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.
