Original post says a "SILVER SENSOR" with a 2 way splitter. I agree with your post 100%. These people that complain and have no idea what they are doing. Come on a marginal signal source "INDOOR ANTENNA" combined with a split signal that is going to be split again internally? What do they expect miracles. In his case he needs a distribution amp between the antenna and splitter both TV and AM21 should improve.texasbrit said:FYI The AM21 tuner is much better than the HR20 tuner.
One thing to remember is that the AM21 has two tuners driven by an internal splitter and so each tuner is only seeing one half of the signal, or in your case one quarter of the original signal since you are already splitting the signal. If your signals are already marginal it is quite possible for the TV tuner to see stations the AM21 won't. You will probably find that if you use a pre-amp at the antenna (which one are you using, by the way?) or an inline amp/distribution amplifier the AM21 might receive the stations fine.
As posted earlier in this thread that is because the HR20's and AM21's do not have the ability to scan for channels. Of course you're going to get more channels on your TV because it can scan.ansky said:I get about twice as many channels with my TV tuner than with the HR20.
FWIW, I get similar bit-error rates (aka signal strength) with the AM21 and the HR20's built-in OTA tuner. I've got a pre-amplified outdoor 8-bay UHF antenna feeding both, though, and I'm less than 30 miles from the source, the Empire State Bldg in NYC. My bit-error rates are usually in the mid-90's, often touching 100.Grentz said:The AM21 tuner is quite good. It uses good ATI chips that are pretty darn sensitive. There are plenty of tuners out there that are much much worse.
I am 35-40 miles out, have to use quite a large antenna, and have an amp, and have no issues. I would look into a better antenna and/or amp and you should have no issues at all.
Yes, I didn't read the post carefully. You are right, trying to split the signal from a silver sensor is unreasonable, it's a good antenna but not that good. And a four-way split (which is essentially what you have with the AM21) is a real problem.boba said:Original post says a "SILVER SENSOR" with a 2 way splitter. I agree with your post 100%.

I'm not talking about scanning. I'm talking about directly tuning a channel. For example if I type in channel 50-1 on my HR20 I get 'Searching for Signal'. But if I type 50-1 on my TV it comes in fine.RunnerFL said:As posted earlier in this thread that is because the HR20's and AM21's do not have the ability to scan for channels.

The HR20 has a weak tuner just like the H20-100.ansky said:I'm not talking about scanning. I'm talking about directly tuning a channel. For example if I type in channel 50-1 on my HR20 I get 'Searching for Signal'. But if I type 50-1 on my TV it comes in fine.
Please describe your hardware between the antenna and the receiver/TV set. Also - save the image of your channel lineup and settings via tvfool.com and attatch them here so we can give a more accurate estimation of your potential problems.ansky said:The HR20's tuner is no good either. I get about twice as many channels with my TV tuner than with the HR20.
