I bought two of these - the Channel Master and the Kenable to see how each one does. I have actually three antennas so whichever does the job and is least expensive I'll get a third. The first two are on the way.
My house has two cell towers - one a half a mile away and another on the other side of the house a mile away so I'm triangulated by these towers. But as someone indicated, it may not be just the towers but actual cell phone conversations in the area. One of the symptoms of cell phone interference is that these signals are actually quite strong and cause an amplifier to overload a tuner! That video I referred to above shows on a scope how much stronger these signals are than the normal UHF ones. I noticed that one of my preamps was showing overload via a flashing indicator at the time my signal started to flutter. Normally NONE of my TV signals come even close to overload as I'm 30 miles away from the TV broadcast towers.
How ubiquitous have cell phones become? Teenagers and parents now text message each other INSIDE the home. Heck, my wife calls me on my cell when I'm downstairs in the basement - why holler! Another YouTube video shows the effects of a nearby cell phone call on a set top box. Even though a Tablo filters out LTE, the preamps BEFORE it don't. Channel Master and Antennas Direct have now started to include LTE filtering WITHIN a preamp. Televes and Antop have now embedded LTE filters within antennas.
LTE interference not only pixelates a picture but can knock out entire channels. People have had lost channels restored when inserting a filter.
However I'm also checking my home appliances since these can also be a source of interference - such as a thermostat. Older devices can become a source of electromagnetic interference as their connections wear out.
The question is if LTE interference is a cause of disruption, how many other Tablo problems are being caused by this phenomenon? We tend to hilight Wifi, hard disk errors and antenna performance but should LTE interference also be mentioned with respect to interrupted programming?
