7. COAXIAL CABLE
Coaxial cable will be required to attach the TRACER 4206 to the antenna. The length of the cable will vary
from a few feet to several feet, depending upon your application and the proximity of the TRACER 4206
to the antenna.
Various grades of coaxial cable will work sufficiently well for connecting the TRACER 4206 unit to the
antenna. A low-loss coaxial cable is suggested to minimize cable losses. One end of the cable will require
an N-type male connector (plug) to mate with the TRACER 4206 unit. The other end of the coax will
require a connector compatible with the antenna chosen for the installation, which is usually also an N-type
male connector (plug). Additionally, it is recommended that both connectors on the coaxial cable be
weatherproofed from the elements to prevent corrosion and electrical shorting.
Table 3 gives typical loss figures for some of the more common coaxial cable types, per 100 feet.
