DESCRIPTION AND USE OF THE
EMCO MODEL 3108 HIGH POWER BICONICAL ANTENNA
General Description
The EMCO Model 3108 High Power Biconical Antenna is designed to operate over
the 30 to 300 MHz frequency range for measurements in accordance with present
and proposed DoD and Military EMI specifications. Its ability to handle large power
levels over a broadband make the 3108 excellent for use in Radiated Susceptibility
as well as Radiated Emission testing.
The lightweight breakdown construction of the Model 3108 makes for ease of
storage and portability. The biconical elements are made from tack welded
aluminum rods. The 4 to 1 balun network is fabricated from TFE thermoplastics
and silver plated brass and aluminum.
The Model 3108 is manufactured in accordance with ECOM drawings
ES-DL-176433 and ES-F-201286. Each antenna is individually calibrated during
manufacturing. The Gain and Antenna Factors for the individual antenna are
tabulated and included in this manual for use in Specification Compliance Testing.
Refer to Table 1 for Typical Antenna Factor and Gain.
Refer to Figure 1 for Typical VSWR vs Frequency.
Refer to Figure 2 and 3 for Typical Antenna Radiation Pattern.
Specifications
Frequency Range: 30 to 300 MHz
Impedance: Matched to 50 Ohms
Connector: Type N
Power Input Capability: 300 Watts Continuous Power
500 Watts Short Term Peak Power
Assembled Dimensions:
Length: 51.8 inches (131.6 cm)
Diameter: 20.5 inches (52 cm)
Weight: 6 lb (2.7 kg)
NOTE: EMCO recommends using a 6 db pad attached to the end of the
antenna, otherwise high VSWR may occur.
