I have two hdhomerun duals sitting on my network and a HVR 2250 dual tuner card in my HTPC/DVR. Each of these devices is connected to a different antenna pointed in different directions. Two of the antennas are in the attic, one is an unobtrusive 4 bay bolted to the side of the house.
I am using the MythTV DVR software running on the HTPC to receive the signals from these antennas. MythTV organizes channels by input device. So in this case there are 3 devices with 2 tuners each. When you create the input, you do a scan for each one and any channel that it can pick up is associated with this device. You can also manually add and delete channels from each input device. This is all transparent to the end user. When you select a channel from the front end interface, it simply picks the correct input (antenna) for that channel. It works the same way for recordings. If the channel can be received on more than one device, you can give priority to the selection and even distinguish that by liveTV vs recordings. It will pick the first available device based on this priority.
MythTV doesn't care what kind of input device it might be. It can work with cable TV set top boxes via firewire, other boxes using an IR blaster, satellite FTA cards, analog tuners, and even http live streaming channels.
It works really well as an electronic version of the old antenna rotator concept. Myth is also smart enough to know that signal might contain subchannels and can receive them simultaneously using just one tuner. So effectively, 6 tuners becomes 12. I have 3 TVs in the house using this system and they can all view LiveTV or any recorded show through this system. I can also use any networked PC and even my android phone as well. They all have access to the OTA Live TV and recorded TV.
I simply could not find a way to pick up all the Charlotte OTA stations reliably using one antenna. This was how I solved it. I can receive everything, including WHKY from their main tower and it's rock solid even in very bad weather.Edited by blackcat6 - 2/14/13 at 9:18am
