Those transformers do not look like they are for any frequency near 10 MHz. 
I would take a guess that this is for UHF frequencies. Why don't you 
terminate 7 of the ports into 50 ohms and measure the loss from the main 
port to the 8th port. Do you have access to a signal generator and a RF 
voltmeter/spectrum analyzer/receiver/other way to measure RF?

Or feed in 10 MHz and look at the output with a scope. In any event, it will 
have a lot of loss, probably around 12 dB.

Regards,
Tom
