Hi Mike

You can place a brass machine screw in the pipe caps for fine tuning.
EG moving the center frequency up and down. (vertical screw)
Changing the impedance slightly (stub screw)
Adjusting the SWR is by moving the coax connect point up or down
slightly.

Hi Fella's

I have recently built a J pole for 2 meters from the handbook and I was
wondering if any of you had some tuning tips.

Thank you in advance.
