Comet GP-15 tuned for 6 m band

After trying out my new Rigexpert Stick 230 on my Comet GP-15 vertical, found the SWR on 6 m not too good...resonant just above 54 Mhz out of band.


Had a look at the antenna. There is a tuning stub on one of the 3 radials that you can slide a rod in and out. I had it in most of the way, tried sliding out as far as it would go.

The analyzer readout now looked a lot better 😀

Resonant around 50.9 Mhz. Good enough for using on the SSB call frequency 50.110 and the FT8 frequency 50.313.

Plugged in the IC7300. SWR plot around 50.313 Mhz


Under 1.5 to 1 SWR. Turned on the inbuilt tuner, this tuned it up nicely.


So good to use on 6m. As the middle of winter will have to wait to test it out.
