BURIED AERIALS

MAY OVERCOME STATIC A rather interesting experiment fostered by one of tjie principal radio magazines may result in overcoming the static trouble. It is not believed that many persons with radio sets realise it is perfectly feasible and practical to bury an aerial. The main purpose of such procedure would be tp bury static likewise in these underground aerials. The experiment being made' by persons in the United States will afford valuable information that will cover soil, climate, and all other factors which may have a bearing on the subject. There are hundreds of variations that may be made in the installation of an underground aerial, and Urn results of these experiments will throw considerable light on the subject. One experimenter had the following to say: "The volume is splendid. I obtain clear, distinct, and resonant reception, entirely free from gaseous atmospheric conditions such as usually received through an ordinary aerial." In this particular set, two lengths of No. 14 seven-strand insulated copper wire, each 50rt long, were used, and coiled about' 4ft apart, and approximately 4ft uncle/ground. The wires were laid in circular form, and spaced each turn one above the other with half-inch separations. The spacing of -the turns was accomplished by lilling iii with soil, as each layer was placed. The ground was thoroughly soaked afterwards to obtain a good moisture contact. It is impossible for the average listener-in to lay a 50ft underground aerial in his garden, but as mentioned above, through the experiments being carried out, it may be found that some other smaller form of underground aerial will suffice. However, anyone with plenty of space and an experimental turn of mind could do worse than try out some types of buried aerials. In all cases heavy insulated wire is used, and the depth that tho wire is buried varies from one to oft.
