Short multi-band HF antenna for those without a large garden.  At only 20.28M in length (66 foot) this off centre fed dipole antenna will operate on 40M (7MHz), 20M (14MHz), 15M (21MHz) and 10M (28MHz)and  the WARC bands.  Impedence matched by a 4:1 balun transformer at the feedpoint can be fed with 50Ohm coaxial cable via an ATU or AATU (internal or external). Can be mounted as a horizontal, sloper or inverted Vee.  Can handle up to 400W (CW).  Best mounted at least 25 foot above ground.

During tests the following measurements were taken:

Direct feed:

MHz                      VSWR

7.100                    1.3

10.100                  2.3

14.200                  1.9

18.100                  2.3

21.200                  2.3

24.930                  1.2

28.200                  1.1

50.070                  1.9

With ATU:

7.100                    1.1

10.100                  1.1

14.200                  1.1

18.100                  1.1

21.200                  1.1

24.930                  1.1

28.200                  1.1

50.070                  1.1

This is a low cost, low visibility, high performance antenna.
