Hi Both units put out DC to the antenna. With them “dc coupled” to each other and the antenna, you may see “antenna open” (low current) warnings. There are multiple solutions ranging from using DC loaded couplers (HP/Symmetricom) or simply tacking a resistive load on a multi-port splitter (Mini-Circuits). If cost is an issue and you can find a 3 or 4 port 2 GHz satellite dish splitter, those also work.
