Beside this, can you split a coax cable?

Coaxial cables, which is what cable providers use in your house, can carry a lot of bandwidth and are able to carry TV and Internet. So you can easily split the signal for both purposes. A cable splitter will allow you to send the same signal to several devices.

Furthermore, how many splitters can you put on a cable line? Use a splitter with as few connections as possible (two way splitters will typically have the least signal loss). Try not to daisy chain splitters (splitter attached to a splitter). If you need more ports, a four-way splitter is better than 3 two-way splitters. I've seen splitters with as many as 16 ports.

Considering this, is splitting cable illegal?

In the US there is a law that forbids Cable companies from charging per outlet for services. There is one charge no matter how many rooms, TVs, outlets it's being used. Now they can charge for them to install the outlets, for rented equipment, repair.

Can I split cable to TV and modem?

If your business gets cable TV and high-speed internet access from the same company using the same line, you can use a coaxial splitter to connect your internet router and one or more cable boxes to the internet. You can also consider using wireless digital alternatives to traditional cable TV to reduce wires.
