6.0 Application
The Model 3110C Biconical Antenna is ideally suited for swept site attenuation
measurements per ANSI and FCC specifications. The Model 3110C can be used
for horizontal and as vertical site attenuation measurements. A 20 dB
pre-amplifier is recommended in line with the receive antenna to minimize the
required transmitted power and to reduce the possibility of saturation of the
transmitting antenna. The maximum continuous input power to the Model 3110C
is 250 mW.
When the Model 3110C is used vertically, the same element orientation need not
be maintained from measurement to measurement. The Model 3110C exhibits
excellent symmetrical performance, and test repeatability is assured by the balun
design.
Each antenna is calibrated during manufacturing. The results of the calibration
are tabulated as gain and antenna factor vs. frequency for use in Specification
Compliance Testing. Typical data for the Model 3110C is provided in the next
section.
