BROAD BAND YAGI ANTENNA 9.5 dB GAIN, 150-174 and 220-222 MHz

Broad Bandwidth - 10 MHz gives optimum performance in either single or multi-frequency systems.
Weather Resistant - The feed is enclosed within the dipole assembly for added protection from ice and snow.
Lightning Resistant - All elements are grounded.
Stacked Arrays - Two antennas proved 12.5 dB gain, four antennas 15.5 dB. A Vertical spacing of .75 to 1.0 wavelengths between antennas is recommended.
Key Applications - DB292s are ideal for systems in need of broad band coverage, protection against severe environments, high gain in a narrow sector or reduced interference on the backside of the antenna.
No Field Tuning - Antenna is adjusted at the factory for minimum VSWR.
Rugged - DB292 is made of aluminum alloys and reinforced with .875" (22.26 mm) sockets at the boom. Brackets and hardware are galvanized steel.
Ordering Information
Use model number for correct frequency and specify termination if non-standard. Brackets and clamps are supplied. Other size clamps can be special ordered.

Examples: DB292-A, or 2 ea. DB292-A plus 1 ea. 14292-2-A for dual array. Order jumper cable separately, if desired.
