Poynting Antennas procured its own die-cast moulds to manufacture a gridded parabolic reflector. The 90cm reflector yields a 2.4GHz grid with gain of 26-27dBi which is about 3dB higher than equivalent products.
The gain at 5GHz is an equally impressive 31dBi since the reflector was designed from the outset to operate at the higher band as well. Poynting is now one of the few companies worldwide that has invested in their own tooling for such an antenna type.
The new parabolic 90 x 70cm aluminium grid antennas are considerably lighter than our previous grid dishes. The design is such that the grid is moulded in two halves (split-design), which results in a 65% reduction in packaging volume. Most existing grids do not work well in the 5 - 6GHz band due to their use of 2.4GHz reflectors, whereas 5GHz operation was part of the design parameters of the Poynting grid.
The feed design also optimises aperture efficiencies which gives significantly higher gain when compared to similar grid antennas.
Features:
* UV-resistant powder coat finish
* Rugged outdoor construction
* Quick and easy installation
* Lightweight and low wind resistance
* Azimuth and elevation continuous adjustment
K-GRID-003-05
This 2.4 - 2.8GHz antenna achieves up to 27dBi gain and a VSWR less than <2.0:1.The electrical performance is considerably better than many competing products that manage only 24dBi at 2.4GHz in grids which are generally unsuitable for operation at 5 - 6GHz. This antenna's dimensions are 90cm x 70cm, with a focal length of 30cm, and weighs 3.28kg.
Please note that the antennas are sold in packs of five only, at a retail price of R3 100, of which the price per unit (excluding VAT) is R620.
K-GRID-003-06
This 5 - 6GHz antenna achieves up 31dBi gain and a VSWR over <2.0:1 of the band. This antenna is unique in its excellent performance at the high frequencies since the grid density was from the start optimised for use in this band. Many earlier competitors used 2.4GHz reflectors which "leaks" considerable energy when used in the 5GHz band.
Both antennas are ideal for long range, ultra-secure wireless LAN point-to-point communication and long range CPE installation. They can also be used as client antennas in a wireless network or in similar proprietary standards operating in the 2.4 - 2.8GHz or 5 - 6GHz frequency bands.
This high frequency antenna's dimensions are 90cm x 70cm, with a focal length of 30cm, and weighs 3.28kg. Please note that the antennas are sold in packs of five only, at a retail price of R3 200, of which the price per unit (excluding VAT) is R640.
