Question about over the air HD channels on LG TV?

I have an LG 37LG50 model HD LCD television. This is plugged into the wall and has a QAM and ATSC digital TV tuner. Some of the channels come up a little scrambled looking, and I was wondering if there is a way to increase the receptionso that the TV doesn't get scrambled and blocked out with jumping audio. I live in an apartment, so I don't really have much access to much.
Are these channels broadcast via the regular coax cable or picked up via an antenna? I don't exactly understand how it works.
Will an external antenna help me pick up channels via CADTV / QAM better? I don't want to buy something that will not really help. How do I connect that to my TV? Would I have to disconnect the regular Coax cable?
Its regular cable, this question is about the HD CHANNELS that I DON'T pay for. Its about how to increase the quality for these channels.

The question is, what's the wall jack connected to? Does your apartment have cable? Does the apartment have a common antenna on the roof?

If it's cable, then you will need to talk to the cable company. They should be delivering a good quality signal to you.

If the apartment building has a common antenna, talk to the building management about making it work properly. If you are using an antenna, the quality will depend on how strong the signals are at your TV. Visit http://www.antennaweb.org for guidance. If you are more than about 5 miles from the transmitters, an indoor antenna ("rabbit ears") may not work well.
