Typical Antenna Gain / Factor
This is calculated by reference to standard gain horn antennas, and cross checked with reference to the antenna beamwidth, with an estimated error of +/- 0.8dB.
Patterns measured using a linear source antenna , Horizontal / Vertical refers to the polarisation of the source horn.
On patterns the Red & Black trace = Horizontal polarised source, Green & Blue trace = Vertical polarised source
Pattern Cut Definition
Patterns are measured using a linear source antenna. The polarisation refers to the electric field polarisation of the source antenna.
Horizontal Cut (Cut 1) Vertical Cut (Cut 2)
Antenna viewed from back
Horizontal source polarisation Vertical source polarisation
On the typical antennas patterns shown above the :
- Red trace = Sweep with horizontal source polarisation and antenna under test in horizontal cut (cut 1)
- Blue trace = Sweep with vertical source polarisation and antenna under test in horizontal cut (cut 1).
