Windom is one of the oldest and reliable antennas that used in ham radio. There are lots modifications of Windom Antenna (or in other words Off Center Dipole Antenna). One of such modification was optimized by UR0GT. The antenna was optimized for 40, 20 and 10- meter bands. The main advantage of the Windom Antenna is that the antenna may work at several bands with low SWR.

It is possible get by choosing the point of feeding of the antenna and lengths short and long parts of the dipole antenna. Height of the antenna as well influenced on the input impedance and resonance of the antenna. It would be useful to check the antenna in MMANA before antenna installation.

Simple broadband transformer 50/200- Ohm that may be used with the antenna described at Antentop- 01, 2015, pages 96- 97, Broadband Transformer 50/200 Ohm by RZ9CJ.
