I purchased a TIVO Bolt and setup an antenna and now I get 89 channels total. The local channels I care about are ABC, NBC, CBS, FOX and CW. I notice that when I check the signal strength they all show a signal strength of 72 from the Bolt, but when I test it from a TV containing a turner (tried 4 different units) the reading are all much higher 86 to 95, I read a post saying that this is as good as it's going to get, but when I talk to a support person from TIVO, I'm told a different story. They are saying that there is nothing in the Bolt to limit the signal strength to 72, it should be able to go much higher. My question , is anyone getting a higher firm OTA signal strength above 72 from the Bolt?
