Model WM2PD-20-530M-N by Werbel Microwave is a 2-way splitter and combiner that covers 20 MHz to 530 MHz, HF, VHF and low UHF.   It handles 50 watts input power as a splitter or 5 watts per port as a combiner.  Note that because of the transformer-based design it does not pass DC to the output.  Made in USA with lead free solder, but 63/37 is available on special request for military customers.
