WISCO International (Decibel Products / Dipoles DB264)

DB264 RUGGEDIZED BROAD BAND ANTENNA 6 or 9 dB GAIN, 150-174 and 220-222 MHz

A high gain, lightweight antenna for 150-174 MHz, the DB264 features a 10 MHz bandwidth and an enclosed feed system. Can be mounted on the top or side of the tower.

Broad Response - 10 MHz bandwidth provides optimum performance in single or multi-frequency systems, in both transmit and receive.
Moisture Resistant - VAPOR-BLOC� cable harness is enclosed within the metal mast and the radiating elements, both vented to prevent moisture accumulation.
Circular Pattern - DB264 has four elements positioned evenly, every 90 degrees around the mast, for an omni pattern.
Offset Pattern - DB264E comes with four elements aligned collinearly on the same side of the mast for maximum directional gain.
Two-Piece Mast - For ease of shipment and handling, the mast is made in two sections. A unique center splice assures proper alignment. Cable harness aligns automatically when sections are joined.
Field Changeable - Patterns can be changed with ordinary hand tools.
Lightning Resistant - The radiators operate at DC ground, and the aluminum mast with its pointed cap provides a low resistant discharge path to the tower or ground system.
Ordering Information - Use model number for correct frequency and specify termination if non-standard. DB365-OS Mounting Clamps are included. Order DB5001 Side Mount Kit if needed. For Dipole Stabilizer Kit, order 12088 (four required). Other size clamps can be special ordered. Example: DB264-A for 150-160 MHz range. Order jumper cable separately, if desired.
