There is presented Tin Woodman Antenna for the 50- MHz Band. The antenna is very simple in design. The antenna is electrically closed so this one is safe in a lighting period. Antenna has good SWR at the band. Antenna has 50- Ohm input impedance that allows feed the antenna directly by 50- Ohm coaxial cable. Antenna allows to be made with some tolerance. Antenna installed on a mast in 6 meter high.

Figure 1 shows schematic of the Tin Woodman Antenna for the 50- MHz Band.

Antenna is fed through a Gamma match with capacitor in 11- pF (should be found the precious value at tuning) connected in serial.

Figure 2 shows Z of the Tin Woodman Antenna for the 50- MHz Band. Figure 3 shows SWR of the Tin Woodman Antenna for the 50- MHz Band. Figure 5 shows DD of the Tin Woodman Antenna for the 50- MHz Band.
