Extreme Interference Antenna
The 26000 series antenna is designed for interference levels in the Global Positioning System (GPS) band and offers high, narrowband filtering that eliminates the fundamental interference at lower frequencies. The antenna has a high front-to-back ratio null to attenuate the narrowband third-order harmonic. A tilt bracket can be provided to accurately position the antenna for maximum signal enhancement. In addition, the unit has eliminated the flywheeling (lost lock) of GPS timing clocks. The antenna is designed for use in PCS, code-division multiple access (CDMA) and time-division multiple access (TDMA) transmit sites to synchronize data transmission.

2.4 GHz ISM Antennas
The MPR-2400 series 2.4 GHz ISM antennas comprise three parabolic reflector models with 20, 22 or 24 dBi gain for long-range point-to-point communications. The units operate in the unlicensed 2400 to 2483.5 MHz frequency band and are wind load rated for 110 miles per hour when covered with a half-inch of ice. The MYP series 2.4 GHz Yagi antennas also operate from 2400 to 2483.5 MHz and offer 8.8 to 13.5 dBi gain, good performance and economical cost for use in point-to-point or bridge applications. The MFB-2400 series omnidirectional site antennas are available for applications such as wireless data collection and inventory systems that require wide-area RF coverage. The series includes three omnidirectional site antennas offering varying amounts of gain and 100 MHz bandwidth that covers the 2400 to 2483.5 MHz ISM band. Portable and single-phasing coil mobile antennas also are available.

Linearly Polarized Single Patch Antenna
The model S9029HVP ISM antenna provides simultaneous reception and transmission of both vertically and linearly polarized signals in the 902 to 928 MHz frequency band. Good electrical performance is achieved due to the high quality etched copper circuitry that improves data transmission. The antenna consists of a single broadband microstrip patch that provides 9 dBi gain with a nominal 55° x 60° half-power beamwidth. SWR is 2 and impedance is 50 W. The housing is vacuumed formed out of polyvinyl chloride in a UV-stabilized, weather-resistant radome. Size: 10" x 11" x 1". Custom configurations of radome finish, color and texture can be provided to complement and blend within any environment.

Dual-slant Cellular Antennas
These dual-slant 45° polarization diversity base station antennas maximize footprint coverage and provide good performance with horizontal beamwidths of 65° and 85°, peak gains ranging from 8 to 16 dBi and at least 30 dB port-to-port isolation. Front-to-back ratios of = 25 are easily realized with the company’s patented planar patch technology. The antennas and optional mechanical downtilt bracket hardware have passed wind tunnel testing to 125-mile-per-hour survivability. Wall, tower or roof-top installations can be easily camouflaged by painting the antenna.
