ANTENNAE OF OTHER TYPES ARE DESCRIBED Cage, Loop and Umbrella Forms Have Each Certain Advan tages and Special Uses. Borne of the newer feneration of radio araateura may here been led to think that the cafe antenna Is ui.»re efficient than other forms. One of the arguments advanced for their use lb that they have been adopted by the United States navy on all ships. There la a food reason for the adoption of tills type of antenna for the navy, hut It Is not because of the great efficient** of the cafe type. In fact, the only rea son the cafe type la used at all In the navy Is because of the fact that It would be difficult for an enem> shell to carry away the antenna with a single shot There seems to be a food deal of misinformation on the merits of the cage-type antenna They make it pretty appearance, It la true, but un fortunately In radio, pretty la aa pretty does, and It takes more than any artistic appearance to do the work. One of the so-called advantages of the cage la that high tension corona losses are reduced to a minimum. If the amateur la using undamped oscil lations, that Is, using a vacuum tube transmitter, he need not be concerned about corona losses. However, if a dumped or spark transmitter Is used, the cage antenna will be advisable. Also uniform current distribution la secured by the use of the cage an tenna. This Is not the case with the flat-top antenna, where the currents sre not equal, the outer carrying more current than the Inner wires. From the foregoing It may be said that the cage antenna Is to be preferred to the flat-top only because of the reduction of the high-voltage corona losses and because of the uniform current distil button. It has been shown that antennae have certain well defined directional char acteristics. The one having the moat clearly defined characteristics Is the loop antenna shown In Figure 9. In actual practice a very satiafac tory type of loop antenna for recep tlonal purposes consists of eight turns of No. 16 wire, spaced one-eighth, and wound on a frame 80 Inches square The fundamental wave length of this antenna Is approximately 180 meters Obviously loop antennae need not be square. They may be triangular, circular, or any closed shape, and their linear dimensions are not nec essarily fixed. Due to their small dimensions, the amount of energy picked up by them la also small, and therefore they should be used only with several stages of radio frequency amplification before the detector. See Figure 8, In which the loop Is shown with only a detector. In the hook-up, L Is the loop anten na. and forms the Inductance In the oscillating circuit. C Is the variable condenser connected across the loop terminals and la used to tune the loop !’«. the proper wave length. A loop antenna In this manner has extremely sharp directional character istics and iccelves signals only from stations In the plane of the loop. That la, the loop must be parallel to the direction of Travel of the wave sent out by the transmitter. Many good circuits have recently seen devised whereby loop antennae are used with success In eliminating •tstlc Interference. This elimination •» accomplished partly by the small linear dimensions of the loop and. paiil> by Us inheivm i. ■« lei i ■ One of the moat imp .-atlons of the loop am<-i.-> radio coinp.tsf |nr ship, airp i '• submarine.

This system is the mi* used by the numerous naval radl« compass stations along the sea coast The umbrella-type antenna, as Ulus trated In Figure 10. receives Its nam* front its general shape and slmllarlt; to an umbrella. Referring to the fig ure It will be seen that this type of antenna consists of a number of wire connected st the upper end of aver ileal mast and radiating from Ihl polnt In several direction*. The lead In la taken from the central point of the antenna system. In general, length of the radiating wires or “ribs*’ of the umbrella Is about two-thirds the total height of the must, ulthough this dimension is not fixed, and a different ratio may be employed with success. As can la seen In the Illustration. Insulators are placed about one-third of the way from the top of the "rib” wires, so that the actual antenna will be some distance above the ground. The over-all length of the "rib" wires. Including the guy wire. should he several times us long as the mast Is high. This guy wire can he fastened either to a sum 1 1 p<*-< or to a peg driven Into the ground. Due to the fact that the wires of the umbrella-type antenna cover a large area of ground, the capacity of the antenna Is very large. The total Inductance, however. Is only a llttie greater than that of the vertical por tlon of the antenna.
