	It probably won't work worth a poot, simply because your body is 
going to act like a parasitic radiator and change the antenna's gain
characteristics.

	Fortunately, RCA do make an antenna for people in this predicament.
We used (way back in 1976) to sell a weatherproof, but electrically short
directional antenna called the RCA Mini-State.  This is no substitute for
a proper full-size antenna but is very good, with a decent directional
pattern (particularly at UHF) and gain for driving the transmission
line.  It comes with a little controller that you can point the thing
via wired remote control, and is sealed in a radome.

	When I was at UNC-C we had a poor man's Yagi silly-puttied to 
the roof and pulled in Greensboro stations well.  Then again, on the
tenth floor of Holshouser.....

	For UHF, try one of those things that looks like a hibachi rack
with two bow-ties on it. It's fairly directional and much better than
rabbit ears...
