Recommended antenna cables
The table below shows recommended cable types and maximum cable lengths
for both TracPhone FB500 and TracPhone FB250.
Check in the data sheet from the cable supplier that both the RF- attenuation
and the DC-resistance are kept within the maximum specified values:
•
Antenna cable RF-attenuation at 1660 MHz: max. 20 dB incl. connector.
•
Antenna cable modem-attenuation at 54 MHz: max. 4 dB.
Antenna cable modem-attenuation at 36 MHz: max. 3 dB.
•
Antenna cable loop DC-resistance max: 1
.
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 instructions from
the cable supplier.
