[TowerTalk] ANTENNA HEIGHT

[k2drn.cw at verizon.net]

i currently use a multiband 133' dipole for HF dx and want to go to a tower 
with a 10 thru 30 meter yagi, maybe a steppir.  My property is loaded with 
ash trees approx 60 to 70 ft tall.  will the trees be a problem if i choose 
a tower not tall enough to put the antenna above them.  I occasionally get 
wind gusts up to 60 mph.  all my interests are with HF dx.
