I have no manual, this is what the box says.
Measures VSWR from 1:1 to 20:1 3% accuracy, measures power in two ranges: 0-10 watts, 0-100 watts - 10% accuracy, measures modulation from 0-100% 10% accuracy and measures filed strength 3.5 -150 MHZ.
According to the box it measures field strength from 3.5-150mhz.
It it not specific about VSWR (or power).
Anyone familiar with the Philmore, I like to roll my own when it comes to antennas for VHF, either cut down CB or extend cellular mag antennas. I am used to using alot more hi-tech equipment at work to test and tune but I like something for the house.
Should I trust the Philmore on VHF?
