Using several examples from simple to complex we will show SMD configuration. The examples were chosen to
show as many varied situations as possible. The RF boxes used were chosen from real products available off
the shelf with no preference to any manufacturer.
Each configuration must start with detailed setup description. In our first example we will show how to configure
SMD for one radio with two independent receivers with various kind of antennas and interactions.
As a first we need to list all antennas and provide for each antenna several parameters given by manufacturer
and its physical installation like frequency coverage for RX and TX, control requirement, assignment to a
particular position (tower) and rotator, RX safe attribute if antenna can be used for receiving while other station
transmits on the same band, and special requirements if exist.
Antennas:
UltraBeam 4 EL YAGI
1.
Frequency coverage RX/TX: 40-6m
RX Only: NO
Control: Original controller
Rotator: PST-51D
Placement: Tower 1
RX safe: NO
Special requirement: Antenna must be able to operate in phase with either or both SteppIRs.
Note: None
SteppIR 4 EL YAGI #1
2.
Frequency coverage RX/TX: 40-6m
RX Only: NO
Control: Original controller
Rotator: Fixed to Rotary tower
Placement: Tower 1
RX safe: NO
Special requirement: Antenna must be able to operate in phase with UltraBeam, the other SteppIR, or
both. In addition, it should be able to operate out of phase with the other SteppIR.
Note: None
SteppIR 4 EL YAGI #2
3.
Frequency coverage RX/TX: 40-6m
RX Only: NO
Control: Original controller
Rotator: Fixed to Rotary tower in same direction as SteppIR #1
Placement: Tower 1
RX safe: NO
Special requirement: Antenna must be able to operate in phase with UltraBeam, the other SteppIR, or
both. In addition, it should be able to operate out of phase with the other SteppIR.
Note: None
