WISCO International (Decibel Products / Fiberglass

DB812K and DB812KF (flange) antennas provide Decibel's highest omnidirectional gain and power rating for 800/900 MHz applications. Radiators are enclosed in a 3" (76.2 mm) OD Horizon Blue^� radome made of Minimum-Tip-Deflection� (MTD�) fiberglass, which resists high winds with very little tip deflection.

Broad Response - Antenna models fulfill frequency requirements for conventional, trunked, paging and cellular communications.
Sturdy Construction - In addition to MTD fiberglass radomes, the antennas have weather-resistant masts made of strong 6061-T6 aluminum alloys.
Very Rugged - The antennas resist winds to 150 mph (241 kph). In 100 mph (161 kph) winds, tip deflection is 10� maximum.
Reliable - Each antenna is tested for 500 or 750 watts (DB812KF) power rating compliance and the absence of intermodulation generators.
Engineered to Last - All metals used in radiator, feed and matching systems are copper or brass, which minimizes galvanic reaction and reduces intermodulation.
Lightning Resistant - A DC ground is provided.
Moisture Resistant - Top and bottom removable drain plugs are provided.
Ready to Install - DB5091-3-No-Torsion Mount and VAPOR-WRAP� are provided.
Ordering Information - Use model number for correct frequency and options if desired. Mounting clamps and VAPOR-WRAP� are included. Order jumper cable separately, if desired.
