2 times the seated height of the antenna which is 2.6"

A totally bogus recommendation. A few years back, someone observed
that their transponder was rated for 200 watts output . . . 1/3rd
that of the family microwave. Our hero was immediately concerned for
preservation of the family jewels and proceeded to line the bottom
of his composite seat pan with aluminum foil. What he failed to
understand was that his RF coffee warmer and popcorn popper was
rated in continuous watts while the transponder was in peak watts.
The average power output from a transponder is less than 1 watt . . .
BTW, the eyes are about 100 times more sensitive to the effects of
microwave heating than are any deep organs . . . you'll go blind
you quit making babies.
