Jim, It all depends what you want to accomplish on 160 meters.
An inverted V with a feedpoint at 80 feet above ground will be an NVIS 90 degree TOA antenna which will allow for rag chewing out to approximately 500 miles. As an inverted V the ends should be high enough so that a animals and people can't run into them. Also high enough so that at the feedpoint the wires are no closer than 90-120 degrees apart from each other to prevent RF signal cancellation. If you feed the inverted V with coax you may see a bandwidth of approximately 50 kc. You can then use a tee network antenna tuner to fool your rig or linear amplifier so as to be able to operate across more of the band with some loss. With window line and a balanced link coupled antenna tuner you can operate across all 200 kc of the band with virtually no loss. I use 300 ohm window line on my 160-10 meter full wave horizontal loop and bring it into the radio shack via a piece of 1" x 4" oak board with banana jacks through it. You want to keep the window line at least twice it's width away from metal to reduce interaction, so running it through metal conduit and parallel to other feed lines would not be good. A good compromise antenna for DXing and rag chewing is the 1/4 wave inverted L. I have a website on the 1/4 wave inverted L at http://www.kn4lf.com/kn4lf97.htm . 73 & GUD DX, Thomas F.
