One of the things that could hurt the vertical effort, may be the local noise 
level. One may want to have a back up plan.. that could be as simple as simply 
running a long piece of coax out.... I know..heavy... but think shielded and 
quiet. If the site is overwhelmed in noise on the vertical, keep it, use the 
coax as a second.
  A slightly different antenna that may work with less fuss, is a 40 or so foot 
high vertical radiator, with top installed guying insulated low guy lines. Four 
do fine, then at the bottom of the vertical, an omega match consists of a pair 
of capacitors, vacum type if you run power, The caps allow you to match exactly 
to the feedline, with a wattmeter at the antenna, on 160 - 80 - 40. No lossy 
coils. 
  On the beach where the ground losses are low... this antenna would shine very 
nicely. The majority of losses are simple ground loss. In Wy, you would need at 
least 32 radials, on the beach.... one... maybe two. 
  Good Building... --... ...--Dale - WC7S in Wy
