    Greetings –

    I am writing to ask what is hopefully straight forward question that has been bothering me for a while now.

    For several years now, I have had an over the air antenna on my roof a little ways away from a Dish TV antenna. The OTA antenna was hooked into wiring within the house’s attic and throughout the house so that the OTA feed can go to any TV that is also hooked into the DISH network. (I believe that we had the technician end up using the DISH satellite wiring and had splitters or something to switch between OTA and satellite. (I cannot remember the details).

    My question is this:

    One or two of my TVs receives far fewer OTA channels than the others. I would have thought that they should all receive the same channels (no more, no less) since the feed is coming from one antenna.

    Any thoughts on why this is so?

    It could be several things. The TV receiving fewer channels could be father way and the cable runs are longer. It might require a powered splitter to boost the signal. This would allow the tv to have a stronger signal. The other issue I have seen, not all tuners are built alike. Depending on the television manufacturer, some tuners work better than others. I have two televisions both using the same antenna each TV has different manufacturers. One tv tuner works better than the other. You could try swapping TVs and recan. See if it makes a difference. Then you could determine if it’s the tuner or if you need a powered splitter.

Improve Signal Interference With The Channel Master LTE Filter

Unfortunately, signal interference has become more common with people using an over the air antenna. The popularity of smartphones has increased the amount of wireless interference. Cell towers are operating very close to OTA signal frequencies. This can cause pixelation and dropped signals to your OTA television signal. One way to eliminate this problem is to add a Channel Master LTE Filter. An LTE filter will improve your OTA signal by filtering out LTE, 5G, 4G, and 3G mobile interference. The installation is as simple as screwing in the filter between your antenna and the amplifier. Antenna Interference Before you add an LTE filter make sure you know where the interference is coming from. In many cases, it can be [...]
