Up to 4 independent antenna model
files can be merged in the PRO version.
To merge a new antenna into an
already open file, you will need to use the on the
tool-bar,
And then select the new
antenna from one of the directories you are using. You can add other
antennas as required (max 3 to the original one).
After merging the individual
antennas into a common file:
- All the wires and loads of each of the antennas are
taken into account during calculations.
- However, any editing of the combined antenna model
(move, rotate, edit wire, etc) has to be performed on individual
antennas by first selecting the required antenna you wish to edit using
the A1 to A4 buttons on the bottom left hand side of the main screen (
see next image ).
The following two screenshots
describe the management of the merged files. The example below
(available in
\ANT_PRO\4.maa,) is the "Multiple
3-band quad" merged with a "VHF Yagi Uda",
and consists of four separate antennas. The highlighted antenna (shown
in black) is the Uda-Yagi.
The Adding & Deleting Antennas Function within
the Pro version Program:
- The button
is only enabled when the number of
merged antennas in the opened *.maa file is < 4. If the opened
file already has 4 separate antennas as in the previous quad- Yagi-Uda
antenna, then
is disabled because there is no room
for the new antenna.
- After clicking
of button, specify
which antenna you want to add to the existing model.
- The button
is only enabled if the
current model has 2 or more separate antennas. In the above example the
is highlighted and the selected antenna (Uda-Yagi) will be removed.
- The height of each antenna is taken into account in
the merged file when the calculations are performed i.e. each antenna
is treated separately.
Working with a merged antenna model:
- View Screen:
all antennas except the one selected, are depicted in blue.
If the current box is checked on the view screen then all the
calculated antennas currents will become visible.
- o Antenna Selection Panel
(bottom left hand side) is used to select which antenna will be shown
in the Geometry Tab, and Wire Edit and Element Edit screens.
- Geometry
Screen: only shows the wires of the selected antenna
on the View Tab. Each geometry line entry is prefixed with an Index
number of an active antenna (A1, A2, A3 or A4) i.e. A3/23 (23rd wire of
third antenna).
- Geometry
Screen
- Antenna Selection Panel
(centre right hand side) is used to select which antenna will be shown
in the Geometry Tab.
- The Wire Edit
& Element Edit tabs
will activate pop-up windows, and each one will only display the
selected antennas wires or elements.
- All commands of Main menu and
submenu Edit affect only selected antenna.
- When one of the merged antennas is selected, the
corresponding source is activated together with the selected frequency
for that antenna.
- You can roll back to the previous values of the
antennas parameters after a calculation by using the Undo
button on the tool bar.
- Undo can only perform after
calculating the change to the model; otherwise the feature will be
inactive.
- You can perform a Redo after an Undo
to return to the new calculated model. This feature is only active if Undo
has been performed first.
- The number of steps undo-redo is only limited
capacity hard drive.
- The Undo and Redo
arrow symbols are shown on the toolbar in the following screenshot.
- The Pro version automatically checks the model prior
to executing the calculation. It checks the model for errors: such as
the same and / or crossed wires unacceptable in the method of moments.
- These checks are carried out for all antennas in the
combined model.
- If errors are discovered these are displayed in the
information window, which provides a description of the error. The Tab
key can be used to move the cursor to the problematic wire.
- If a few errors, the first specified first, since its
elimination - the second, etc.
- The following screenshot shows an example message for
combined antenna model where the 28th wire of
the first antenna intersects the 12th wire of
the second antenna.
