Installation of the ADU
3-22 Chapter 3: Installation 98-141779-G
If you want to use an alternative ADU cable make sure that the following requirements are
fulfilled:
1. Check the data sheet from the cable supplier to verify the values:
The RF-attenuation and the DC-resistance are below the maximum values specified
below:
• ADU cable RF-attenuation at 1950 MHz: Max. 20 dB including connector.
• ADU cable RF-attenuation at 4450 MHz: Max. 35 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.
2. Respect the specified minimum bending radius, see the documentation from the cable
supplier. If this is not the case, the loss in the cable will increase.
