IF Cables
The AU-RE Radio Unit is connected to the indoor unit via an IF cable
carrying both signals and power. The IF frequency is 440 MHz. The
maximum permitted attenuation of the IF cable is 15dB at 440 MHz and
the maximum permitted DC resistance (the sum of the DC resistance of
the inner and outer conductors) is 1.5 ohms. This enables a cable
length of up to 30m when using the standard RG 58 cable.
If longer cables are required, a cable with lower attenuation and/or DC
resistance should be used.
Table 2-2 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).
Cable Type RG 58
Maximum Cable 30
Length (m)
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.
