Set of 4 Electro-Metrics Antennas: RVR-25(2), LPA-25, TDA-25, TDS-25-2, TRI-25 (Tripod) Condition: Used. Appear to be in good condition. See Photos. RVR 25 Receivers are untested so they are in unknown condition. Electro-Metrics RVR-25 10 KHz to 30 MHz Receiver with monopole antenna and power cable. Also an additional RVR 25 Receiver. Both are in unknown working condition. Electro-Metrics RVR-25 Switchable E Field Rod or Monopole Antenna Base - 10 kHz to 30 MHz for EMI, EMC, and TEMPEST work. Originally configured for MIL-STD testing. The RVR-25 remote/manual Switchable E Field Rod or Monopole Antenna transforms E-fields by switched passive matching circuits from 9 kHz-30 MHz and has been designed for use with the Electro-Metrics EMC-25 and 30 but can be used with other 50 input systems. It covers the same octave ranges as the ten matching bands of the EMC30 Receiver and similar pieces of test equipment. The matching network switches automatically via the ACC-25A/30 control cable connects to the Rx. The use of tuned matching transformers increases the sensitivity of the antenna whilst reducing the risk of overload across the band. It is tuned by means of a controller box (not included) which selects one of 10 different bands. The schematic for the controller box is included. The bands are: 10-35 KHz 35-70 KHz 70-150 kHz 150-250 kHz 250-500 kHz 500-1.1 MHz 1.1-2.4 MHz 2.4-5.5 MHz 5.5-12.4 MHz 12.4-30 MHz Electro-Metrics LPA-25 Log Periodic Antenna. The label has been damaged. Please see the pictures for the label picture. It appears to be the LPA-25 from everything that I can determine. Similar to: EM-6950 (LPA-30 Old Model Number) LOG PERIODIC ANTENNA Features • Wide frequency coverage • High sensitivity • Flat frequency response • Compatible with many measurement instruments Description The Electro-Metrics EM-6950 Log Periodic Antenna was designed to operate over the 200 MHz to 1 GHz frequency range to meet VDE/FCC, military, and other EMI specifications. The broadband frequency capacity of the EM-6950 eliminates the need for band switching, element extension or external tuning when used for EMI ambient surveys or spectrum signature measurements. Applications The EM-6950 is capable of operating either as a transmitting or as a receiving antenna over the frequency range of 200 MHz to 1 GHz. Its linearly polarized design permits separate measurement of horizontal and vertical electric field components over its established range. All-Aluminum construction makes it easily portable and suitable for use in applications where space is limited. The EM-6950 Log Periodic Antenna is fully calibrated and used primarily for radiated emission and susceptibility specification testing.
