Page 7: Introduction
1.0 Introduction The ETS-Lindgren Model 3140B BiConiLog is a high-field antenna in the bow tie/log periodic family, providing the highest field-to-power ratio at low frequencies of any of the BiConiLog antennas. The Model 3140B is designed specifically to generate the field... - Page 8 The unique feature of the Model 3140B is the T bow tie elements. A T bow tie increases the equivalent dipole electrical length, thereby decreasing resonant frequency and increasing efficiency in the 20 MHz to 60 MHz range. Similarly, a regular bow tie has a lower resonant frequency than an equal length single-wire dipole.

Model 3140B before dropping vertically. Both horizontal and vertical polarizations are easily accomplished when the Model 3140B is mounted on an ETS-Lindgren tower. The Model 7-TR Tripod Positioner is designed specifically for T bow tie BiConiLog antennas for easy changes to polarization, and with the air polarization option can provide automated polarization using a Model 2090 Multi-Device Controller. - Page 32 3.24 (1.8 ). Actual transmitted field strength should be verified using an ETS-Lindgren Model HI-6005 Field Probe, or equivalent. The forward power data graphs on page 39 and page 40 show power requirements for the lower frequencies at three meters based on measurements using a field probe on an Open Area Test Site (OATS) over both conducting ground and a (2.4m)
