Below are the photos during the process of tuning the SWR for the antenna.

For the 3 element tape measurement, I did try with 5 inches wire but not able to tune down the VSWR on 144.600Mhz. I decided to do some trial and error, started with 6 inches wire, still not satidfied as able to get 1:1 about 146.600Mhz. So told myself, why not put a 10 inches wire and trim it all the way down. Yes I did follow to my thought. spot on... 10 inches and the VSWR gone down to what I want. Hihi... the 5 inches or 10 inches or the wire is referring to the wire used for hairpin match.
Thanks for viewing the page and hope you have fun too. Hope I did not cause TVI problem to neighbour during the calibration as I think I'm pointing on one of them's TV antenna. WhoOOOps.. too bad.. ^_^
