High Performance
Single polarised

The ARTA HP antennas are designed for use in PDH and SDH radio relay systems where there are high demands for sidelobe suppression and front-to-back ratio.

Great care is taken in design to achieve optimal electrical and mechanical performance.

The increased antenna gain antennas may improve system margins or reduce the need for larger antennas.

The antenna are single polarised and comply with ETS 300 833 Class 3.


The antennas consist of:
• A parabolic aluminium reflector with a shield for sidelobe suppression.
  The outer surface is spray painted. Standard colour is RAL7038.

• A hot dip galvanised steel antenna mount.

• A buttonhook type, low VSWR antenna feed. The feed horn is sealed for pressurisation.
  A smooth  continuous polarisation adjustment may be performed.

• A flexible radome for environmental protection.

Electrical specifications
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.
