[TowerTalk] OCF and 160m?

[Eugene Hertz]

Hello all,
ok: I got a real bender for you experts and modelers out there (I am neither!).

I have two trees on my property. They are 195' apart. I am thinking of an OCF dipole with 45' and 90' legs with a 6:1 autotransformer at the feedpoint connected to 50 ohm coax (buckmaster style).  This nicely brings the feedline directly over my shack.  But, I have lots more length available to me to the far tree that is going unused.

I was thinking of a way to use that space for 160m instead of rope.  Here's my thought and could someone tell me what I'm smoking or if it may be feasible?

Do you think it might be feasible to place an 80m trap at the end of the longer leg of the ocf, and extend a wire beyond the trap for 160m. The idea would be to use only one of the coax conductors against a radial field for 160, but use the antenna as a OCF using both conductors for 10-80?

In that way, I can get both a balanced 10-80 meter ocf AND an inverted L unbalanced antenna for 160 using the same installation (not at the same time, of course!) Any one know what the existance of a trap and extra wire beyond the trap might affect the OCF performace when being used as a regular ocf?

Just wondering your thoughts. I will add that several folks have reported excellent results with the carolina windom, but I do not mention that here because it has som other baluns involved that might complicate any calculations/modeling of the idea I have above.  So I have listed the simpler buckmaster just for ease of discussion.

Thanks!
Eugene
