I've been working on and off on this for months now. situation: HDtivo hooked up to an old roof antenna that doesnt get a couple of HD locals, added a big UHF winguard antenna which gets strong signals for all the locals on the tv tuner but not on the HDTivo (even cases of not getting in one channel but getting another channel broadcast from the same tower).
-The wineguard is directly wired to the HDtivo
-attenuator did nothing but weaken all the signals the HDTivo saw
-Fm Trap did nothing
basically i cant get the local Fox and Pbs using the old roof antenna so i bought a new antenna. The new antenna hooked to the HDtivo sees the Fox station but not Pbs for some reason (they share a tower). It also looses other locals that the old antenna got in strongly. The wineguard hooked to my tv gets all the locals in strongly.
is there anything else i should try? could the OTA tuner in my box just be screwed? should i try combining the 2 antennas?
ps. all refernce to "HDTivo" is referring to the directv hd tivo (incase a non-directv one came out)
