Diamond SWR Power Meter

Everything the does for you on HF, the Diamond Antenna SX400 Power Meters will do on VHF and UHF. SX400 meters measure forward/reflected power and SWR using a single sweep meter. Their compact size makes these meters useful for testing both base and mobile installations. Featuring switchable RMS or peak power, the illuminated meter (external power required) also displays antenna SWR, as needed. The small size of these meters will allow for installation in many vehicles, and the 140-525 MHz coverage suits numerous VHF/UHF base and mobile transceivers.
