I would be a bit worried about the xponder antenna frying my brain - thus I
like it under my bum with a circular 5 1/2 inch circular ground plain (if
glass glider) so nothing gets into my body except the bottom part of my
legs and they do not matter. Xponders put out a lot of power!!

Not that much on average, really. Each pulse is high power, but the
average is only a 100 milliwatts or so, except in the very busiest
airspace, where it could be a couple watts. When I wrote my transponder
articles for Soaring a couple years ago, I couldn't find any hard
information about health effects (or any information, really). Still, I
prefer to mount my antenna much as you do (mine is just behind the gear
doors), and the carbon fuselage of my glider blocks most of it.
