You have leverages to consider that will complicate matters.  If your winch 
is mounted 30 feet higher than the swivel point and the 150 pound 
antenna/rotor is 120 feet from the swivel point the winch will see 600 
pounds of antenna.  Add 285 pounds for the yagi at 90 feet and 110 pounds 
for the yagi at 60 feet and you have 995 pounds of dead weight before you 
start to consider the tower.

I'm not an engineer but just for yucks say the top half of the tower (less 
antennas/rotators/guys) weighs 1000 pounds.  The leverage here is between 
times 2 and 4, call it 3 for talking purposes.  You will be pulling 3000 
pounds of tower at the winch.

You will be pulling far in excess of 4000 pounds when the tower is 
horizontal.

And then you will require swivel boom to mast clamps so the antennas will be 
horizontal when the tower is down and swing to their horizontal position 
when the tower is vertical.

Not to mention that the area where the tower/antenna/guys swivel down to 
will have to be clear of obstructions and fairly level.  And the set of guys 
that are on the far side of the tower will tangle when the tower is lowered.

Other thoughts: the antennas will require maintenance, and not all antennas 
will require that maintenance at the same time.  And if/when the system is 
no longer wanted what happens to the modified house?

I have removed many antenna/tower systems for estates (I keep what I take 
down for my fee), but for what you are talking about - don't call me.

I suggest you do as a friend of mine did with his pair of 100 foot towers 
and multiple antennas:  hire Steve, our reflector host.
