Hi
Well, not exactly, but close. A half wave on 160 is 260 feet, half of
that is not 140 as in the Cobra and 80 meters half wave is about 134
feet, so half of that is not 70 feet, as in the Cobra antenna. But its
a good enough starting point to work with I suppose. Maybe I'll try 35
feet for 40 meters.
Thanks
Jim
