RX 5000

Self-Supporting Wide-Band Receiving Whip Antenna for the LF, MF and HF Bands.

  1. This antenna provides a very efficient means of establishing a universal, wide-band 50 Ω receiving aerial system for the complete LF, MF and HF bands in one unit.
  2. The antenna consists of a high-capacitance, 5 m long glass fibre antenna element with a frequency-compensated wide-band impedance transformer mounted in the bottom end.
  3. The transformer converts the widely varying antenna impedance to a constant 50 Ω, making it possible to use length-independent, shielded, standard RG 58 C/U or RG 213/U as downlead cable to the 50 Ω receiver.
  • The antenna is protected against noise pick-up running on the outside of the downlead cable, and it is protected against static by DC-grounding.
  • Moreover, the 50 Ω receiver and the matching transformer itself are protected against RF overload and violent discharges by an air spark gap (approx. 1 kV), a gas filled spark gap (90 V) and a resistance network.
  • To prevent electrolytical corrosion, the coaxial cable braid is only capacitively coupled to the earth connection.
  • Installation is easily carried out by means of the two hot galvanized mast clamps. The antenna has very small weight and minimum wind surface, thereby requiring only a minimum of mast strength.
  • The glass fibre construction gives a stiff and self-supporting structure with extremely good resistance against the corrosive marine environment with UV-radiation, salt, exhaust gases and ice formation as primary factors.
  • RX 5000 is a maintenance-free and very reliable construction.
