STATION PLACEMENT AND FIELD SURVEY 515'Determining the Population Served by an FM Station"*, BroadcastNews (October) 1946.Summary— The method of using Minor Civil Division Maps andPopulation Bulletins' in determining population within the practicalservice area of an FM station is discussed. This informationis required when applying for FM Construction Permits. Thevarious steps in the required procedure are clearly outlinedand explained.Decimal Classification:R630.ll.'A Non-Directional Antenna for Mobile Field Strength Measurementsin the FM Band"*, B. W. Robinst, Broadcast News (June) 1947.Summary— FCC "Standards" require the use of a non-directionalreceiving antenna when making field strength measurements ofFM Broadcast Stations. Such an antenna, capable of being usedwith the Standard Field Intensity Meter is described in thispaper. The antenna is of simple arrangement but must be tailormadeto fit conditions. Hence, it is not a regularly manufactureditem. The experimental work on and with this antenna is described,however, so that station engineers may adapt its principlesfor their own specific purposes. The paper includes antennaspecifications, mounting problems, and a number of representativepatterns obtained through its use.* Decimal Classification: R630.ll.% Engineering Products Department, RCA Victor Division, Camden,N.
