The Telewave ANT280S Wideband Discone Antenna 118 MHz-3 GHz, is a rugged, lightweight, wideband antenna for all frequencies between 118 MHz and 3 GHz. This versatile antenna provides a highly flexible solution to inter-operability requirements in multiple bands.
Each antenna is con struct ed from Mil. Spec. 6061-T6 solid aluminum, weld ed at all joints for maximum strength. A high-strength radome encloses the upper cone and RF connections to ensure survivability in adverse environments. The radome and TxylanTM coating on all metal surfaces ensures complete protection from corrosive gases, ultraviolet radiation, salt spray, acid rain and sand storms in desert environments.
The antenna has a 1.5” diameter mast, and includes an ANTC480 dual clamp kit for mounting to a 1.5”-3.5” O.D. support pipe. The ANT280S is light enough to be used as a tactical antenna for field deployment, and can complement or replace multiple antennas on a mobile command vehicle. The 500 watt power rating allows use of high-power radios and tactical repeaters.
The full-surface coating and rugged construction means it can also be permanently mounted on a tower or command center roof for long-term fixed operation. The ANT280S is ready to operate with a single or multiband radio using one antenna output. Several types of low-loss couplers are available for multi-radio operation.
For optimum performance in the lowest frequency ranges, the antenna should be mounted at least 20 feet above the closest reflecting surface.
