Definitions

  • This invention relates to aerial systems and electrical power systems for use in connection therewith.
  • the invention relates to ar- 5 rangements wherein it is required to supply electrical power (e. g. direct current or alternating current at the usual power supply mains frequencies) to load devices which are so positioned that said devices or the power leads thereto are relatively close to an aerial system or systems required to have directional qualities.
  • electrical power e. g. direct current or alternating current at the usual power supply mains frequencies
  • load devices which are so positioned that said devices or the power leads thereto are relatively close to an aerial system or systems required to have directional qualities.
  • a common example of such an arrangement arises in connection with aerial systems employed at aerodromes since normally it is necessary to provide an illumination system c. g. a signalling light system for navigation purposes, at the head or heads of the mast or masts carrying the aerial system.
  • the present invention may very advantageously be employed in connection with the energization of navigation and similar lights required to be pro vided adjacent aerial systems erected in or near aerodromes.
  • the principal object of the present invention is to provide an economical and simple arrangement whereby electrical power supply of ordinary mains (i. e. comparatively low alternating current frequency or direct current) may be taken to loads such as lamps arranged adjacent aerial systems required to have directional qualities substantially without affecting those directional qualities.
  • ordinary mains i. e. comparatively low alternating current frequency or direct current
  • electrical power 45 supply to a load arranged adjacent an aerial system is effected either by utilizing a part of the aerial system itself or the lead thereto for the power supply and providing chokes for eliminating radio frequency from the power source and condensers for eliminating power from the transmitter and/or receiver associated with the aerial system or alternatively by arranging the power supply leads symmetrically with respect to the wires of the aerial system or part thereof.
  • the wires land 2, or 3 and 4, of each pair are connected together at the top of their mast through a navigation lamp i2 or B while the lower ends of said wires are connected through radio frequency chokes 5 and ii, or i and 8 and a switch M to the lighting mains LMQ
  • the individual wires I and 2, or 3 and t are also connected together as shown at points just above the chokes, the junction points being connected via blocking condensers 9 or It to a conductor l5 which is coupled at It to the transmitter and/or receiver (not shown) associated with the aerial system.
  • the conductor l5 constitutes one of the horizontal screened conductors described in said specifications while the wires of each pair of two vertical wires I and 2, or 3 and 4, serve in parallel as one of the aerials and in series as the mains circuit to the lamp.
  • the blocking condensers may be enclosed in a screening box which is formed as an extension of the screen H for the horizontal wire I 5 and this screening box may also house as much of the leads to the points above the chokes as is practicable.
  • each lamp l2 or I3 is energized through a twin cable H or l8 the twin wires of which are contained within an external metal braiding or covering H3 or 20.
  • the twin wires serve as the power energization circuit to the lamp [2 or l3 and the metal braiding is utilized as the aerial or part thereof, e. g. as one of the vertical aerials in a system in accordance with either of the prior specifications above referred to.
  • a copper tube is employed as the aerial or part thereof and the lighting cables are run inside this tube, while in yet another arrangement the aerial or part thereof is constituted by a cage of wires, e. g. four wires, within which the lighting leads are axially and symmetrically suspended.
  • an antenna system comprising two vertical aerials spaced apart from each other, each aerial comprising two vertical, parallel wires, a screened horizontal feeder coupled to high frequency apparatus extending between said two aerials, the two wires of each aerial being connected together at their lower ends through two condensers, and a connection including a blocking condenser between the junction point of said first two condensers and the horizontal feeder, whereby the wires of each aerial are in parallel relation with respect to the high frequency apparatus, a lamp across the upper ends of the wires of each aerial connecting said wires together, low frequency apparatus and a horizontal two-wire transmission line from said low frequency apparatus to the wires of each aerial, and a choke coil between the lower end of each wire of each aerial and said transmission line, whereby the high frequency currents from said high frequency apparatus are prevented from entering said transmission line and the directional qualities of said aerials are unaffected by said low frequency circuit.
