Topband: Beet Antenna Choice?

[Edward]

Greetings,

I have four choices for a TX antenna on 160m.  Your input as to which would work best would be greatly appreciated. 

1) Shunt fed 106' crank-up tower with some top loading from a Steppir DB-36 plus VHF antennas on a 20' mast.  

2. Shunt fed 89' crank-up tower with a multi band HF beam plus some VHF antennas on a 20' mast. 

3). Inv L, using 106' crank up for support and running remainder of wire to nearby tree. 

4). 80' Eucalyptus tree about 20' from crank-up towers for Inv L. 

Radials available for all. 

Thanks,
Ed NI6S
