10 MHz reference distribution (daisy chaining vs. BNC tees vs something else)
For a 10 MHz signal the wavelength is 30 meter so when the cable length approaches that 30 meter you might run into issues if you just split the cable using a BNC-T.

If you stay far below that 30 meters then this is generally not an issue.

If there is the possibility of daisy-chaining then I would use that as the first choice. Do note that if one of the devices in the chain is off or not receiving mains power, the devices further up the chain might not receive the clock.

I would limit the amount of splitting the signal using tees to a minimum.

Sure you can use a combination of daisy-chaining and splitting.

From practical experience, if the number of devices is limited then it does not really matter much what you do. They are still able to use the clock signal whatever the way you choose to distribute the clock.
