Input Cards

The formatting of the input deck is critical to the operation of voacap and many 'bugs' can be traced to malformed deck. This section defines the formatting of the input deck. ANTENNA This card is used to define the characteristics of the transmit and receive antennas and is formatted as follows;

ANTENNA       1    1    2   30     0.000[harris/[email protected]   ]  0.0    0.4000
ANTENNA       2    2    2   30     0.000[harris/1950BD10.anw  ] 23.2    0.0000

21-25	maxfreq	I5	maximum frequency of operation
	designfreq	F10.3	Antenna design frequency
	antfile	A21	Filepath to the relevant antenna file (relative to the itshfbc directory)
	beammain	f5.1	Antenna bearing (degrees)
	pwerkw	f10.4	Power (kW)
