DM1601354
The DM 1601354 L-Band Antenna has been designed for BCAS characteristics to provide more stringent radiation pattern directivity to assure reliable system performance. Features of the DM NI50-Series have still been retained to provide: Extremely high side-load strength guards against breakage by ground handling gear.Completely sealed construction prevents failure from moisture incursion.Lightning protection circuits prevent damage to antenna and saveguards electronic equipment. | Frequency Range: | 960 to 1220 MHz | | VSWR: | 1.8:1 at 960-1220 MHz
1.42:1 at 1000-1100 MHz | | Gain: | See Below | | Impedance: | 50 Ohms | | Polarization: | Vertical | | Power (CW): | 250 W CW | | Power (Peak): | 3 kW | | Radiation Pattern: | See Below | | dc Resistance: | Short Circuit | | Boeing Part No.: | S22OT116-101 | | Connectors: | "C" Female | | Weight: | 0.32 lbs (0.15 kg) |
RADIATION PATTERN and GAIN
The radiation pattern is an adjusted omnidirectional pattern. It has some directivity in the forward direction to improve the gain in the most needed forward direction for ASAS, BCAS, and TCAS. This adjustment in pattern and in gain purposely improves the reception and transmission characteristics while still meeting the following ARINC characteristics:
- 709-1 (DME)
- 718 (ATC Transponder)
- 730 (ASAS) By making the radiation pattern slightly eccentric rather than perfectly omnidirectional, the forward gain approximates that of a vertically polarized quarter wave stub. the rearward gain is within 2.5 dB below the forward gain.
