A good ground is also necessary for optimum performance. Remember, we are dealing with long wavelengths here, the middle of the AM broadcast band is 300 meters wavelength contrasted to the FM band which is about 3 meters. Your little UHF bowtie is designed for even shorter wavelengths ( 60 centimeters or so)... not much help for the AM radio band.

Yup !

I got an old SC 60, Super Het. but still works like a champ with a good
ground, and a good long antenna wire..... I had 120 feet and wow it
pulled in good am and the sw was just amazing....
