RADIOANTENNA.
Application filed September 16,` 1926. Serial No.. 135,836,
My invention relates to improvements in radio antennae for use in connection vwith `radio receiving apparatus and the object of `my invention is to provide a radio antenna that may be suspended vertically from the side of a building or froml `any suitable support thus making it possible to dispense with the usual overhead antenna wires and they unsightly posts and supports for t-he same and saving a great deal of time, laborand ex.- pen-se in installation,
Another object is to provide an antenna that is extremely sensitive, highly selective and nondirectional. f
A further object is to provide an antenna. that has'aV condenser incorporated into its construction. l
A stillA further object is toV provide a radio antenna in the natu-re of a vertically arranged copper pipe.
A more specific object is to provide efficient bracket means for suspending; said copper pipe and supporting the same against swinging movement.
Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawT ings- In the drawings Figure 1, is aview in side elevation of a radio antenna constructed in accordance with my invention as the same may appear when set up and ready for operation. l
Fig. 2 is a longitudinal sectional view of an antenna pipe having a condenser provided in its lower end.
Referring to the drawings, throughout which like reference numerals designate like parts, 5 designates a bracket of strong and substantial construction and ornamental appearance that is adapted to be secured as by screws 6 to a support 7, yas to the side of a building and that is provided at its outer end with a hook 8, arranged to be connected by a link 9 with an insulator 10, which is rigidly secured within the top end of a pipe 11 of copper or like metal. The insulator 10 is preferably sealed within the top end of the pipe 11 so as to exclude all forms of moisture.
Another insulator 12 is rigidly secured toA thepipe 11 toward the lower end and projects at right angles from said pipe. A rod 13 hereinafter termed a wind arm has one r end secured by a bolt 14 to thebottom portion of the bracket 5 and is provided on the other end with a hook portion 15 that is bentat right angles and is adapted to pro- ]ect into a suitable hole 16 in the end of the insulator 12. The bolt 14 extends through f a curved portion of the bracket 5 and is conpull. on the pipe 11 keeping said pipe under a. slight tension and. preventing rattling or noise between the insulators and the partsl connected therewith. The wind arm 13 further prevents substantia'lly all swinging movement of the pipe 11.
Concealed within the lower end of the pipe 11 isa condenser 17 having one ter*- minal' connected with the pipe through the cross rivet 418 and the other terminal connected with a binding post 20 that projects outwardly through a disc 21 of insulating materialthat is sealed within the bottom of the pipe. Another binding post 22 is connected directly with the side of the pipe. The lead in from'k the antenna to the. receiving instrumentV will. preferably be composed of two wires 23 and 24- one wire boing connected to the terminal post 2O and the other wirey being connected to the binding; post 22. l One of these.v wires only wil-lf be connected with the instrument at any one time so that the4 instrument will either be connected directly with the antennapipe `11 or willbeconnected with said pipe through the condenser. The same results may be obtained by the use of a single lead in wire which may be selectively connected with' either the binding post 20 or 22 this latter method is less convenient and is therefore less desirable.
In practice I find that excellent results with this antenna are secured when I use a one and one-quarter inch antenna pipe two and onehalf feet long and a certified condenser of .0001 microfarads capacity. This condenser may be of the mica and plate type.
After all of the parts in connection with the antennaV tube 11 are assembled said tube and assembled parts are thoroughly treated as with parafline and shellac to render the' tube absolutely moisture proof.
This antenna is non-directional due to the fact that it is formed of a cylinder of metal suspended vertically. It is very sensitive .in picking up electromagnetic waves from dis* tant transmitting stations and does not need to be elevated to any great height but may be suspended from the wall of a building thereby making it possible to dispense with unsightly overhead antennae that are difficult and dangerous to install and handler. especially when they are in close proximity to power transmission lines andv also greatly reducing the danger from lightning. It 1s Vfurther at right angles to most of the eddy currents arising from transformers power wires and the like.
' This antenna is highly selective when used wit-hout the condenser 17, but the selectivity is considerably increased when the connection to the antenna pipe is made through said condenser. l
I ind that much better results are obtainedV by the use of a copper pipe with walls of substantial thickness than are obtainedby the use of a thin walled tube or asolid barl of V copper.
The entire assembly is neat and symmetrical and is an ornament to a building when installed thereon.
The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely il lustrative and that such Vchanges in the device maybe resorted to as are within the scope and spirit of the following claims.
I claim:
1. A. radio receiving antenna embodying a piece of insulated copper pipe having relatively heavy wallsV and supported in insulated relation in a vertical position, a condenser disposed within the lower end of said pipe means in said pipe above said condenser for supporting the condenser and electrically connecting one terminal of the same to'said pipe, an insulator member forming a closure for the bottom end of said pipe and having a terminal post extending therethrough for connecting the otherk terminal of said condenser with a receiving instrument and another binding post connected directly with the bottom end of said pipe. i y
2. In a radio receiving antenna, a right angledA bracket arranged to be secured to an upright support, a radio antenna pipe, an insulator in the upper end of said pipe arranged to be connected with said bracket to suspend .said ypipe vertically, anotherv insulator secured to the lower end of said pipe and extending at right angles therefrom and a wind arm connecting said last namedy insulator with the lower portion of said bracket.
3., In a radio receiving antenna, a right angled bracket, an antenna pipe suspended from Vsaid bracket in insulated relation therefrom, a rigid insulator projectingat right angles from the lower end of said antenna pipe and a wind arm of resilient metal connected with said insulator andsecured tothe lower end of said bracket and arranged to exert a downward force on said insulator and prevent swinging ofsaid pipe.
4. In a radio receiving antenna, a right angled bracket arranged to be secured to a vertical support and having a hook portion on its outer end, an antenna pipe having an insulator sealed in its upper end, means connecting said vinsulator with said hook for` suspending said pipe, another 'insulator rigidly secured to the' lower end of said pipe and extending sidewise therefrom and hav ing a transverse hole in its outer end, and a resilient wind arm rigidly secured tothe lower end of said bracket and having a downturned outer end arranged to engageV within the hole in said insulator, said wind arm being adapted to exert a downward pressure on said insulator.
