The model C1277 broadband power/SWR meter by Werlatone is an inexpensive instrument for amateur use in the HF and VHF range.
The C1277 covers 27 to 450 MHz continuously and features dual power-range scales for 15 and 50 watts. A unique broadband coupler provides a useful bandwidth approximately eight times greater than previously available.
No plug-in units or separate indicators are required. Wattmeter accuracy is
±10% when used with a 50-ohm antenna system. Sensitivity for SWR measurements is less than 5 watts. I
