A single mast (Fig. 1) posted two antennas, one for 10 and 80 m. the second on 15, 20, 40 m, each of which is powered by a separate cable. Cables can be run either from the two-wire overhead line wire from with a diameter of 2 mm with a distance of 100 - 150 mm, or from wire CAT. In the latter case, to reduce the length by the velocity factor of 0.82. On Fig.1 schematically shows the plumes from different material.

Length coaxial cables is not critical, but best results are obtained by using the cable or 13,65 27,30 m for 15, 20, 40 m and 27 m for 10 and 80 m. in spite of short-emitting part, on 80 meters this antenna better than VS1AA from 0.5 to 1 point.
