How about five elements on 80M over three elements on 160?

The tower is 300 METERS tall. Need a bit more than an acre for this one!

Are you thinking rotatable yagi or fixed wire yagi?

Don't rule out phased arrays or reversible beams if you'd be inclined to consider something along those lines.

Of course if you can afford it and are in the market this 40m monobander would be excellent.

That is a monster.
A old timer friend of mine had the largest 20 meter beem I ever saw.

He was the one that inspired me to build my 63 element. UHF that is.

here is a write up about it here.
