The DCR-M/HDR-M has been used extensively for high power broadband
applications. The “M” series antennas are circularly polarized with a power
rating of 18 kW for a single bay and is available in stacked arrays of up to
16 bays with an input rating to 40 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 “M” 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 w/
6-1/8” inputs are also available.
Multi-Station Operation
The wide bandwith of high power input capability of the “M” 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 “M” series antenna is available in
directional arrays which are custom-built to the needs of the station.
Quadrapole Design
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.
Low downward radiation options available — contact factory.
