A world class contest station with wires and no towers not on oceanfront is
just about impossible. You can build a good station with wires. My
suggestion for 80 is what has been very successful at two different locations,
I
have constructed two element looped arrays for four different directions.
They
are flat top delta loops and if you can get them so the tops are around 90
feet they will play very well...close to what a 4 square vertical system would
give you. I use lots of rope to provide support to the loops. You could
suspend the ropes from pulleys in the trees to do the job.
On 160 I would suggest a wire vertical suspended from ropes. You could get
the top up to around 90 feet and top load it using a couple of wires along
the rope.
The loop concept could also be used for other bands and if you built a
system for 40 it would perform similarly to a three element full-sized Yagi at
arouond 70 or 80 feet.
There is a ham in Indiana who has a 10+ wire loop 40 meter system facing the
Pacific. He is LOUD.
My yard in Florida looked like a trapeze act practice area...but the loops
at around 120-140 feet at the top absoltely screamed.
