THE ANTENNAS CONSIST OF:
· A parabolic aluminium reflector. The outer surface is spray painted. Standard colour is RAL7038.
· An antenna mount.
· A low VSWR antenna feed. A smooth continuous polarisation adjustment may be performed. The feed horn is sealed for pressurisation.
· An optional spherical radome for environmental protection.
The electrical specifications are given in the Radiation Pattern Envelope for each type of antenna. This specification is a maximum curve, which is derived from actual measurements.
A three dimensional chart specify the cross-polarisation performance close to the main lobe of the antenna. The off-axis cross-polar sidelobes are given in the individual RPE.
Tabulated values of the main characteristics are given for all frequency bands and diameters.
