antfactor_from_gain

pycraf.conversions.antfactor_from_gain(gain, freq, zi)

Antenna factor from antenna gain, given frequency and impedance.

Parameters:

gainQuantity

Antenna gain [dBi, or dimless]

freqQuantity

Frequency [Hz]

ziQuantity

Receiver impedance, Zi [Ohm]

Returns:

antfactorQuantity

Antenna factor, Ka [dB(1/m)]

Notes

Because all parameters/returned values are Astropy Quantities (see Quantity), unit conversion is automatically performed.
