Just to let u know a few things...
1) UHF and VHF are both frequency range...
2) MHz (Mega) is not a frequency... Hz (Hertz) is a measuring
unit for frequency... There's also KHz (kilo), GHz (Giga)...
3) Whether ur antenna can receive UHF and VHF actually depend on
the antenna spec, IE: Wat's the freq range it can receive...
4) Next just adjust accordingly to the band range to receive UHF
and VHF... Just like radio, if u wanna listen to 93.3 then u'll
adjust the radio to receive 93.3 bandrange... of coz for UHF and
VHF, the band range is much higher then a radio...
