Antenna cable length
The GA150 is supplied with a fitted 10 m (33 ft.) cable. The
length of the antenna cable can be extended if required.
The antenna cable length can be extended by up to 10 m (33 ft.)
giving a total maximum cable length of 20 m (66 ft.)
50 ohm coaxial cable and reliable connectors (offering protection
against water ingress) must be used when extending the antenna
cable.
Note:
Extending the cable length by more than the
recommended maximum length will result in signal
degradation.
