Antennas are 'tuned' buy the length of the metal elements. When UHF signals are strong a VHF antenna will receive UHF. When VHF signals are strong a UHF antenna will receive VHF. And then there is the resonating frequencies at fractions of wave lengths. I do not get in to all this when I am dealing with question askers , it only serves to confuse the question askers. I stay with UHF is UHF and VHF is VHF . AD Tech lets his tongue slip on this UHF,VHF from time to time and it gums up the works. It's a full time job keeping question askers on the right path. The question askers are mixed up enough to begin with and are using every kind of wrong antennas and amplifiers and then some.
