9. Radio Antenna

The radio antenna is required for operation of ECW100. It's an external λ/2 dipole
antenna with 3 m cable (50 RG-174U on conventional SMA), for internal or external
installation.
The correct installation has a considerable effect upon range for transmitter/receiver
range, so the installation must be carefully considered. The antenna must be vertical,
allowing generally unobstructed radiation to the front and sides. Horizontal or inclined
installation is not acceptable. In particular, there should be no electrically conducting
surfaces (metal, carbon fibre) above or immediately alongside the antenna.
This antenna doesn't need a ground plane.
Installation may only be in a Zone 2A or 3 as described in DO-160E Section 23.
