These new MFJ Giant SWR / Watt meter series have large 3 ⅝" Cross-Needle SWR / Watt-meters that have a three-color scale for improved readability. 
 

• These wattmeters simultaneously display forward/reflected power and SWR all at a glance! They each have individual meter scales for each power range that increase reading accuracy.

• A True™ Active peak-reading circuit is included for SSB operation.

• LED backlighting provides smooth and even illumination for easy night viewing.

• Low bias Schottky diode detectors increase linearity from low power to high power readings.

• A true directional coupler for increased accuracy gives solid readings over the entire frequency range, HF to UHF.

• DC grounded antenna connectors prevent electrostatic build up.

• SWR less than 1.2:1. Meter accuracy is +/- 10% of full scale or better.

• Has lighted meter on/off switch.

• These wattmeters are extra sturdy with large rubber feet and a rugged metal and a designer-styled plastic injection molded front panel.

• Handsome black speckled finish and gray molded front panel aesthetically complements today’s modern transceivers.

• Quality SO-239 connectors.
