Long time member, seldom poster. Been in and out of the HT world for quite a while. I have a question regarding an LCD Purchase I am about to make for my folks. They are looking for a 19" LCD (this one sepcifically ... Buy the Sharp 19" LCD HDTV and other LCD & Plasma TVs at circuitcity.com ) There will be no cable box or satellite hooked up to the set as it will be used in the kitchen. Question being is will this set need some type of external antenna to pull in a signal? An antenna to pull an over the air HD signal? Or is everything built into these sets and are plug and play??? Thanks in advance!
