Remarks Filoradio
- All electricals values are given at 20°C
-
Coupling loss and longitudinal loss are mesured by the free space method according to IEC 61196-4 cable high = 2m / cable-antenna distance = 2m / dipole-antenna λ / 2
- The coupling loss measurements are performed with the antenna oriented in a direction radial or parallel to the cable
- As with any radating cable, the performance in tunnel or building environments may deviate from figures ed on free space method.
- Coupling loss values are given with a tolerance of +/- 5dB
- Longitudinal loss values are given with a tolerance of +/- 5%
Stop band Filoradio RL-L
CAUTION:
The cable cannot be used at stop band frequency of 60+/-5 MHz
