Jorge,
The apex would have to be much higher then 11o' for the
antenna to be effective on 160 meters. With 160 meter long
legs (about the minimum that still works) the apex would
have to be at 100 meters. With a 110' apex you could
create a good antenna for 10 to 30 meters for a single
direction.
I have modelled this configuration last year when planning
a DXpedition to Castle Island (C6AGU) where the top of a
120 foot tall light-house is accessible. (I love Vee Beams
and look at any tall structure as a possible support for
one.) Unfortunately, for 160, the support would have to be
much higher than 120 feet.
