Need Help with putting a Watt Meter in line

If you have say a 100w meter and a 500w amp can the amp be run after the meter once tuned ?
Radio to swr/ant matcher to amp to antenna selector ?
I have been told cb, amp, swr, ant switch ?... 351....

As long as you don't exceed the watt meters rating. 500 watts through a 100 watt meter is a recipe for disaster. If you are talking about placing it between the radio and the amp I would ask why.

if you do it that way the meter will be showing the power from the radio (not the amp) and the swr section won't even see the antenna , it will only see the impedance from the amp . and FWIU a swr meter can't be used to show or tune the input impedance of the amp . always , always , always only have coax between the swr meter and the antenna . you can put a antenna switch after a meter .... but i'd tune the antenna without it and then add the antenna switch . if re-tuning the antenna or troubleshooting changing swr , take switch out to be sure it hasn't developed a problem .
