The 10 Best Antenna Splitters
This wiki has been updated 3 times since it was first published in October of 2019. People continue to want certain types of live programming despite a mass migration to streaming platforms, and over-the-air HDTV provides a great solution. Whether you have a roof-mounted aerial or just want to avoid purchasing multiple antennas, a splitter is a useful accessory that will allow you to enjoy these broadcasts on all of your televisions while minimizing cost and clutter.

All of the splitters on our list are useful for certain situations, but there are a few key considerations you should make to figure out which one is right for you.
For instance, the two factors which determine whether or not you will need a splitter with a built in amplifier are the strength of your reception and the length of cable you are trying to send your signal over. If you're lucky enough to have very strong reception and don't need to run cables too far, very affordable options like the GE 2 Way, Channel Plus 2532, or Uxcell 3 Way Adapter might be just enough. These cheaper options, the latter of which isn't even technically a splitter do to its lack of internal circuitry, typically cause a higher loss of strength, but that shouldn't be a problem if you're dealing with a great signal that's able to withstand such degradation.
If your signal is just decent or you don't mind spending a few more dollars for a higher quality product, you should check out the slightly more expensive passive models like the BAMF Coax Cable Splitter or GE Digital 2 Way. These units can't avoid signal loss altogether since some amount is inevitable to any joint between coaxial cables, but they feature a drop of only 3.5 decibels, which is just about the littlest amount available among these types of units. These higher-end passive splitters also generally have a better build quality, greater corrosion resistance, and advanced features like power-pass, which allows easier integration with separate amplifiers if you find that such a device is necessary.
Of course, the only thing more convenient than an amplifier paired with a splitter is a splitter with a built in amplifier. A common misconception is that these units can make your antenna receive more channels, but that's not quite right. What they can do is amplify the quality of a signal that was already present, which will potentially increase the quality and consistency of the image on your TV screen, and prevent large amounts of signal degradation over long lines of cable. For instance, let's say that you live in a multi-story house and you have an antenna mounted on your roof, but both of your TVs are on the first floor. If the cables take a long circuitous journey through your home, something like the Channel Master Ultra Mini 2 might be the perfect tool for preserving your signal. This can be tricky to get right sometimes since over-amplification is possible and causes an equally undesirable effect. If you're in a situation where one television is very close to the antenna but the other is not and you're worried about over or under-amplification, keep in mind that it is possible to pair a passive splitter with a single-line amplifier between it and the more distant TV.
It's not at all uncommon for households to have more than 2 TVs, and while several of the models on our list are available in configurations with more outputs, we've showcased the Neoteck 6-Way, Antronix 2004H-A, and Antronix Amplifier. The latter is considerably more expensive due to the integration of powered amplification circuitry, but this is a desirable quality given the consequences of each added output. Insertion loss stacks exponentially, and the internal circuitry of these units is actually quite similarly to the effect of daisy chaining multiple 2-way splitters. In general though, purpose built splitters with many ports generally perform a bit better than the equivalent of linked 2-way splitters. For instance, a pair of 2-way splitters with 3.5 decibel insertion loss linked together leaves you with one -3.5 db output and two -7 db outputs, whereas the Antronix 2004H-A provides 4 outputs with only 7 decibels of loss. It's not a perfect science, and it may be that stacking 2-way splitters or putting amplifiers on certain lines of a 6-way splitter will be best for you.
All of the models on our list are compatible with RG6 and RG59 coaxial cables, and should work just fine with any television or dedicated tuner capable of decoding digital TV signals. All of our selections should also remain functional after the switch to the even higher quality ATSC 3.0 broadcast standard. Unlimited 4K programming on every TV in the house for around $50 or less? It's almost too good to be true.
