* Antenna Calculator: handle out-of-range frequencies
Fix an out-of-bounds read in update_result(): when the required
quarter-wave length was shorter than the fully-collapsed antenna, the
element interpolation indexed elements[-1]. Guard the frequency range and
report 'retracted' (above the fundamental range; a wideband RX whip still
receives here via harmonics) or 'fully ext.' (below range) instead of a
garbage element count.
* Add Comet W100RX to the sample WHIPCALC/ANTENNAS.TXT
Comet W100RX telescopic RX whip, segment lengths (mm) from the Comet
W100RX instruction sheet: 200/300/400/510/615/800/986.
