A REN'T you finding, Mr. Broadcaster, that your prospecjfl. tive advertisers are becoming more inquisitive regarding the effectiveness of your transmission . . . less satisfied to i accept that rather doubtful "coverage" which you based on la circle of arbitrary radius? Wouldn't you like to be able to j make a field survey of your station pattern ... to have available •an instrument with which you could measure your signal intensity anywhere at your convenience? Engineers of the RCA Victor Company, Inc., thought so, and so they spent over a year developing a field intensity meter particularly fitted for your needs. A meter which is a vastly different instrument
from former designs which required a truck for transportation. Mounted in a single small case, this meter can be easily carried about by one man and quickly set up anywhere on its convenient tripod mounting. With it you can accurately measure intensities ranging from the weakest signals which can be identified in a superheterodyne receiver to the blanketing signals in the proximity of a 50 KW station. Moreover, Mr. Broadcaster, you can measure the intensity of your second and third harmonics as well as your fundamental. Bulletin No. 13 has more to say of this Type TMV-21 Meter. If you haven't received your copy, ask for ic today.
