E. Antenna Mechanical Installation
(1) Antenna installation is critical to the range and quality of the transmitted signal.
Care should be taken to keep all antennas a separated as possible. A minimum of
70 cm should be observed if possible.
(2) Whenever possible, mount antennas on the bottom of the aircraft. The only
exception is if two antennas covering the same frequency band are used, put one
on the top of the aircraft and the other on the bottom to achieve maximum isolation.
If this is not possible, put on the front of the aircraft and one on the rear.
(3) The antennas should be mounted on a flat metal surface to obtain a proper ground
plane. Ensure the antenna is adequately grounded to the aircraft skin (<5 mohm is
a standard rule of thumb).
(4) P-2000/RT-2000 antennas should be mounted a minimum of 20 cm from each
other.
(5) Wulfsberg recommends the use of RG-193 on most installations. Installers can
substitute other types of coax than RG-193 to get better performance especially at
higher frequencies. Be aware that each type of coaxial cable requires specific
connectors that may only be available from the coaxial cable manufacturer.
