If you can have only one HF antenna to cover the Amateur Radio Bands from 160 to 10 meters, then this multiband doublet by Steve Ellington (N4LQ) may be what your're looking for.
According to Steve, this doublet "cover(s) HF bands with great results...the MFJ-998 tuner easily loads the antenna on several bands. The 60-ft/18.29 m of balanced feed line, coupled with the MFJ-auto "tuner" provides a suitable match to his transceiver on Amateur Radio bands from 160 through 10 meters.
You can also build a similar antenna to cover 80 through 10 meters if your space is limited. Just design the antenna for the lowest frequency of operation, use balanced feed line, a balun (if needed), and a well-built antenna "tuner." The doublet is an excellent, efficient, and inexpensive way to cover several Amateur Radio bands with one antenna.
