1
Cable loss (dB)
The signal strength loss introduced by the cable connected to the antenna expressed on the
decibel logarithmic scale.
Net gain (dBi)
The resulting amplification of the antenna paired with its cable.
Polarization
The orientation of the electrical field which the antenna is optimized to receive. If the transmitting
and receiving antennas are both linear polarized, then turning one 90° so that they are cross
polarized will reduce the range significantly.
VSWR
Voltage Standing Wave Ratio (VSWR) is the ratio of maximum voltage to minimum voltage along the
line. Expresses the degree of match between the transmission line and the terminating element
(antenna). When VSWR is 1:1 the match is perfect, a VSWR of 1.5:1 corresponds to 96% power
efficiency.
Azimuth 3dB Beamwidth
Width of the antenna beam on the horizontal plane expressed in degrees.
Elevation 3dB Beamwidth
Height of the antenna beam on the vertical plane expressed in degrees.
