- The Ugly MacGyver 6 meter J-pole Antenna
- Essentially, a J-pole is a 1/2 wave resonant antenna connected to a quarter wave matching stub. The feedline is connected at a point on the matching stub that is at the feedline's characteristic impedance. The result is 3/4 of a wavelength on one side and 1/4 wavelength on the other side.

- 2 element Yagi for 50 MHz
- This 6 meter 2 element yagi antenna is simple, compact and effective antenna for 50 Mhz. The design antenna was optimized with AO for best match to 50 ohms, no matching network. A choke balun is recommended to decouple feedline currents.

- KC0KJF Doble Bazooka
- The Double Bazooka Dipole is a very efficient single band antenna which is very quite,and does not
require the use of a balun. This antenna consists of coax (RG58) with the shield split at the center and the feedline attached to the open ends.
