to mount your antenna and the
path the coaxial cable will take from the antenna to the termination point, it's
