A NOVEL AERIAL SYSTEM

PERMITS RAPID CHANGE- | OVER DESCRIPTION of a novel aerial system, which has been called the "fan aerial," is sent in by Messrs Gyde and Barringer, of Hawera, and as it will probably interest many. experimenters and others, particulars are here reproduced, It is stated that very great differences are noticeable in reception when ‘the different positions are used on a given station. The letter states that’ "sometimes, say, 2YA works beautifully on the "'T" tapping, then another time it works better on a "L" or full "LL," and so on with other stations. The letter also claims that this nerial with the "fan" earth is ideal. Presumably the "fan" earth, is several earths joined radially at equal distances. It will scarcely be necessary to adhere to measurements, as the aerial

will be erected to suit available space. The diagram shows the aerial divided into four equal parts with four separate lead-in wires connected respectively at one end, and at the centre end, and at the centre and quarter and three-quarter positions. These are all led, insulated in proper manner, to 4 contacts of a switch, the arm of which is connected to the aerial terminal of the set. This gives a means of rapid}ly changing ver. from one style of

aerial to the other, and shouid provide some interesting facts for experimenters. The aerial in question is erected on 65-foot iron poles above a building, giving 40 feet clear above the roof, the lend-ins being breught to insulators and throvgeh a ventileter in the roof, eee eee Keech. © Sabha cel bee SIRE CEPRTOPAOPOIg ie Ore
