Yes one factor, when the wind blows and causes antenna wire movement because the
Q is very hight for litz wire and the bandwidth therefore is quite narrow, the
antenna goes off resonance, and not good for the PA, you could easily Zap the
transistors. Because of over all losses using small antennas on LF the advantage
of using litz is only marginal over convential 2- 3 mil insulated wire.
