butternut and 17 meters problem
 

Greeting!

I am having problem tuning my new Butternut HF9V vertical on 17 meters.. My
antenna is ground mounted 60 feet from the house or anything else. I have 40
radials surface mounted just under the grass... The swr on all the other
bands is about 1.4 to 1 or less, but on 17 meters its 2.4 to 1 causing my
ft-847 to fold back power.. Though! the high swr, I am still able to make
contacts to Europe and other DX on the band with little effort with less
than a 100 watts... I do have a MJF-259 analyzer and still have problems.. I
have spent hours at attempting to get a lower swr

Any Help would be appreciated

Thx in advance ` 73

Easy solution - use a matching network (tuner) on 17m. What does the
MFJ-259 say the 17m impedance is looking into the feedline. How long
and what kind of feedline?
