If the SWR is higher, the reflected power is higher, The total watts are the
same. The difference is where they go. What you will want to know, is what
is the SWR where you want to transmit. If it is to high, the question is
does it go down if you move up or down in frequency. If it goes down when
you move down in frequency, the antenna is to long. This is where an
antenna analizer or grid dip meter can become really handy. Since they
don't talk, I hope you have a talking or Cw read out SWR meter.
