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
