Thanks to all the responded to my last email. Here is what I did. I removed the polarization switch and connected a VNA to the antenna . It said the impedance is 32 J17 ohms  VSWR 1.84:1 center around 145MHZ  Questions

  1. Does this measurement look right?
  2. Should I try to match it to 50 ohms
  3. If so, what is the best way do it
