Thanks for the $.02 worth...it would be a good idea for me, but I will have
several antennas (of various types - dipoles, vee beams, etc.) capable of
being used for the same band, but at different angles from each other. I
hate to "share" my antennas and mess up the patterns I want to use. I
thought about switching way out back, but kind of hard to do A-B testing
when I have a 500 foot run to switch the antennas and get back to the shack!
I'm too old for that!

Why not just run one pair. Then split off at the end with the antennas.
The signal will take the path of least resistance, so the most likely
antenna for the job will be chosen automatically. The ones with high Z
will
resist. Resistance is not futile.

My 2¢ (that "¢" key was tough to find)

I need your advice, as I have never worked with open wire lines before.
I need to feed many different antennas with open wire line and need to
run
the feeline from each about 200 feet from the back pasture to the shack.
I
don't want to walk out 200 feet and throw knife switches to chose the
antenna/feedline I want to feed, so I plan to run separate 600 ohm open
feeds for each antenna all the way to the shack.
The problem is I don't know what the effect is or how to handle the
multiple open wire feed lines, as they will be parallel for probably
150-200
feet. I haven't found anything in literature describing this.
For instance, will they interact? how far do you space the feedlines from
one another? If I have 4 feedlines, can I stack them vertically or
horizontally one foot apart from each other? How much is enough
separation?
What other precautions do I need? Need they be twisted if they are not
near
anything other than the other feed lines?
Any help is appreciated.
