So, it would be about a 1/8 wave on 160?

Why would it not work as a 1/4 wave on 80m?

If I insulate the side-mounted beam by covering the mast with
PVC will its proximity, even if electrically islolated, cause a 
problem?

80m is far more important to me for emergency communications
than is 160m.  Are there changes in the configuration of the 
tower and antennas that would make it more suitable to 80m
use?  Must I eliminate the side-mounted beam entirely?
