Fig. 3.24 Miniature VHF radio beacon (version 2)
with an antenna for the entire length of the tie, which will increase the range up to
500–1000 m. Such radio beacon can work for 1600 h without recharging.
The antenna of the radio beacon installed in the heel (see Fig. 3.26) is placed in
the sole of the shoe. Since heels are mostly hollow inside, fitting them with such
devices is relatively easy. The top of the hill is rotating, which helps replace batteries
and tune frequency.
