By Capt. Robert Scofield Wood (D, F. C., M. C., Croix de Guerre ‘with four palma; formerly Command- wr 167th Squadron, Royal Air Force.) NOTES ON THE AERIAL. Practically five out of every ten questions asked by readers are con- cerning the aerial. And in the ma- Jority of cases wherb there is trouble encountered in the reception of mes- bages, news or music, the aerial is the faulty member of the unit. The fol- lowing 1s published for the guidance of all having trouble emanating from this source and for those just entering the realm of radioism. Much has been written concerning this vital section of the receiving set, and possibly too little emphasis has been laid on the importance of the aerial or antenna, as it is called. Remember that no matter how sensitive or near perfec- tion the instrument is without the gerial being fundamentally correct, one cannot expect to get the best re- sults from any receiving or transmit- ting unit. One noticeable instance of interfer. ence to the aerial was brought to the writer’s attention not long ago in the office of a very prominent member of the wireless fraternity. His aerial is just @ piece of bell wire dropped over the roof of the building, which is on lower Broadway, and pulled in the window about six stories below. The lead-in is brought to the instrument 1m the orthodox way. The aerial fouls against the building and several guy wires and stays for electric signs on the way down. The instrument in use is an exceptionally good one and costs $300 to assemble. It is in spite of this aerial rather than by its help that this instrument gives any results. Better reception can be had on a little crystal set with a proper aerial than on @ good vacuum tube set with an in- ferior one. There is no way of direct- ing one's attention to the importance of the aerial better than pointing out the extensive overhead apparatus of the largest wireless plant in the world, Radio Central. The Radio Corpora- tion of America has spent over a mil- lion dollars to erect this system of wires that are the ears as well as the tongue of the service. ‘The first to be discussed ts the re- ving aerial because it is in thie ype that the majority of fans are in- terested. This aerial to give the best recep- tion should be a single wire arrange. ment of about 120 feet long. It should be hung clear of surrounding objects by about twenty feet, and should for the best results be approximately par- allel, This is what is meant by the term, “long, low aerial for best re-| ception.” One need not try to hang an aerial on the moon to get good re-| ception. Just make sure that it is reasonably clear of the buildings in your immediate vicinity. This type of aerial can be made of any of the! following metals with equally goéd results, Stranded phosphor bronze is undeniably the best substance for aerials, and is about twice the price of stranded copper wire used for the same purpose. Tinned copper also makes good aerial wire. Aluminum wire can also be used for receptive purposes. It is very cheap, but is not as reliable as the other wires. The aluminum wire breaks very easily and corrodes at all junctions where ex- posed to the weather. All copper wire has a tendency to sag after it has been up a while, but this does not impair its receptive properties. More than one wire in a receiving nerial of the ordinary type will not increase the intensity of the signals but will increase the reception of in- terference. In this connection always remember that to swing your wires parallel to wires carrying heavy elec- tric charges such as car lines or any line electrically driven is inviting un- necessary interference, The way to avoid this trouble ts to swing it at right angles to the power lines. ‘An extensive system of towers for mounting the wires is not necessury. Any two objects such as a hjgh tree and the roof of the house or similar objects will db. In the city any apart- ment roof is high enough and there is usually plenty of room on the roof to swing a good aerial. A complete article on the construction of tie aerial can be found in Radio Column of Jan, 20. The transmitting aerial is one in which height can not be emphasized too greatly, Remember that in trans- mission it 1s the vertical section of the antenna that does the most work. ‘Vherefore, the longer this section the better the signal will be. Next in im- pertance is the physical location of the acrial. It is best to erect, wherever TO HELP RUSSIAN SCHOOL CHILDREN American Relief Administraton Gets Appeal for Books, Ink, Pencils and Other Supplies range the poles or supports for the aerial so that the lead-in when drawn vertically up with the aerial will be as near 100 feet in length as it 18 pos- sible to get it.
