Operating mode
Once the antenna is installed, the operating mode
is chosen. The antenna has two operating modes:
passive and active, if power is supplied.
PASSIVE MODE: Without power, the antenna
works like a passive antenna, capturing UHF and
VHF signals. Operating mode suitable for locations
near repeaters where the signal level is good.
ACTIVE or intelligent MODE: When providing
power supply (12V ), the antenna amplifies the
received signals in both UHF and VHF bands. This
operating mode is recommended for locations
where the received signal level is poor.
