20m 1/4 gp tuning

Checked using the vswr meter on the radio ....

Initial ....

14.0    1.6:1
14.1    1.5:1
14.2    1.4:1
14.3    1.4:1
14.4    1.4:1
14.5    1.6:1

Going to #1 add to the vertical element 18" to drop the VSWR aiming for 14.0 @ 1.4:1 then #2 I am going to add another 8 radials and see if I can get the VSWR down further.  

With the added 18"

13.9    1.8
14.0    1.6
14.1    1.6
14.2    1.6
14.3    1.7
14.4    2:1  

So no doubt the optimum is lower but the overall VSWR is suffering.  So now its about the radials .....
