I have an excellent design for an end-fed SINGLE BAND half-wave dipole, 
but I can't think of a good way to do it for multiple bands.  See the 
slides near the end of my talk on elevating vertical antennas at 
http://k9yc.com/publish.htm  You can build it for about $15 for QRP. To 
handle 100W, you'll need a bigger ferrite core for the choke that will 
raise the cost by about $10.

You can go to the hardware or electrical supply store and buy a spool of 
wire, toss a length of it into a tree or tie it to something on your 
house, toss another length into another tree or something on your 
garage, and load that as an antenna.  The tuners in Elecraft rigs will 
match antennas like that very well.

No.

This is what we call back home in WV where I grew up "a pig in a poke."  
There's nothing on this webpage except testimonials from new hams who 
appear to be technically illiterate. When someone tries to sell you 
something without telling you what it is, run like hell in the other 
direction.
