Standalone LTE Filter Now Available!

You asked, we answered.

When we rolled out our line of Televes antennas with LTE filtering, the most common question we got back was “how can I add LTE filtering to the antenna I already have?” Certainly you could add one of Televes’ amplifiers, but if you’re doing just fine without an amplifier now, you probably don’t want to add one just to get LTE filtering. Luckily, we now have a solution.

Behold the Channel Master CM-3201 LTE Filter. Put this in line between your antenna and TV, and poof… LTE signal interference is a thing of the past. This beefy, industrial-grade filter will block all LTE signals; in fact it will block nearly all broadcasts outside the TV bands. If you were getting interference from nearby cell towers because your old antenna was actually receiving cell signals, this is really what you need.

You see, the 700MHz spectrum now used for cell signals used to be used for UHF television. Your older antenna — and even some newer antennas — receive these frequencies well, because they’re designed to. LTE signals come from a lot closer than TV broadcasts, since cell towers are usually less than a mile away. So, they tend to be stronger. TV signals start with massively powerful transmitters, but that power slips away as you get further from the towers. Closer cell tower signals can be quite a bit stronger than distant TV signals.

With an LTE filter in place, those signals don’t make it to your TV, and that’s important. Some TV tuners will try to compensate for weak signals on a channel-by-channel basis and some won’t. This means that if you have a strong cell signal coming in on (what used to be) channel 52, your TV will adjust so all the signals appear less powerful. This is called auto gain control and it’s a feature of pretty much every digital receiver, whether it’s in a TV, cell booster, satellite box or anything else designed to pickup broadcasts. So, simply put, a strong LTE signal might be great for your phone but when it comes to TV, it can ruin your entire day.

I’m the first to admit that this filter is a little pricey. For not much more, you can get a whole new antenna from the excellent Televes line. But let’s be honest here. If you were interested in a new antenna you would have bought one, or at least you would be considering buying one. Maybe you don’t want to get up on the roof or maybe you just like the antenna you have. That’s fine, and now you can like it even more by adding this small part. You don’t even have to get up on the roof… add it anywhere between antenna and TV.

If you have multiple TVs, add it before the splitter. You don’t need a separate filter for each TV, making this an even better value.

So, if you’re concerned at all about LTE interference on your TV (and you should be) you certainly could change out your antenna. But, if you don’t want to do that, the next best thing is to add one of these filters. Get one today!
