N4LQ 160-10 Multiband Doublet with Auto-Tuner. Post 1940.

If you want multiband HF coverage from 160 meters through 10 meters and you can have only one antenna, why not try the "classic" doublet antenna?

In this video, Steve Ellington (N4LQ) show us his doublet antenna which covers 160 meters to 10 meters, using 60-ft/18.29 m of 450 ohm ladder line and a MFJ-998 automatic "tuner."  Steve says his length of balanced feed line, coupled with the "tuner" allows, him to cover a wide range of amateur/ham radio frequencies.

If you want to follow Steve's design, please cut the doublet for the lowest frequency of use.  In this case, you will be able to cover 160 meters to 10 meters with each dipole segment measuring approximately 135-ft/40.76 m.  You may have to adjust antenna length to accommodate local conditions.
