- Page 3 WARRANTY This Model RVR-30M Vertical Antenna is warranted for a period of 12 months (USA only) from date of shipment against defective materials and workmanship. This warranty is limited to the repair of or replacement of defective parts and is void if unauthorized repair or modification is attempted.
- Page 4 EMC-30 Interference Analyzer, it can be used with any equivalent 50-ohm receiver/analyzer being designed and calibrated for use in a 50-ohm system. The Model RVR-30M is designed for use in conjunction with the Model GPA-30 Counterpoise, Model TRI-136 Tripod, and Model CAC-30 Coaxial Cable.
- Page 5 50-ohm instrument. 4.0 Theory Of Operation The Model RVR-30M Vertical Antenna, is basically a 1-meter (41-inch) rod. As is the case with any rod antenna, optimum transfer of an intercepted signal to the receiver using 50- ohm cable requires that the rod be fed to an impedance transformation network. Since it is...
- Page 6 6.0 Electric Field Measurements 6.1 Narrowband Radiated Signals With the Model RVR-30M Remote Vertical Antenna, connected to the 50-ohm receiver, as described above, tune the receiver to the frequency of interest. Read the two-terminal voltage indicated by the receiver for the particular signal of interest, following the calibration and operating procedures in the instruction manual of the receiver.
