The DCR-S/HDR-S has been used extensively for high power broadband
applications. The “S” series antennas are circularly polarized with a power
rating of 28 kW for a single bay and is available in stacked arrays of up to 16
bays with an input rating to 120 kW. For situations where ice formation is
common, the arrays can be equipped with optional electrical deicers or
radomes. The antenna is DC grounded and does not require shorting stubs.
Each array is supplied with an input fine matcher for field optimization. For
reduced down-ward radiation, the use of a custom feed design allows for
shorter spacings in a series fed configuration.
High Power Input Capability
The DCR-S and HDR-S were designed to handle high input power ideally
suited for multiplexing. The “S” series antenna is available with optional
4-1/16“ feed system having a power input rating (for five or more bays) of
70 kW. Arrays with 6-1/8” inputs are also available.
The wide bandwith and the high power input capability of the “S” series
antenna permits optional multi-station operation.
Beam Tilt and Null Fill
Beam tilt and/or null fill are available options. These options are ordinarily
specified for arrays of 8 bays or more. Even numbered arrays of six sections
and fewer may include one or both options and typically are designed as a
center-fed array. The “S” series antenna is available in directional arrays which
are custom-built to the needs of the station.
The four-dipole-per-element design offers the advantage of more symmetrical
azimuth pattern performance and H/V ratio than dual dipole designs,
providing more rubust coverage.
