Beamwidth antennas

Wednesday, 27 April, 2005 | Supplied by:

Three broadband 90° beamwidth mobile antennas have joined Radio Frequency Systems' optimiser family.

The additions - the variable electrical tilt APXV18-20914 and APXV18-20915 and the fixed tilt APX86-909014L - complete the 90° aperture series.

All three antennas are broadband, with the APXV18-20914 and APX18-201915 supporting frequencies in the 1710 to 2170 MHz band, while the APX86-90914L accommodates frequencies in the 806 to 960 MHz band.

As a result, the APX86-90914L supports trunking/specialised mobile radio, 800 MHz, and (GSM) 900 MHz services. The APX18-20914/15 antennas support GSM 1800 MHz, (PCS) 1900 MHz and (UMTS) 2100 MHz services.

All three antennas exhibit performance characteristics common to all members of the optimiser family. This includes side lobe suppression typically better than 20 dB across the entire frequency and tilt range, increased gain and good front-to-back ratio.
