Ten Tec fans:  In a recent article in Electric Radio Magazine, a former ARRL 
employee of many years, Mr. Lew McCoy, explained why mobile antenna designs 
like the "Texas Bug Catcher" are superior moble antennas.  The reason is that  
the large capacitive hat raises the current loop and therefore the radiation 
near the top of the antenna.  This greatly increases the efficiency of any 
short, base fed antenna.  Without a capacitive hat the current and therefore 
the radiation is mainly concentrated near the base of the antenna  and most is 
wasted in heating earthworms.  This was explained years ago in the old ARRL 
book "The Mobile Manual for Radio Amateurs" , long out of print. -73's- K4OWN,
