659 174-240MHz TV/DAB Panel Arrays 659, 660 Series
This series of panel antennas are ideal for four-sided array design to provide a customized coverage for vertically polarized use in Band III. Model 659 has a nominal gain of 8dBd and the model 660 has a nominal gain of 11dBd. Construction from a thick-walled tube and solid steel bar gives a heavy-duty panel that is designed for operation in very harsh environments. This design also ensures ideal hot-dip galvanizing for optimum 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 our 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.

Note 1 Power rating is limited by the input connector type. 3kW for 7-16 DIN, 4kW for 7/8" EIA. Note 2 The 659 antenna has been primarily designed as a vertically polarized array element where low levels of mutual coupling exist between vertically stacked radiators. It may be used as a horizontally polarized panel in situations where a single bay (or level) of panels is used. This will provide a better array VSWR in that circumstance. Where multiple levels of horizontally polarized antennas are needed, the 655 panel is recommended.
