Such a low dipole will normally have, at its center, an impedance in the general range of 4-j60 ohms at 7 MHz, so the r value you're seeing doesn't seem surprising. For all practical purposes it's on the ground and the earth has a very large effect on its impedance and its resonant frequency. In

So, if I understand you right... Sorry about getting OT here. I can make it resonant by extending it about 1 foot on each end? 33 feet/x=7.09/7.3 x=~34 My main problem are junipers. I can raise the antenna about 20' in the air but then the antenna is literally in the trees. Would that
