RF splitters?

[AVRat]

Is there really any difference in RF splitters?

Yes, it maybe not stated in first two, but third one - CHANNEL PLUS 2532 is rated for bandwidth (Selection priority #1) and insertion loss (#2)

Would you buy speakers with correctly stated Freq response, THD, impedance and efficiency ? Nor you should get RF splitter which may or may not fit your needs.

Yes there are differences, and I generally prefer stuff made by regal.

Most good splitters will have the amount of attenuation for each leg labeled and the back will be sealed with a gasket or another acceptable material.

Cheap ones don’t state the amount of attenuation and have backs that are cheaply glued on.

Also depending on the application, you need to know if the splitter is bi-directional, which come into play if one of the legs is going to feed a modem or on-demand capable cable box.


Edit: I typed to slow and forgot about bandwidth
