A few days ago, I purchased a UV combiner made by a lactic acid bacteria teacher to use with a satellite. I am not using two antennas connected to a single duplexer; instead, I am using the U7V4 eight-element Yagi antenna (paired with two separate duplexers) that was recommended by Jyr. Today, I tested it on SO-50, and it performed exceptionally well, so I wanted to share this experience as a recommendation.
