Low Power Narrowband FM
Circularly Polarized Antenna
This antenna is built of stainless steel and is designed for circular polarized transmission with medium and low power installations. It is factory tuned to the requested frequency. However, it can be re-tuned in the field, with proper test equipment, thanks to the adjustable sliding stubs. The low cost of this antenna makes it a good choice even for systems composed of many elements.
