  • Page 9: 1.0 Introduction

    Both input and output are well matched to 50 Ω and 377 Ω respectively. Comparisons of measured versus computed gain and antenna factors have been found to be within ±0.5dB. The Model 3160 Series antennas are considered to be the standard reference of measurements above 1 GHz, as is the resonant dipole for measurements below 1 GHz.

  • Page 10: Ets-Lindgren Product Information Bulletin

    Model 3160 Series, see Mounting Instructions on page 15. The Model 3160 Series may be used for either transmission or reception. The 50 ohm input impedance is well-matched for generating high electric fields with little power reflected back to the amplifier, reducing the chance of saturation. As a receiver, the antennas are matched to free space (377 ohms).

  • Page 11: 2.0 Maintenance

    • If the Model 3160 Series is used outdoors, the antennas should be checked for water accumulations. Water has a high dielectric constant and can alter performance.

    Connect the output connector of the antenna to the input of the receiving system using a low VSWR, low loss coaxial cable. The Model 3160 Series Pyramidal Horn Antennas are designed for receiving systems having 50 Ω input impedance. Other values of receiving system input impedance will require correction for the difference in impedance mismatch.

    The losses of the coaxial cable, A , should be included in the computations. In this case, the previous equation becomes: RF Voltage, dB(µV) + Cable Loss, dB + Antenna Factor, DB(m ) = Field Strength, dB(µV/m) + AF Conversion Formulas Following are some useful conversion formulas, including how the constants are obtained: QUATION...
