The antenna, named as Pyramidon Antenna, is very simple to do. It is a broadband antenna so it is cover a wide range of the 50- MHz band and the antenna is not critical to the dimension. Figure 1 shows design of the antenna.

Antenna is installed at 3.1 meter height plastic mast. However the antenna is not critical to height above the ground and material of the mast and may be installed at metal mast. File MMANA allows play with the antenna according to the height above the ground and the material of the mast.

Two wires in 0.92-m allow tune the resonance of the antenna along the 50- MHz band.

Figure 2 shows Z of the Pyramidon Antenna for 50- MHz Band. Figure 3 shows SWR of the Pyramidon Antenna for 50- MHz Band. Figure 4 shows DD of the Pyramidon Antenna for 50- MHz Band.
