Half Loop Antenna for the 80-, 40,- 20,- and 15- meter Bands

The publication is devoted to the memory UR0GT.

 

 

It is very simple and efficiency antenna that works in several amateurs bands- 80,- 40,- 20,- and 15- meters. The antenna has input impedance 75 Ohm. Figure 1 shows design of the antenna.
