I have a rca flat antenna (1450 BR) that I picked up at walmart a few years ago to use when my two tuner DVR from cable was recording stuff. I would just switch over to antenna mode and watch the national channels. Now with that said,I have gotten a HR-44 and 3/C41 set up recently and I pulled out the old antenna and ran a scan and it picked up quite a bit of regular and sub channels. There many channels that showed up that I wish D* just had in my normal local set up guide such as Telemundo HD,Estrella TV,RTV and Antenna TV rather than monkeying around with an external antenna. I would like to get a am21 tuner so I can pick up said channels and mix them in with the normal D* guide but I dont really trust the rca antenna even though it picks up quite a few channels with good strength. I'am just worried that I will be recording stuff one day and I would get a bunch of glitching and pixelating due to the antenna. Anyway ,can anyone recommend a very reliable indoor antenna that works extremely well with the am21 or will the old rca make due?
