Appendix D: Antenna
An antenna is the radiating and receiving element from which the radio
signal, in the form of RF power, is radiated to its surroundings and vice
versa. The transmission range is a function of the antenna gain and
transmitting power. These factors are limited by country regulations.
The WinLink may be operated with an integrated antenna attached to
the ODU unit, or with an external antenna wired to the ODU via an N-
type connector. All cables and connections must be connected correctly
to reduce losses. The required antenna impedance is 50
Ω
.
