AValonRF Presents and demonstrates it’s "No Moving Part" Tracking Antenna Receivers at the AUVSI meeting in San Diego

San Diego, CA February 17, 2005 – AValonRF, Inc., Will present and demonstrate it’s “no moving part”, Tracking Antenna receivers, Tuning Range - 460MHz-2.5GHz, C Band, KU Band, at the AUVSI chapter meeting in San Diego on February 24, 2005.
The TA04, TA08 and TA16 are a family of passive tracking antenna systems designed for video links to/from moving platforms that are tuned to any frequency band in the spectrum from 300MHz to 2.5GHz. Higher frequencies are available using external up/down converters. Tuning is via a RS232 port or via a remote control.

The AUVSI Lindenberg chapter meeting and luncheon will take place on Thursday, February 24, 2005, 11.30a.m. – 1.00p.m. , PS Business Park Conference room,
3954 Murphy Canyon road, suite D200, San Diego, CA.

Hoa Nghuen of the SSC Robotics Lab, San Diego, will present Unmanned Ground Vehicle (UGVs) work in progress at the Robotics System Works SSC SD, Code 2731, Robotics Systems Branch, www.spawar.navy.mil/robots/
RSVP to Ed Henning, ehennig@tamasco.com, Phone 858-496-0600

The TA system selects the antenna that has the best reception automatically and provides direction indication.

They include an array of 4,8 or16 (CP or LP) high gain antennas, cables, one, two or four DX04 series receivers and a DX002 or DX004 baseband diversity selector

Advantages of the Tracking Antennas:
· Extends the range of UAV/UGV/USV links 6:1 to 128:1 with (versus OMNI directional antennas) no moving parts and without increasing transmitter power.
· Works on vehicles and small boats in motion. No need to stop.
· Eliminates the need for direction finding.
· Small and low weight
. Tuning range - 460MHz-2.5GHz, C Band, KU Band

AvalonRF will also present and demonstrate its Wireless Digital Links for Unmanned Ground Vehicles – UGV, UAV, Micro UAV, USV and Robotics.
