RF5 VHF ANALYST
The pocket-sized RF5 is designed to check and adjust antennas, feedlines, and RF networks. It includes a microprocessor, A/D converters, and a low-power "transmitter" with 4 digit frequency readout. The RF5 goes beyond the frequency range of the RF1 to cover all remaining ham bands to the 440 MHz band beyond, plus most frequencies in between. Frequency coverage is 35 to 75 MHz and 138 to 500+ Mhz continuously. This is in three bands of approximately 35-75, 138-290, and 275-500 MHz. It measures RF values of true impedance (0-600 ohms), SWR (1 to 6:1). (Available on special order for an extra $20 is continuous coverage of 70 to 500 MHz in 3 bands, but no coverage below 70 Mhz. For example, RF5's with this coverage are currently used by the FAA to adjust airport antennas.) As with all analysts, the RF5 has a standard UHF coax connector. The screw you see ...
