This is an excellent product when used PROPERLY -- and as intended. This is a SPLITTER, which means that BOTH of the "OUT" terminals should be connected to cables of the SAME, or nearly the SAME Length in order for your equipment to receive an equal share of the signal. In other words -- the RCA splitter has 1 "IN" and 2 "OUT" terminals -- and the cables attached to the terminals must be the SAME or nearly the SAME length so that the signal loss in each cable run will be the same for both components. Example: If you have one cable coming off the Splitter that's 60 feet long but the other one is only 6 feet long, they'll be way out of "balance", and certain equipment (such as a cable modem) will not function the same on either length of cable. Internet connection speeds are very sensitive to signal imbalance, so it's important to keep your cable modem on the shortest possible cable run, and NEVER on the "long side" of a junction !! Under those circumstances, a SPLITTER is the WRONG CHOICE -- and a "TAP" must be used !! A "TAP" looks a lot like a SPLITTER, but works differently -- the TAP has 1 "IN" and 1 "OUT" terminal, with the 3rd terminal "unmarked". -- With a TAP, the longer 60-foot run would be connected to the "OUT" terminal, and the shorter 6-foot run would go to the "unmarked" terminal. Note that the DH24SP is a "2-way" splitter, which means that the high-frequency signal can pass freely in BOTH directions, which is critical for high-speed internet's need for bi-directional, hi-speed transfer of data "packets" to and from your server/tester/ISP. Some reviewers have claimed that a cheapo splitter from the dollar store is "just as good" -- but that's just crazy talk !! And those gold-plated ones from "the shack" are NOT APPROVED by COX Cable, either !! I thought they were jackin' me around, but the COX Tech replaced my "golden" splitter with a SV2G 5-1000 MHz splitter and my internet connection speeds improved quite a bit !! Anyways, if you need a SPLITTER for high bandwidth applications, such as Satellite, Cable Internet, Digital Cable, or HDTV -- this is it !! Just remember to keep your cables as close to the same length as possible, and if you CAN'T, get a TAP for that long run !!! One other thing -- for absolute best performance and a strong, steady signal, place your Modem and your Wireless Router about 4 feet apart to prevent radio frequency interference. Electrical interference of any kind drives Wireless Routers crazy, which is why I use and recommend Category 7 (double-shielded) Ethernet cables !! The RCA (Audiovox) DH24SP gave a noticable improvement in the picture quality of our 52" Samsung LCD HDTV and to the 20" Standard TV on the other leg. It replaced an SV2 Splitter @5-1000 Hz. and -3 db drop per leg. Great product when used as intended, and well worth the money - especially since Amazon.com cut the price IN HALF of what I paid here just a few weeks ago !! The most important thing to remember is that this is NOT a signal BOOSTER, and it CANNOT make a weak signal stronger !! What it WILL do is divide a high-frequency signal into 2 separate but equal parts by using intelligent circuitry combined with quality components and excellent workmanship. The Bi-Directional capability MAY improve your computer's UPLOAD speeds, but that will depend on other factors. My own personal install (outdoors) yielded an average Upload Speed increase of about 275 % over the old ISP-provided splitter -- (it wasn't bi-directional)
UPDATE: 21 January, 2015 The RCA 2.4 GHz splitter has been going strong for four (4) years now, delivering internet speeds as high as 131 Mbps Download, and 30 Mbps Upload (Top 12% of the world), and excellent audio-video quality from Samsung 52-inch HDTV. Thanks to Amazon Customer Frostarix, I was made aware that an upgraded (3.0 GHz) model is now available from RCA-Audiovox. Based on the excellent service life and performance of the 2.4 GHz model, I would highly recommend the newer model to any and all who demand the absolute best performance from their equipment. Don't be fooled into buying the cheaper splitters, thinking that they are "just as good" -- or that they are "good enough" -- or that they are "a best seller" -- because there is no substitute for the economy of quality performance !!
