Hopefully my photo comes through OK.
Thanks for the excellent photo; it came through fine.

rickbb is correct; sometimes it works, sometimes not.

The two antenna systems aimed in different directions CAN be combined with a splitter in reverse.

It doesn't always work, because when the same signals from each antenna reach the combining point they will interfere with each other if they are not in phase (arrive at the same instant). If you don't have all the signals after combining that you had when the antennas were separate, then combining doesn't work for you.

If it doesn't, there are a few alternatives.

You can use an A/B switch to select which antenna you want to use. If your TV isn't able to add a channel after scan, you will need to rescan after changing direction.

You can connect the main antenna to the TV antenna input, and connect the second antenna to an external tuner with its output connected to the aux input of the TV. It's my favorite solution.
