Holland Electronics 8-Way Cable TV Broadband Internet Signal Splitter
Holland Electronics
This GHS Series 1 GHz 8-way Splitter is State-of-the-art, designed and tested using the most current procedures assures success in hooking up Cable TV, TV Antenna, HDTV Sets, Broadband Internet modems and two way subscription Services with a Low intermodulation design and optimized return band prevents high cable modem signals from affecting forward band transmission. Therefore, the GHS-8 series digital splitter is ideal for present and future multimedia applications including video, telephony, and transmission sensitive digital signals such as QPSK and QAM data. New performance features have been incorporated to make both series compatible with the latest digital and return path requirements. Ideal for digital and cable modem applications with high surge resistance and unique plating for unmatched corrosion resistance to withstand harsh environments.
This is a great Splitter for Inside and Outside Installation of the Home or Office. Its Double Thick Plated Housing is Soldered Closed and Sealed from the Environment, as well as Transient and Spike Voltage Resistant. The Finish Doesn't change colors as much as the Chemically Treated Housings do when subjected to Weather. It will pass Forward and Return signals; making it perfect for Splitting Cable TV with High-Speed Internet Connection Signals. The Voltage Protection also makes it suitable for splitting HD TV Antenna Signals as well. The Flat "F" Connector ends means that the connection to the RG coaxial cable you use (RG-6 or RG-11) is solid, secure and doesn't slip or back off after tightened with appropriate force (most Coaxial Cable Manufacturers specify in inch/pounds). When making RG-6 or RG-11 cable connections outside, a weather boot covering and some sort of Silicone compound are highly recommended.
DownloadCoaxial Drop Cable Directional Couplers
RF Directional Couplers are like splitters in that they can feed two lines from one, or combine two signals into one cable or feed. The insertion and coupling loss is different however, when compared to a simple two way with an equal split of one half, or 3 dB. The Directional Coupler will "Tap Off" Some signal to feed a local TV or similar component and send the Majority "Thru" to continue on down the Line to Continue or Repeat this exercise over and over again. This type of Distribution occurs in "Loop Run" systems that essentially run one cable past each user in a "Loop", Tapping signal to feed each as it passes. This example is used in most Hotels and Motels as the cable runs up or down from floor to floor passing the next room above or below, using a Tap to "tap-off" signal to each room as it passes. In a more Domestic Situation, a coupler is handy to feed a device close to the origin of the signal (like where the Cable TV company attaches to the house outside) and send the majority through a relatively long run to feed other devices at the end. Cable TV Companies do this quite often in "Tapping-Off" signal to feed the Cable Modem. Another Situation would be that one device simply requires more than the other and both would be Accommodated using this Device. They are typically rated in dB as to the Loss incurred from "Input" to "Tap" leg, with the "Thru" Leg suffering comparatively less loss. The Higher the dB Tap value, the lower the "Thru" leg loss.
If you are adding several Directional Coupler Drop Taps to an existing Cable TV or Antenna feed, you may need to compensate for the loss that you are about to introduce. The gain of a Line Amplifier should be selected to zero out the loss that follows it. In other words, if you have fifty feet of cable and a two-way splitter, then a 10 db amplifier will be fine. Conversely, if you have an eight-way splitter and hundreds of feet of cable, you will need an amplifier with a higher gain. Just as in the case of a Pre-Amplifier, however, bigger is not always better.
