  • Page 65 12.12. Propagation of SW Signals One of the questions raised frequently is to determine which transmissions can be received at what distance from the transmitter. There are a number of factors that affect short-wave reception and distance vary greatly depending on time of day and year, sun activity and amount of traffic in a particular band.
  • Page 66 12.13 Reception Antennæ onboard Vessels Radio receivers are today standard equipment on board sea-going vessels. In most cases it is seldom taken into account, that every receiver, no matter how expensive it is, can only function as good as its antenna. What should one take into consideration when choosing an antenna? The frequency range of the antenna must have the same range as the receiver, at least have the same range that is going to be used.
  • Page 67 Alternatively an active antenna can be used. The input resistor in the amplifier of an active antenna is very high, therefore it requires a very short whip. The output resistor of the amplifier is 50 throughout the whole of the specified frequency range, so that a corresponding coaxial cable also with 50 which transmits the signal from the antenna without further loss of adaptation.
