VSWR relative to 50 Ohms vs. frequency

 

 

VSWR relative to 75 Ohms vs. frequency

 

 

Conclusion for the connection shown in Fig. 1: The autotransformer can be used in a transmission and reception mode on a range of 80 meters while this one loaded to 600 Ohms. (An antenna Beverage

 

or T2FD can be such a load.) The autotransformer should be used with a 75-Ohm coaxial cable. The maximum of the RF power going to the transformer must be limited to 50 watts.
