HDTV OTA Reception & PVR (Pinnacle PCTV HD Pro Stick)? - pinnacle pctv pro serial number

It is a product that has received the digital signals, and you can OTA TV on your laptop / desktop.
I just wanted to know whether the product works, even if you live in downtown New York and are surrounded by skyscrapers. Someone said that the reception of digital signals OTA be difficult if you can live in an open field, but he saw thiis product in the stores. I asked someone who works there, but keeps missing opportunities. Ideas? Thank you in advance for your comments and suggestions.
