Transmit-Antenna Browser

The Transmit-Antenna Browser is a window with a grid like display of the transmit antennas added using the "Xmtr Antennas" page of the Circuit-Configuration Manager.

The Transmit-Antenna Browser makes it easy to see and compare several transmit antenna configurations and select between them.

This is a browser only, meaning users must add, edit and delete transmit antenna groups using the "Xmtr Antennas" page of the Circuit-Configuration Manager.

These same transmit-antenna groups are also used to configure circuits with the Prediction-Batch Manager.

Note - Changing the selected Antenna group in the Transmit-Antenna Browser causes the newly selected group to become the default for all prediction types except Prediction Batch. This change is, of course, also shown in the Circuit-Configuration Manager.

Group Name: This is the user-entered name and should help easily identify the group.

Antenna Filename: This column shows the selected antenna file name.

Max Freq: The maximum frequency for which this antenna will be used. The available frequency range is 3-30 MHz. These frequencies may not overlap. When more than one antenna is configured the "Min", beginning, frequency of the second antenna will be the "Max, or ending, frequency of the first, etc. In other words, this is the antenna ending frequency; when more than one antenna is used (for the frequency range considered) this value also indicates the starting frequency for the next antenna.

Gain: For an Isotrope type antenna, the default, this is the gain in dBi. Alternatively, this field holds the design frequency, in MHz. A zero, will force the design frequency = operating frequency (if appropriate).

Az: The main beam azimuth bearing of the antenna in degrees from North. The Az range is 0-360 in the clockwise direction; for example East = 90. In other words, what is the "true bearing", East of North of the antenna main beam in degrees? In WinCAP Wizard you can force the transmit antenna to point directly at the receive target by entering -1; the correct azimuth is then calculated before being passed to the VOACAP engine.

Transmit Power: The transmit power in kilowatts delivered to each antenna should be specified. For example 0.1 is 100 watts. The available power range is 0.001 to 9999.99.

Note the "status line" provides a brief description of each parameter as the mouse cursor passes over.

The Transmit-Antenna Browser window size is adjustable to suit the user.
