ENG/OB Van Transmit Antennas  Vislink News and Entertainment offers two different models of an off-set fed, lightweight asymmetrical ENG/OB van antenna, both constructed of compression moulded fibreglass with integrated reflective surface. The ProStar 2A20 and Ellipse 2000 feature the latest in solid-state switching technology for the polarization selection. The elimination of all coaxial RF relays also reduces the DC operating power and provides greater polarization isolation due to the enhanced phase matched printed circuit board design. Both antennas are available in either single band (1.9 – 2.5 GHz, or 6.4 – 7.125 GHz) or dual band (1.9 – 2.5 GHz and 6.4 – 7.125 GHz) configurations and come equipped with quad polarization (CW, CCW, V, & H).
2A20SS / 7A30SS Key Features- Gain: 20 dBi @ 2 GHz, 30 dB @ 7 GHz
- RF switching performed through the latest advancements in solid-state technology— no electro-mechanical switches
- High reliability, lower cost of ownership, less down time than electro-mechanical switch designs
- Smaller, lighter weight feed design
- Dramatically lower DC operating power
- Quad polarization standard
- Excellent front-to-back and sidelobe performance
- Low-profile, offset-fed design
- High degree of integration through the use of custom integrated
Ellipse 2000 Key FeaturesSame as above plus: - 3 to 4 dB additional gain over the traditional 2A20/7A30 (50% additional range)
- Gain: 23 dB @ 2 GHz, 34 dB @ 7 GHz
- Superior front-to-back and side lobe performance
