[Elecraft] KPA500 mobile?

[KENT TRIMBLE]

The assumption has always been that the driver and passengers are riding 
inside a Faraday Cage and therefore are safe from RF radiated by an HF 
antenna, regardless of where located and regardless of power level.  The 
truth of that assumption, coupled with how much shielding a vehicle 
actually presents, is worth considering.  Until the RF Exposure business 
came along, no one considered safety for those outside the car.

Less and less body-metal, roofs made entirely of glass, more electronics 
both on and inside human bodies (over and above the vehicle's 
electronics), the close proximity of the antenna . . . all of which, in 
my opinion, argue for a re-think of high-power mobile operation.

In the 1970s I greatly enjoyed mobile CW with an FT-101E until my first 
child started occupying the rear seat.  After she came along, I opted 
for no further mobile work of any kind, at least when she and her 
siblings were in the car.  I'm not a geneticist, but neither am I 
willing to push my luck with the gazillion of cell-divisions going on 
every second in a child's growing body.

Excellent question to ask, Lynn.
