Re: Hi SWR on 40 meters

Kyle,
The 5 turns did the trick and it is tuning great now, thanks for
your help!

Bob,
You could try two things:
1. Put about five turns of coax about 5 inches in diameter at
the base of the antenna.
2. Put a few turns ( 10 X 1" ) of #14 gage wire at the base of
the antenna.

I'm just guessing here but, good luck!

Kyle, thanks for the response. I did play with it a little last
night and noticed that it does tune from 7.050 to 7.200 but any
higher will produce high SWR.... I will try adding the Ground to
the base of the whip and see if this helps... When you say a few
turns of coil at the base of the antenna are you talking about
coiling the coax and making a choke? Again, thanks for the help.

The Ham Stick has inductance. Add a few turns of coil at the

of the antenna.
OR improve the bumper to chassis ground. or Both.

Make sure the tuner is close to the base of the antenna.

Just installed the Ft-857D, FC-40, Hustler bumper strap mount
and 102"
SS Whip in my truck. It works on all bands but 40 meters (high
SWR) I
have tried extra lenght of coax added to the supplied coax. I
have
added Ground cable from tuner to frame and still no luck.... I
did
put
a 40 meter Ham Stick on it and it tuned it no problem. Any
suggestions
would be appreciated.
Thanks
Bob
