Definitions

  • My invention relates to radio antennae and more particularly to antennae of the doublet type.
  • a further object of my invention is to provide such an antenna which is free from breakable insulators, such as those of glass, and which at the same time avoids the necessarily cumbersome connections to such insulators.
  • Fig. l diagrammatically illustrates an antenna embodying one form of my invention.
  • Fig. 2 is a diagrammatical view of a portion of an antenna embodying a modified form of my invention.
  • Figs. 3 and 4 are cross sectional views of two of the insulators used in conjunction with the antenna shown in Fig. 1.
  • Figs. 5 and 6 are cross sectional views of two of the insulators used in conjunction with the antenna shown in Fig. 2.
  • FIG. 1 of the drawing I have illustrated therein an antenna constructed in accordance with my invention, and which comprises oppositely extending conductors I and 2. These conductors have their inner ends secured together but insulated from each other by insulator 3 and their outer ends supported from suspension members 4 and 5 through the strain insulators 6 and I, respectively. Intermediate points on the two conductors are mechanically and nonconductively connected together by a suitable supporting member 8 which is of such a length as to retain conductors I and 2 in the desired form, which may be that of the V-doublet shown in the drawing. The ends of the supporting member 8 are connected to the conductors I and 2 through insulators 9 and I0, respectively. Transmission line II and I2 may be soldered or otherwise connected to conductors I and 2 either within the insulator 3 or at a point exterior thereof.
  • Fig. 3 illustrates the manner in which the outer end of conductor I is connected to the suspension member 4 through the insulator 6.
  • the outer end of conductor I is bent over a small ring I3 of nonconducting material.
  • the suspension member 4 is similarly bent over the opposite side of ring I3. Rubber is then molded about the joint to form insulator 6. In order that the rubber will withstand ageing in the sun and weather, the mix may have some suitable substance added for this purpose. It will be apparent that the purpose of ring I3 is to provide a means for relieving the rubber of large tensional stresses.
  • Insulator I is formed in a similar manner about the outer end of conductor 2 and the end of the suspension member 5.
  • Insulators 9 and III are constructed in a manner similar to that of insulators 6 and I with the exception that the conductor does not terminate within the insulator. Referring to Fig. 4, it will be seen that conductor I passes through the ring l4 and is bent back on itself for a distance sufficient to bring the conductor outside of the insulator.
  • the supporting member Bis connected to the ring M in a manner similar to that of suspension member 4 on ring l3. Rubber is then molded about the joint to form insulator 9. It will be noted that by bending conductor l in the manner described the same type of mold may be used for insulator 9 as is used for insulator 6. Insulator I is formed in a manner similar to insulator 9.
  • Insulator 3 may be formed from the same type of mold as that used for either insulator 6 or insulator 9 by passing conductors l and 2 through the ring of insulating material in the manner similar to the passage of conductor I through insulator 9 as described above.
  • the antenna described comprises a single integral unit which may be readily assembled at the factory.
  • the antenna unit may be folded into a small compact kit which may be easily shipped and readily stored.
  • the unskilled purchaser may install the antenna for operation With assurance of obtaining satisfactory results therefrom when used in conjunction with an all-wave radio receiver.
  • Fig. 2 of the drawing illustrates a modified form of my invention wherein molds of different shapes are used to provide insulators of a more pleasing appearance.
  • I have substituted insulators l5 and I6 for the insulators 9 and ID of Fig. l.
  • Insulators l5 and 16 have a form which permit conductors l and 2 to pass directly therethrough.
  • This will be readily understood by reference to Fig. 5 where I have shown a cross section of insulator l5.
  • Conductor I enters the insulator [5 through end surface ll, passes through the ring l8 of nonconducting material and then passes out of the insulator through end surface 19.
  • Supporting member 8 is connected to ring l8 in the manner similar to that described in connection with Fig. 1.
  • Insulator I6 is formed in the manner similar to that of insulator [5.
  • an insulator 20 may be employed, this insulator having a generally delta shape. Since the stresses are relatively small in the insulator which is used to connect the inner ends of conductors l and 2, I have omitted the ring of nonconducting material which serves to relieve the large tensional stresses in the other insulators. Instead, I simply loop each conductor once as is indicated at 2
  • an antenna doublet comprising a pair of oppositely extending conductors, means including a supporting member for mechanically connecting said conductors together at points intermediate the ends thereof, insulating means molded to said conductors at said intermediate points and to the ends of said supporting member for connecting the ends of said supporting member to said conductor, and a. second insulating means molded to the inner end of said pair of conductors, the length of said supporting member between said first insulating means relative to the length of said conductors between said first and second insulating means being such that when said antenna doublet is suspended from the outer ends of said conductors it falls into substantially an inverted delta formation, said conductors extending continuously through said insulators to form the opposite sides of the doublet.
  • An antenna comprising a pair of oppositely extending conductors, a transmission line connected to the adjacent ends of said conductors and a single substantially delta-shaped insulator molded about said connections, each of said conductors having a loop therein within said insulator.
