Topband: Phasing low band antennas???

[jlopez at plasticosomega.com (Javier Lòpez)]

HI,

I would like to hear opinions about how can I obtain better directivity if 
feeding a Titanex V-80 (40, 40 & 160 mts) I install about 33 ft in straight 
line a Butternut HF-2v w/160 mts kit.

May I use the HF-2v as passive element, if do so How???

The separation between both antennas will be 1/16 wavelenght in 160 mts, but I 
have no chance to separate more due lack of space.

Ideas welcome.
