Looks like a Simple reception situation , with 1 antenna aimed in 1 direction.
So that I make a recommendation.
What is the Make and Model number of the antenna that is up on the tower??
Does it look like a old antenna that has been up for a long time and is old and beat up.
If not know the make and model number , then what antenna looks the most like the antenna.
