Works exactly as expected,
Verified Purchase(What's this?)
This review is from: RCA DH24SPF Two Way 3 Ghz Bi-Di Splitter (Electronics)
Signal quality of cable did not seem to be affected by using this.
Also used with Cable modem (30Mb down, 2Mb up) and noticed no degradation of quality, including ping times (7ms ping to various servers using speedtest.net).
Basically this did not affect my cable modem internet service, which is what I was really afraid of.
