The Sharman AV-40 is a 144 MHz to 470 MHz VSWR and power meter with a 15W/150W power switch. The AV-40 only works on 50 Ohm impedance which measures forward and reflected power and VSWR with a sensitivity of 3W for full-scale deflection.
The MFJ-828 digital SWR/Wattmeter/Frequency Countermeasures up to 1500 watts. It has three high-resolution ranges with accuracy in each range from 1.8 to 54 MHz. True peak or average forward and reflected watts, SWR and frequency can be simultaneously displayed.
Similar to MFJ-864 but for 1.8-60 MHz only. The push button selects 30/300 watts forward, and 6/60 watts reflected. Compact 5 3/4 x 2 1/2 x 2 1/4 inches.
