As you can see there are the exotic and erotic aerials. You can be whirl wide or somewhat local or DX can happen.
A VEE is convenient and can give you DX. If your goal is strictly DX then you should look at verticals or stacked antennas like Tom.

BUT The HuzMan has a very nice all around solution that works very well and been known to hop an ocean or two.

Fullsize dipoles for 160, 75 and 40 using single coax feed and homebrew 1:1 balun.  Elements are paced 5" apart using 1/2" PVC as spreaders.  Works well, very well considering it's only up about 50ft. at the apex.

Another nice solution that would not be a far out project.

Lots of guys have been switching to maypoles.   They seem to have a big signal here in the state. Now you can by fiberglass pushup pole masts cheap..  You could put this up in an afternoon easy.

Also.. I have been hearing a few guys using the S9 vertical.  Its about $150 with Ground radial kit  One guy can put it up. Not sure about the performance on 80 with the big coil but on 40, they sure put out a big signal.

I use a "full wave" (300 feet of #14 wire) 80 meter loop, sorta triangular in shape, up about 40 feet between 7 trees, driven on one of the long sides with 25' of 450 ohm open wire directly to a Heathkit 2040 tuner in the shack.

The Apache doesn't do 160, so I use this on all the other bands with great success.

Random wire, 180 or so ft., unknown exact horizontal length fed by single wire feeder about 1/3 out from end by "L" net homebrew match. Works 160 through 6.
Lobes on higher freqs. are so numerous that coupled with real losses and tree attenuators, it must look like a perfect circle.  Grin

Just about anything of reasonable length matched properly will load the aether up nicely.

Some have even heard 'it' on the air.
