For example, with a Yagi antenna system, 10 m of cable, a surge protector, and a bandpass
filter, you would calculate the following antenna system gain:
Antenna gain:
12.4 dBi
Insertion loss:
- cable:
4 dB
- surge protector:
0.2 dB
- filter:
1.1 dB
The total insertion loss is 5.3 dB, which gives an antenna system gain of 12.4 dBi minus 5.3
dB, or 7.1 dBi. Since the system gain is lower than the maximum antenna system gain of 9.1
dBi, this antenna configuration is valid.
