|Having used SWR bridges from Bird to Lafayette Radio over the years, I feel that this model comes closer to the level of the Lafayette.|
There is nothing wrong with this product,it is just dinky. I used it once or twice to adjust a mobile HF antenna. The purpose was to get the SWR under 2:1, which was not a problem using this bridge.
I would not want to use this meter in a setup that required me to tune a matchbox for minimum SWR, the meter and controls are too small for my tastes.
I don't see how this SWR meter could be used as a wattmeter given the non-specific impedances (reactive?) that it might have to work with. MFJ says that one of the calibration markings is not accurate (see photo) - procede with a grain of salt on this item.
The bridge has enough sensitivity to work well with QRP or CB radios, too.
Not bad for the money for casual or set up use.
