DB580 Side Mounted

The economical DB580 with unity or 0 dBd gain and DB583 with 3 dBd gain are omnidirectional antennas for 800/900 MHz applications. Radiators are enclosed in a 1.5" (38.l mm) OD Horizon Blue^TM radome made of Mirage extruded fiberglass.

Broad Response - Three models of each are designed for 800/900 MHz conventional, trunked, paging and cellular communications.

Dual Purpose Mount - New integral mount made of cast aluminum alloy mounts to the side or top of a pipe.

.
Reliable - Each antenna is tested for 500 watts power rating compliance and the absence of the intermodulation generators.

Moisture Resistant - The bottom cap has a moisture-sealed bulkhead N-Female connector, and a removable drain plug is located at each end of the antenna.

Lightning Resistant - A DC ground is provided.

Ready to Install - Since the transmission line of any length can be connected directly to the antenna (and dropped through the mounting pipe), no jumper cable is furnished.

Ordering Information - Order DB580 for unity gain and DB583 for 3 dBd gain. Use model number for correct frequency. Order jumper cable separately, if desired
