Antenna
The antenna is used with the Axis
3
to acquire the GPS, L-Band,
300 kHz beacon and WAAS signals concurrently.
The antenna supplied with the Axis
3
receiver provides radio
frequency signals to all internal receivers. The enclosure houses
an L-band antenna for GPS and L-Band satellite signals and
anH-field beacon loop antenna for beacon signal reception.
Both antenna elements are active during operation and draw
power from the Axis
3
receiver. All three signals are transmitted
from the TNC connector on the antenna to the receiver’s
antenna (RF) port. The Axis
3
automatically routes these signals
to the appropriate internal sensor.
CAUTION
Do not connect or disconnect the antenna while the system
is powered up. This could damage the system.
