APPENDIX IIFM STATION PLACEMENT AND FIELDSURVEY TECHNIQUESThe ever-increasing number of FM stations now in the planning stagehas focused attention on the difficult problems of station placement and fieldsurvey work. It is considered both appropriate and timely to include herewitha bibilography of material relating to these problems with the assurancethat this guide will assist to some degree in the solution of theseproblems."Selecting a Site for an FM Station"*, John P. TaylorJ, BroadcastNews (January) 1945.Summary— This paper treats with the problem of choosing anappropriate station location from a very practical point of view.First, the factors to be considered are discussed in some detailincluding technical requirements, importance of central location,height, and other practical considerations.
