Chapter 2 - Installation
Table 2-1 provides detailed information about common cables such as
the RG 58 and RG 213. If the spectral environment is polluted with
noise in the 440 MHz band, it is recommended that a higher quality
double-shielded cable, such as the LMR 200, LMR 240 and LMR 400,
be used. (These cables are manufactured by Times Communications).

If you are using coaxial cables other than those listed above, consult the
cable manufacturers' specification to ensure that the cable's
attenuation at 440 MHz does not exceed 15dB, and its DC loss (center
conductor plus shield) does not exceed 1.5 ohms.
