[Elecraft] OT: Portable Antenna for K2

[Dave White]

I'm looking to take my K2 (10 watt) on holidays where we will be staying at 
a 3-story lodge high atop a bluff overlooking the ocean.  The lodge is 
surrounded on 3 sides by some tall trees. The roof of the lodge has a table 
that I can operate from. I haven't seen the location first-hand, but I 
assume I can throw some wire from the roof into the trees.  I have a 1 to 1 
balun available and some lengths of "disposable" wire (about 50 - 75 ft) 
that I can devote to the project.  My K2 has the KAT2 ATU built in.  I don't 
want to spend any money on this, so a commercial antenna system is out.

Any ideas on the best configuration to use? Should it be a simple long wire? 
Should I use the balun between the radio and the antenna?  What about a 
ground system?

Thanks
