Interestingly by the math, and because of inherent error correction, all else equal digital is receivable further than analog in “perfect” condition.īut human eyeballs and brains do a great job as DSP filters and we’ve all watched a slightly noisy image before in the analog days, or even a horrible one, and as long as the audio isn’t overly affected we fill in the missing data or ignore it. Scan and rescan is the word of the month - one market near me just shut off their 'pre-repack' digital transmitters this week. The amplified splitter makes a little difference on the longer runs (and makes up for the splitter/power divider), though it is easy enough to overload the amplifier if one is not careful. The longley-rice projections show that the signals should be fine where I am.Īside from the one flaky channel, the other channels are rock solid & strong.

I am 12 miles, line of sight, to the TV towers, but lack full fresnel clearance on part of the path (not counting the trees). The digital signals can be a bit more fragile to 'unintentionally radiating' stuff in the house - that becomes particularly true if your antenna coax has badly installed connectors and the like. With the exception of a couple of public stations, all the other local stations transmitters are within a mile or so of each other. I found that there was LTE interference (installed an LTE filter), and am still getting some other interference affecting one of the RF channels (I can see something moving around on a spectrum analyzer but haven't tracked it down - yet) that's enough to cause occasional dropouts on that channel. I've got an older Channel Master 4228 roof antenna, about 75' of coax, an amplified splitter, and then coax feeds to each set.

Great if an indoor antenna works for you - just don't fall for the hype. Hence, it may be necessary to go with an outdoor antenna. Digital signals tend to be more 'fragile' than the older analog signals.
