3.3.4 Alternative ADU cable
The maximum allowed RF-loss in the ADU cable must be 20 dB at
1950 MHz and 0.9 Ohm DC. This is to ensure the performance of the
system. Preferably choose one of the cable types listed in the table
below.
Check the data sheet from the cable supplier that both the RF-
attenuation and the DC-resistance are kept within the maximum
specified values:
• ADU cable RF-attenuation at 1950 MHz: max. 20 dB including
connector.
• ADU cable modem-attenuation at 10 MHz: Max. 2 dB
ADU cable modem-attenuation at 36 and 54 MHz: Max. 4 dB
• ADU cable loop DC-resistance max: 0.9 Ohm.
Also ensure that the specified minimum bending radius is respected. If
this is not the case, the loss in the cable will increase. Check the
documentation from the cable supplier.
