I have a 585' NE beverage I recently put up that uses 5' steel conduit supports with PVC pipe insulators at the top (~ 7' height).  I have cut slits at the top of the PVC pipes and run the wire through those.

Google is your friend.  A search for two wire beverage will result in 
several useful ideas.  The link to the following article represents what 
I consider to be the best way of doing the switching, alluded to by Greg 
in his comments above.  I've used this technique in the past and will be 
erecting a NE/SW edition of the antenna later this winter......or 
possibly next spring, depending on how the move to the new QTH goes.
