It is possible at one mast install two slopers that cover all traditional five HF-Bands- 80,- 40,- 40,- 15 and
10- meter. Figure
1 shows the antenna.
One sloper covers 80 and
10- meter Bands another one covers 40, 20 and 15- meter Bands.
Each sloper feed through separate coaxial cable. It is possible
use 50 or 75-Ohm coaxial cable. Coaxial cable matched with antenna
with help of length of two wire line. It may be open line or two
wire line in plastic insulation.
For example, at the Figure 1 it is shown at right- two
wire open line and at left- two wire ribbon line. Line in plastic
insulation should be shortened (factor 0.82) compare to two wire
Coaxial cable may have any length. However, coaxial
cable in length 13.65 or 27.30- meter for 40, 20 and 15- meter
Band antenna and coaxial cable in length 27.0- meter for 80 and
10- meter Band antenna would give good result. The antenna gives over 0.5- 1.0- dB compare to VS1AA.
