Review on 🔌 Tycon Systems TP-DCDC-1224 - 12VDC to 24VDC Converter, 19W Max Output Power by Todd Atherton

I've heard of everyone successfully connecting Ubiquitys antennas to this 12V step converter, but I don't know how. The antennas come with a POE injector that has an AC power input at the top and two Ethernet POE/LAN ports at the bottom. When I connect the POE output of this device to the POE input of the Ubiquity ethernet injector, there is only one port left to the LAN to the antenna, and there is no return from the antenna output to the LAN. In other words, this device gets power but doesn't send a signal unless I do another ethernet boot back to the router. Any suggestions?
