Seme beginners have ro-firli'tiil ro-firli'tiil spaces for aerials anil they tlilnk t tmt by nimiluK' Hie aerial In the form of n square h!1 around lie eil;e of the 1,,,-V wl" t;''t l'i't,,r results. Others ereot three polos on the roof Hid run single wire In the form of a trlnnfcle. Tills Is a waste of time ami wire. Kun It straight nwny nml not over 100 feet lone. Ivouionihor tlmt If it Is t,w hlh It will pick ui' more stntle. mat If It la too low. the signals will not he ns ood on Ions distance. A happy nieilluni must le hit somewhere In between. The load-In wire shonhl he taken from one of the ends nml not from the mkiille. If the latter way of taking off the aerial Is used the etTeotual length of the aerial will ho Just about cut In half. In other words, use an Inverted In-verted I. aerial and not a T aerial. If It Is not possible to ereot the aerial all In one length and In the same direction. It Is permissible to make k two or three-wire Berlal. However. It must be remembered that two wires I each rm feet In length nro nut Mm miiiio us n .single wire. 100 foot buig. There may bo HHI feet of who In the aerial, but the effective length will not be for the full 10O font. lie sure to Insulate Mm aerial from all surrounding objects. If th lead-In wire conies Into contact wits any of the surrounding objects there will be a decided tendency for tho current to leak off, and for the best results, e-peeliiliy e-peeliiliy on 1X signals, advantage must b taken of every little thing. The ground connection In fully as Important as the aerial, as It forum a part of the open circuit. The beat ground connection Is to the cold water pipe, as this Is the Kluutest and moat direct lend to the earth. The hot water wa-ter pipes anil the radiator system will do If necessary, but there are many more .bints In a' system of thla kind, and ax these pipe Joints are made up with white or red lead there w'.ll be a high resistance, which Is to bo avoided. Scrape tho cold water pipe until It shows a shiny tlnlsb and then either use one of tho ground clumps that may be purchased, or, better yet, take about ten turns of the ground wire around this pipe and solder them In place. If the ground clamp Is used, this also should be soldered to the pipe. Solder all connections In both the aerial aud the ground for the best results. |
