We can use the coax splitter cables in the video transmissions systems to branch off a single video feed to multiple sections. This is very convenient as it enables you to switch between channels coming from either of the antennas.
Two antennas can be hooked using a splitter. But both cables connecting the splitters and the antennas should be exactly of the same length and type. Stacking two antennas increases the range of channels and frequencies you receive.
How to Combine Two Antennas Using a Coax Splitter Cable
Stacking antennas can be done either as vertical (antennas combined on the same mast) or horizontal (antennas are combined adjacently) stacking.
You need to keep the combined antennas about 2 to 4 feet apart (one wavelength). It is because the antennas can generate slight interference. (1)
What you Need to Stack Two Antennas
- Two coax cables coming from the TV antennas
- One coax cable extending from the splitter
- A television-set
- A second antenna
- Twist locks for securing the stacked containers
Steps to Combine Two Antennas Using a Coax Splitter
- Identify a strategic place to set up your second antenna. Make sure it is at a considerable distance from the first one. At least 2 to 4 feet apart.
- Erect your second antenna.
- Now connect the second antenna to the TV.
- Proceed and attach the two coaxial cables to the splitter or a signal combiner.
- Connect the third coaxial cable extending from the splitter to your television-set.
- The last step is to ground your second antennae in weatherproof parts. (2)
Useful Facts and Benefits of Combining Two Antennas
- Stacking two or more antennas increases the range of channels and frequencies.
- Stacking antennas enables you to receive channels from the stations in other directions. It is because the second antenna can get stations that are outside your first antenna’s reception range.
- Combining antennas enables you to receive channels that are on another frequency band. Most antennas of modern TVs are dual UHF/VHF bands with the exception of a few. The second antenna picks up the frequencies which the first one cannot.
- Stacking antennas increases the total antenna gain by combining signals that are coming from multiple antennas. It raises the reception quality. However, this is a challenging concept to implement.
- You can use a reverse antenna splitter to stack signals from several antennas. Splitters work well if the antennas have the same frequency band. However, if your antennas have different UHF/VHF bands, use a diplexer instead.
- You should make sure both antenna coaxials have the same length and are of the same type. This will prevent phase issues.
- You may cement it with an amplifier to boost your experience.
