    Chapter 2 Mounting the Units Installation Description Correct installation of the equipment is important for maximum performance and reliability. Antennas and earth connections must be installed with the greatest care using corrosion resistant materials. Cable routing shall be made so the cables are protected from physical damage. Sharp cable bends especially on coaxial cables must be avoided and a sufficient number of clips or straps should be used to secure the cables.

    Ground connections Ground connections 2.3.1 Antenna Tuning Unit As the earth connection of a transmitter is a very important part of the antenna system, it is of the utmost importance to keep in mind that the earth connection of the Antenna Tuning Unit must have the lowest possible RF-impedance.

  • Page 25: Grounding Considerations

    Grounding considerations Grounding considerations Proper system grounding is one of the most important installation details. Two areas of grounding must be considered: a) The ground connection between the ATU and earth plane. b) The ground connection of the TU and the externally connected equipment. Each area requires separate considerations even though they are interrelated.
  • Page 26 Grounding considerations 2.4.2 RF ground loop It is not always possible or practical to mount the ATU using a very short strap to the actual ground- plane. In such a case the coaxialcable may be connected between units with different ground potentials causing RF loop-current to flow.

    Antennas Antennas 2.5.1 Transceiver Antenna The equipment is used with common transmitting and receiving antenna. The antenna should be erected in the open, away from conducting object such as derricks etc. which may cause reduction of the radiated power. Insulators should be of the best type having low leakage even when wet. Stays, wires, steel masts etc.

The antenna should be erected well in the clear and kept away as far as possible from electrical equip- ment in order to minimize noise. Electrical installation such as cable braiding and instruments in the vicinity of the antenna should be earthed effectively, and the instruments in question should be fitted with noise-interference suppression devices, effective in the range 0.1 to 30 MHz.
