[Elecraft] Really OT: Inside-the-vehicle HF antennas (possible bonus points)

[Alan]

One of my colleagues at HP told me he once made a CB antenna by feeding 
the front window of his car between the rear-view mirror and the dash. 
Basically a big slot antenna.  He claimed it worked great.  I don't 
remember how he said he matched it to 50 ohms.
