RF Antennas Have Internal Helical Element To Reduce Physical Height

With Part 15 compliant connectors that mate with a wide range of low-cost board and bulkhead connectors, RH Series 1/4-wave antennas use an internal helical element to greatly reduce physical height while reportedly maintaining outstanding performance. Designed for compact spaces, the antennas are ruggedly constructed to withstand punishing environments. Characteristic impedance is 50 ohms and VSWR is less than 1.9. Standard and custom frequencies range from 400 MHz to 1 GHz.
