Antennas UA6AGW

 

 

I believe that antenna arrangement according to Figure 1 has optimal parameters. SWR of the antenna was less 2.0:1.0 at the pass band 200- kHz. In the vertical plane Antenna has DD similar to an ellipse with a maximum in the radiation along the horizontal wires. Vertical plane radiation is going at the angle near 25- degree. In the horizontal plane the antenna has almost circular DD.

 

Antenna for the 80- meter Band

 

Figure 5 shows sketch of the antenna.

Loop of the antenna made of a length a coaxial cable in diameter of 1-1/2 inch.

 

Horizontal wires are located parallel to the ground at the height 3.5- meter above it. Such antenna design was taken by me because of the local conditions and my possibility. Capacitors are placed in the plastic box. Figure 6 shows a picture of the antenna. Figure 7 shows the plastic box with installed inside capacitors. Coupling Loop made according to Figure 8.  Horizontal wires have diameter 2... 3- mm. Copper strand wire or antenna cord may be used for those ones.
