Topband: Best way to jury rig a quick 160m contest antenna?

[Tree]

You are not going to work a lot of multipliers in the IARU contest on 160
meters - even if you had "real" antennas for the band.

I would suggest either just loading up your 80 meter antenna and working
one or two mults and then go back to focusing on the other bands.  The idea
of using it against ground is a proven method for doing this (as previous
posted).
