Delta Loop for 40- and 20- meter Band

The publication is devoted to the memory UR0GT

 

 

By: Nikolay Kudryavchenko, UR0GT

 

 

 

Antenna has good SWR on both 40 and 20- meter Bands. Antenna placed on distance 2- meter above real ground. Input impedances of the antenna on both bands depend on distance above the ground and condition of the ground.

Figure 1 shows design of the antenna. Figure 2 shows input impedance of the antenna on the 40- meter band. Figure 3 shows SWR of the antenna on the 40- meter band. Figure 4 shows DD of the antenna on the 40- meter band.

Figure 5 shows input impedance of the antenna on the 20- meter band. Figure 6 shows SWR of the antenna on the 20- meter band. Figure 7 shows DD of the antenna on the 20- meter band. Diagrams at Figures 2 to Figures 7 showed for antenna placed on 2- meter under real ground.
