[Antennas] Half wave vertical question

Mon Dec 6 04:21:29 EST 2004

I have read that the impedance of a half wave vertical CAN be several 
thousand ohms. My question is how many thousands. The feed point will be approx. 6 
inches above ground at my location. I have 6 quater wave radials in place. I 
am trying to match this antenna to a TinEar receiver that I recently built. It 
 requires a 50 ohm input. I would like to wind a torroid transformer to match 
 these two, but don't know the ratio I will need. Any help would be 
appreciated. Rick
