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

Ahha... Please take note this is not my radio shack or work bench. I don't have one. This is the backyard of the house where you can sit there for a drink or meal while enjoying the chat or sun. The umbrella was removed, so i put mine antenna there. ready made mast. Hihi
This is LW's style of 3 element tape measurement antenna.
Another photo of 3 element antenna.
Try to put the antenna high aboe the ground, so decided to put in on the umbrella mast while enjoying the sun.
Mine VHF SWR Meter.
Make sure reading is 0.
PTT...Hang on.... yes! Close to 1:1 at 144.600Mhz. Can you see now, is close to 1:1. IF you still can't see the reading, click on the photo for a larger version.
2 Element ready for the test.
Another photo of 2 element. Well well... This is the lowest I can get. After all the SWR is still below 2 and will not much going to use for PTT, so not to worry about.
Reading shows VSWR 1:1.8.

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.. ^_^
