TetraAnt 5 13 35
TetraAnt 5 13 35 - matching, VSWR
The sweep frequency is 5.0 - 6.0 GHz. As you can see, the VSWR is better than 2.0 at the frequency band 5.0 to 5.75 GHz.
For measurement the random sample of two antennas was chosen.
TetraAnt 5 13 35 - the antenna gain
This figure shows the realized gain of the antenna. It takes into account all antenna's losses - it was measured at the connector reference plane.
Antenna effectively works up to 5.9 GHz where the gain is 12 dBi, but please note the VSWR = 3.0 for that frequency.
The antenna gain was measured in the slant ranges, with a two-antenna method.
TetraAnt 5 13 35 - Directional Patterns in Polar Coordinates
Patterns are referenced to 0 dB, the full scale is 40 dB. Frequencies are: 5.15 - 5.4 - 5.6 - 5.75 - 5.85 - 5.95 GHz.
TetraAnt 5 13 35 - Specifications
Peak Gain is the maximum value of the gain over the operational frequency range. For Elboxrf TetraAnt and Standard antennas the gain is so called realized gain that takes into account all possible antenna's losses.
HPBW stands for half power beamwidth.
VSWR stands for voltage standing wave ratio and is figure of merit of matching quality to the load impedance.
XPD stands for cross polar discrimination.
