I have found the easiest single antenna to utilize is the OCF - it is 
coax fed, making easy routing of the feedline. The K3's ATU handles it 
fine (as does my TS-480 SAT).

Dimensions for the version I use:  88' on one leg and 44 ' on the other 
leg. For a center insulator/balun I use the

use #12 stranded insulated wire (not house wire) available from any of 
several ham distributors.

Works FB for what I do with it, which is mostly rag chew on 40 and 75 
SSB. However, I have used on the higher bands with good success also. 
The pattern does get somewhat directional as you move up from the 
primary design frequency. If you have room for a couple of them at right 
angles - that might be of an advantage.
