Check ut www.antennaweb.org for antenna recommendations for your address. You have some choice for HD receivers (RCA Samsung etc) I believe there are some other forums dedicated to then, you could do some research there. You might also want to look at the HDTV-in-SFbay forum on yahoogroups.
You quest to receive KNTV-DT from SF is going to be a hit or miss solution. The STB can be any of the available boxes - they all work good. Everybody has their favorite. It comes down to if you want satellite capability or not. If you do then which service - Dish or DirecTV. The OTA antenna is a whole different story. You may want to start by asking for help from someone in your locale. Here in the south bay the reception problem is not the same as it is in SF. So the antenna that I use most likely won't work for you.
