![]() The most common source of TV signal pollution (AKA interference) today are 4G/LTE cellular signals, which has made LTE filters quite popular. Like your water supply, your Over-the-Air TV signals can sometimes be polluted by unwanted materials. Over-the-Air TV signal can ‘leak’ out of these openings, reducing signal strength. However, unlike a TV with a single tuner, your Tablo OTA DVR contains either 2 or 4 tuners which can result in some signal loss despite its built-in pre-amplifier.Īnd, just like you wouldn’t leave one of the openings on a garden hose splitter open, don’t forget to plug any unused coaxial ports on splitters or distribution amplifiers with a terminator. ![]() If your signal is already quite strong, you may be able to split your signal between two devices (like a Tablo DVR and a single TV) without the need for a distribution amplifier. So, if you’re experiencing trouble with reception, and you’ve never tried your antenna without its amplifier, try disconnecting it and run a new channel scan. If you plan to share your antenna’s signal between your Tablo and multiple TVs, or you have a particularly long run of coaxial cable (100+ feet) between your TV antenna and your Tablo, a distribution amplifier is a handy accessory.Īlong with the Over-the-Air signal, your TV antenna will also receive noise (AKA interference) and amplifiers – especially lower quality models - can boost both. Unlike regular TV signal splitters, distribution amplifiers are designed to mitigate signal loss when splitting the signal from a TV antenna between multiple devices. Some require an additional A/C adapter to power the device. These amplifiers are either built-in to the TV antenna or are an optional attachment that connects to the end of the coaxial connector of your antenna. There are two primary, types of OTA TV antenna amplifiers: in the morning or evening due to temperature inversion or bad weather) lose enough power disrupt viewing or hit the digital cliff, an amplifier may be a good option. If you have a channel that gets good reception most of the time but can occasionally ( i.e. TV Antenna amplifiers are the ‘power washers’ of Over-the-Air TV accessories.Īnd, while one might think that amplifiers are designed to help pull in signals that are too weak to get, amplifiers only boost the power of signals you DO receive, just like power washers increase the pressure of the water you already get from your tap. In the end, your goal is to get the water (OTA TV signal) to all the places you need it, without having too much or too little pressure (signal strength). Your water access and water pressure (OTA TV signal and OTA TV signal strength) are variable depending on how close you are to the water main ( OTA TV tower) and what gear you have in between the spigot ( antenna) and the place where you’re trying to access that water (your Tablo DVR or TV).įor example, you might use an extra long hose (coaxial cable) to reach the garden at the very back of your yard, or you might connect various tools to your hose like a power washer ( amplifier), splitter ( distribution amplifier), filter, or spray nozzle ( attenuator). Imagine your Over-the-Air TV infrastructure like a garden hose, and your OTA TV signal as water. ![]() Your Over-the-Air TV Signal Infrastructure If you’ve followed the best practices for installing your TV antenna, but one or two channels aren’t coming in as well as you’d like, or you want to split your antenna’s signal between multiple devices, you will want to investigate antenna accessories like amplifiers, filters, and attenuators. (If you haven’t checked out our guides to picking and placing your OTA TV antenna, check those out first.) It’s also one of the best times to install a new Over-the-Air TV antenna or tweak your antenna TV setup.
