[Antennas] SWR Meter

[George, W5YR]

Generally no, Tom. Most meters are frequency sensitive and power sensitive.
Usually, a meter designed for HF will work well up to 10 meters or possibly
even 6 meters, but a VHF or UHF version is usually required for 2 meters
and up. Meters for very low power levels are different from those designed
for very high power levels.

The Bird 43 wattmeter uses plug-in elements designed for specific frequency
and power ranges. It is among the very best of its kind in terms of
accuracy and utility over a wide range of frequencies and power levels.

Now, all the above is true is you want to determine actual SWR on a line or
measure actual forward and reverse power levels. On the other hand, if all
you are trying to do is make adjustments to minimize reflected power, then
any meter that is sensitive enough to move the meter(s) can be used. But
don't count on the calibration unless it is being used within its design
specs.
