Parabolic antennas

Tuesday, 26 July, 2005 | Supplied by:

PacSat Antennas has launched a range of 5.8 GHz solid parabolic dishes. Solid dishes have a number of advantages over parabolic grids - particularly in high traffic: better front-to-back ratio (greater immunity to interference); more uniform and narrower beam-width; more robust than panel-type equivalent.

Despite these advantages, solid dishes are not frequently deployed at 2.4 GHz as the size required to achieve moderate gain can create unacceptable wind-loading on masts. At 5.8 GHz the size of the dishes is not such an issue.

The company's range of solid parabolic dishes now includes 21, 24, 27 and 36 dBi models.

Key features of the three latest models are: spun surface-treated and painted aluminium alloy reflector; solid brass feed in fibreglass housing; stainless-steel mounting hardware; good front-to-back ratios.
