Connect the male SMA connector on the cable assembly to the mating female SMA connector on the
beacon. For additional protection from corrosion, spray exposed metal surfaces of connectors with
Boeshield T-9 or equivalent waterproof lubricant (not provided).

Antenna installation verification
To verify proper installation of the cross dipole antenna, the following procedure should be followed
(requires two persons, preferably with 2-way radio communications):
•
One person should be on the deck with an FPR-100 with line-of-sight view of the cross dipole antenna.
The FPR-100 antenna should be oriented horizontally and ideally be located directly under the cross
dipole antenna.
•
With the FPR-100 ready to receive a test burst, the other person should initiate a Self-Test.
•
If the FPR-100 successfully receives the test burst, then the cross dipole antenna is installed correctly.
•
The FPR-100 can also verify that the ThunderBird SSAS is programmed correctly.
•
If the test burst was not received, the FPR-100 may be too far from the antenna. Repeat the test with
the FPR-100 closer to the antenna. (Typically, an FPR-100 can receive a signal from the cross dipole
at a maximum range of 100 ft. (30.5m).
•
If the FPR-100 still does not receive the test burst, check all coaxial connections from the beacon to
the antenna.
SECTION 4 - OPERATION
4.1
General
4.1.1
The ThunderBird SSAS beacon can only be activated manually while installed in the mounting bracket.
4.1.2
The following two conditions must be satisfied to activate the ThunderBird SSAS:
1) The switch on the beacon must be placed in the "READY" position.
2) One of the remote activation switches must be depressed.
4.1.3
The ThunderBird SSAS is designed to allow the user to perform periodic testing while SSAS is in the
mounting bracket, to assure a functioning beacon.
4.2
Controls
4.2.1
Thumb Switch: The thumb switch on the top right side of the beacon controls the mode of operation of the
ThunderBird SSAS. There are three switch positions (see Figure 11):
1) Off: Down to the front, indicated by "O"
2) Self-Test: Vertical
3) Ready: Down to the back, indicated by "I"
