No. The ports on the Channel Master Ultra Mini 8 (CM3418) are not power passing. However, an option would be to use a Ultra Mini 1 (CM3410) one port distribution amplifier, and a short cable to a power passing 8-way splitter. This would have the same gain as using a Ultra Mini 8 (CM3418) since it has an internal 8-way splitter after the amplifier.
Please see the diagrams link attached below to help you understand how to connect a preamp/distribution amp in your antenna system.
