Sorry I did not realize just how much of a newbie to radio you were. First off as I was trained, you do not check antenna tuning with a linear in the circuit. If an antenna is properly tuned at 4 watts it will be properly tuned at 4000 watts. Components inside of linears may pull the tuning off a bit. The problem with linears is that they amplify every thing including harmonics. The harmonics will show up as higher swr. Run low pass filters before the linear and one after to filter them out to some degree. The SWR of a circuit is if you excuse the expression, for the protection of your radio transistors. Antenna anaylzers are the best way to tune up. I have been involved in radio since 1968 and I don't own one yet. I might buy one just to see if it makes a difference,
But this is just my opinion.
