PART I, | Brom the flood of mail that te pouring to the office of this department asking on proper’ installation and lve devices to cope with the conditions askociated with the summer months, it is evident that ¢fnany fans who, joined the order of ‘‘ra- » Mio hams” during, the winter months filsregarded the precaution of installing Nghtning protective devices when first “putting ‘in thelr outfits. Fortunately there ts no use for lightning arresters A phd ewitches during the late ‘fall, win- fter and spring, as electric storms are cally unknown during this period, 4 enthusiastic “radiors,” seeing no | Ammmediate call for the outlay for the | prescribed instruments of protection, ‘have passed them up until now, when f entering the ueason of more or leas risk ‘from electric storms: they all seem to \vaimultaneously look along their lead-in jewires and discover the absence of the ji meceasary , equipment, _ From time to time in these columns we have expounded the necessity of “taking every precaution possible to * guard against fire from lightning by th ) Mnatallation of the proper protective struments. The following article being published for the protection of “radio ‘fans, as it 1s impossible to devote the epace required to answer separately each individual's questions. It was pre- pared by G. K. Taompeson, radio engi- eer, and Superintendent of the Ameri- \ ean Radio Research Laboratories: If’ your radio set is not already in- |p stalled. according to regulations, you should attend to the matter at ohce. ‘hé regulations are in force the year und and should be complied with as .mearly as possible, That they are dis- Tegarded is « well known fact, but this megligertce means that after the first thunder clap thousands of people will atorm dealers for protective devices ‘and their meager supplies will be ex- jwusted in short order. One of the first questions which comes into the mind of the embryo wadio \user concerns lightning. ‘Will my antenna attract lightning and cause house to be struck?” he asks. To jo" general Boley wireless and light- Ing stem to be twin brothers; prob- “ably ‘because she manifestations of Fpoth vare ‘not understood. Holsting a radio santenna over your property does not ~endanger. your sveiing, your instru- ments or your family, If a few simple precautions are observed. You have Thever felt apprehenstve about the tele- sphone wire running from the pole on ‘the sidewalk to your house. You, do one regard the bell wire circuit run- ning from the front door to the kitchen ints lightning conductor, nor have you nervous over the presence of a wife clothesline in your back yard, the| P. M. “tin roof over your head or the metal gutters or leader pipes. All these com: moon and familiar mete) surfaces and and harmless, Take another cup of sas~ oline and dump it Into the gas tank of the family flivver, crank up, and drive thirty miles an hour head-on into a con- crete wall. The effect is startling. Even Henry himself could not put together the remains and make them rattle once more —yet the energy involved was no more than that necessary to melt the \ceaaped candle, The essential difference the fact that in the first case th fe ‘waa released gradually and in the second case the energy was released instananc- ously. A bolt of lightning represents an electrical collision, This accounts for its many, strange antics, such as stripping the doles from shoes of persons struck, gmashing crockery or ripping off wall paper. ‘The average lightning bolt never plays fageording to Hoyle, and if it does ever strike your antenna it will probably not follow the direct low resistance path to the ground which you have carefully provided but, instead, may jump to the chicken coop, causing feathers to fly, or wreck the gas stove or refrigerator. ‘The lightning, if it ever Strikes, will be blissfully oblivious to the fact that you ever had @ radio set or antenna or ever thought df having one, You may have a fine nickel plated bumper on the front of your automobile, but if you collided with @ locomotive going sixty miles an hour, {t would be ajficult to find the remains of the car, let alone the nickel plated bumper. Part two of this artiole wilt appear in this column to-morrow, CITY COLLEGE RADIO CLUB NOTES. At the election of officers for next term, Richard Carlisle, formerly chief operator, was elected President of t club; Lyman Barry was re-elected Vi President and David Weinbloom Gecre- tary-Treasurer. The plans for the coming semester include the addition of two uteps of ra- dio-frequency amplification to the re- celving using the super-hetrodine circuit; the substitution of @ 100-watt tube transmitting set for the present 20-watt one; a, radio course for about 100 students, consisting of weekly lec- tures and code practice In a/room es- pecially obtained for that pul and @ weekly radio concert to be given to the 2,300 students of the college.

This at- ‘mospherfe electricity is known as static, and with the coming of warm weather it-ds present in large quantities. The Anfense heat of the summer sun evap- ton the moisture from the surface of rth and water from ponds, lakes Kory rivers very rapidly. This evapo- ‘fated ‘moisture or “vapor, becoming heated; rises to the upper atmosphere, ‘and upon reaching the higher levels where the temperature 1s lower, the water vapor condenses, into minute dfops of moisture and forms clouds. Each molsture particle becomes charged { with a very small amount of electricity. ‘As the molsture particles in the upper alr’ become more dense the particles crowd together and combine with one another. This combination increases the electrical charge on each particle until finally a thunder cloud {s formed watch 4s highly charged with electricity. t Is a known fact that when thunder sor are in formation electrical dis- eeharges occur within the cloud. These discharges are popularly known a8 sheet lightning. Every time such a discharge takes place, radio waves are ated and, impinging upon an an- cause @ sharp crash or crackle earphones !f you happen to be listening in. “"« thunder cloud must be regarded as “a huge bubble containing electricity. Discharges are constantly taking place within the bubble and increasing in Wize. When a certain critical point 1s reached the bubble burts, the pant up _ electricity discharges in one swoop to and we hear a mighty thunder- If this Mghtning bolt strikes within a mile of your antenna consid- rerable current will be induced in your aerial system. This induced current will pass harmlessly to the ground, and you will be unconscious of its presence At you have taken the proper precau- Hons. Let us consider the great bubble once more. If we prick tiny holes in this bubble while it ts in process of forma- fon, the sup electricity will gradu- nity discha It we prick enough hol dn the bubble the electric charge m: leak away so fast that the quantity of electricity within may never reach the point where the bubble will burst. The function of the common ghtning rod and the properly grounded or protected antenna is to prick holes in the great electric bubble in the sky and convey its charge silently to the ground. For this purpose the average radio antenna is ex- ectly as effective as the lightning rod. “What will happen if a lightning bolt actually strikes my antenna?’ is a fa- milar question. Let us consider the n fure of a lightning bolt. The heavy thunderclap which attends its appear- ives the impression of tremendous It 1s true the lightning {# de- but as @ matter of fact its dark deceives one of its might. The lightning bolt cor out ‘auch energy as represented In a pint of gasoline. ‘The only difference is that the energy of lighting 1s. exerted instan- taneously.
