This series of panel antennas are ideal for four-sided array design to provide customized coverage for single or multistation use in Band III. Model 655 has a nominal gain of 8 dBd and can be used for horizontally polarized services. Model 656 is horizontally polarized and provides a nominal gain of 11dBd.
Construction from a thick-walled tube and solid steel bar gives a heavy-duty panel which is designed for operation in very harsh environments. This design also ensures ideal hot-dip galvanizing for optimum corrosion protection. Colours are available for aviation visibility and even further corrosion protection.
The coaxial feed system can be fully pressurized and features twin "O" ring seals on the feed point insulators. The panels are tolerant of light icing (radomes are available for use under heavy icing conditions down to -40 degrees C) and have a very low VSWR (typically less than 1.05:1) over the entire 174 - 230MHz band depending on the system configuration.
These panels are ideal array elements having low sidelobes, low mutual couplings between panels and high power ratings across the full band. This results in complete antenna systems that have very wide VSWR and pattern bandwidth.
The ability to utilize larger tower cross-sections allows support for a top-mounted UHF antenna such as the PHP or PVP UHF antenna arrays. This provides a powerful combination for delivering DTV and/or DAB systems customized to suit the coverage requirements of the customer.
