How do you combine antennas that point in different directions?
Combiners (which cost about $20) merge the two sets of signals into a single stream of TV. Using a combiner is as easy as plugging the coax cables from the two antennas into the combiner device and then using a third coax cable from the combiner to connect to the Tablo OTA DVR or TV. Easy peasy!
How do you stack two antennas?
There are five important things to do to make a good vertical stack. (1) Use identical antennas. (2) If you use coaxial cable, such as RG-59/U, you should also use a weather-proof 300-ohm to 75-ohm matching transformer mounted as close as possible to each antenna. (3) Use a hybrid type splitter.
Can two antennas interfere with each other?
Isolating antennas at different frequencies
Antennas that operate on different frequencies should be placed so that they will not interfere with each other. In antenna terms, they need to be electrically isolated from each other.
Can you use two directional antennas?
Adding a second antenna can increase the signal path coverage and give you a more consistent signal. To accomplish this you will need a combiner or coupler that can combine the two antennas together. I would recommend that you use two identical antennas. This will ensure a balanced signal path and coverage.
