General
Double screen 50
Ω
coaxial cable must be used for connection be-
tween the TPU and the various Antenna Units.
The coax cable should be secured by laying the cable in a tube and/
or by fastening the cable to avoid damage.
A "pigtail" is normally required for connection to the TPU.
The maximum length of the coax cable is limited by the DC and RF
loss through the cable:
Maximum DC loss: R loop 0.6 ohm
Maximum RF attenuation at 1525-1660 MHz: < 10 dB
The table below lists suitable double screened coax cables:
