DCR-MFE “Funky Elbow”

• Variable spacing
• Broad bandwidth capability
• Array input power 100kW or more
• Series fed for multi-station operation
• Circularly polarized
• Stainless steel construction
• Low ice sensitivity
• Fine matcher included
• Match bay spacing to existing tower for more consistent pattern results
• Radomes/deicers available

The DCR-MFE antenna is center fed, meeting the needs of high power, high
bandwidth and short spaced bay requirements.
Variable Bay Spacing
Through the use of a series feed system, proper RF phase to each bay is
maintained, even at reduced bay spacings. This allows for bay spacings
between 1/2 and full wavelength. The reduction in bay spacing can have
multiple benefits including: 1) A significant reduction in the amount of
“downward” radiation. 2) Broader elevation beam. 3) More constant patterns.
It must be noted that reducing the bay spacing for a given number of bays
also reduces the gain. An 8 bay with full wavelength spacing has a gain of
4.3x. The elevation pattern of an 8 bay half wavelength with a gain of 2.4x
resembles the elevation pattern of a 4 bay full wavelength in terms of beam
width and gain. A variety of bay spacing is available; contact factory for details.

High Power Input Capability
The DCR-M is designed with input line sizes up to 6-1/8″ EIA. This allows for
array input power levels in excess of 100kW.
Beam Tilt and Null Fill
Beam tilt and/or null fill are options typically offered in arrays of eight bays or
more, however they may also be utilized on smaller arrays.
Directional Arrays
The DCR-MFE antenna is available in directional arrays which are custombuilt
to the needs of the specific station.
Multi-Station Operation
The high power handling and wideband characteristics of the DCR-MFE make
this antenna an excellent alternative to high cost panel antennas.
