I currently have the Stealth Antenna (Channel Master 3010) in my attic running with a pre-amp. I know it is not multi-directional. I live in Fort Lauderdale and have stations directly to the south (Miami) and to the north (West Palm Beach). I'd like to improve my overall reception. Does anyone have a Channel master 4228 in their attic? If so, how much signal strength are you losing and how are you running it to your TiVo?
