TV's coaxial cable is 75Ω as opposed to your 50Ω transceiver - it won't make much difference receiving, but can cause problems transmitting.
Also, it could be you're listening to a repeater input, try adding 600kHz to your frequency and see if you can hear the group.
VHF only describes a range of frequencies between 30MHz and 300MHz, the usable resonance of nearly all antennas is only a couple of hundred kHz, so, if your antenna is tuned for 50MHz and you're tuning your receiver to 145MHz only a tiny fraction of the signal will be "scooped" up by the antenna.
Antennas can get expensive. For VHF & UHF the coax can cost as much as the rest of the station. I'm not trying to put you off, but good coax is the difference between contact and no contact on those bands - start saving and enjoy!
