[Towertalk] Rotating Dipole

[David Jordan]

Hi Folks,

This weekend I took two old Butternut HF6V vertical antenna and mounted 
them end to end to create a rotating dipole.  I had been using them as a 
phased array at a past QTH and they were just in the aluminum pile at 
the new QTH.

I was surprised that the dipole tuned up right in the middle of the 40m 
phone band with a 50 ohm input impedence.  What am I missing?  I thought 
for sure the input impedence would have been lower than 50 ohms!

thoughts,
