Simple Broadband Antenna for the 40- meter Band

 

 

 

Figure 2 Free wires at initial installation of the antenna

 

The wire was dug in the earth at depth near 10 centimeters. The wire was connected to the Artificial Earth of the Helical Antenna (Reference 1).  The antenna fed by a 50-Ohm coaxial cable. The cable was attached at upper side of the fence then went down to the ground and lead in to the basement through a ventilation hole. Figure 3 shows schematic of the antenna.

 

Picture 1 shows Feed Point of the Simple Broadband Antenna for the 40- meter Band. Picture 2 shows Center of the Simple Broadband Antenna for the 40- meter Band.

Picture 3 shows Tuning End of the Simple Broadband Antenna for the 40- meter Band. Picture 4 shows Coaxial Cable going along the Fence. Picture 5 shows Coaxial Cable going into my Basement. Take attention, there are three cables are going into the basement. One coaxial cable fed Helical Antenna (Reference 1) second coaxial cable fed the Simple Broadband Antenna for the 40- meter Band and the third coaxial cable used to for my experimental with antennas (in free from experimental time a 144/430- MHz antenna is connected to the cable).
