Sure does... the environmental conditions make a yagi/LPA a BAD choice:
wind-driven rain entering traps
high winds (hurricane takes out antenna)
lack of space ( a Hy-Gain 3-30Mhz log periodic WOULD
look good!)
changes in ship's heading would require constant antenna
positional changes
and these are the first ones that a 'ground-pounder' could
think of!
I think it says that a vertical is the best survivable choice -- given all
possible conditions.
