How should the antenna on a hand-held transceiver be positioned while
you are transmitting?

Away from your head and away from others standing nearby
Pointed in the general direction of the repeater or other station you
are transmitting to
Pointed in a general direction 90 degrees away from the repeater or
other station you are transmitting to
With the top of the antenna angled down slightly to take the most
advantage of ground reflections
2I-5.2

Why should you always locate your antennas so that no one can come in
contact with them while you are transmitting?

Such contact can detune the antenna, causing television interference
To prevent RF burns and excessive exposure to RF energy
The antenna is more likely to radiate harmonics when it is touched
Such contact may reflect the transmitted signal back to the
transmitter, damaging the final amplifier
