Hi Ralph,

Get 100 ft of 450ohm ladder line.
Cut off 34 ft for the feedline.
On the 66 ft piece, solder the end wires together.  Attach insulators.
Cut one side of the 66 ft piece in the center and solder the feedline in there.
On the 66 ft piece, opposite the feedline connection, cut out 4 inches of the wire on that side.
What you have now is a folded dipole.
Make something like the Acro-Bat antenna hanger from Ten-Tec to support the center.
Connect the 450 ohm ladderline to the Elecraft BL1 4:1 150W balun.
Connect a short, 3 ft coax jumper from BL1 balun to the rig. 
Easily tunes 80-10.  

Also very effective is a single wire dipole, 33 ft on a side, 
fed with 300ohm tv lead via Elecraft BL1 4:1 150w balun.  

Good luck,
73 de Joe, aa4nn
