ASKA TGV-21G 2-Way Cable TV, Antenna and Broadband Internet 1GHz Coax Splitter
ASKA
This TGV Series 1 GHz 2-way Splitter with Vertical "F" Ports 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.
Features an Equal Loss Design with Vertical input and outputs allow close mounting in lock boxes for easy access of cable connections. Nickel treated zinc alloy housing for best corrosion protection Tongue & Groove housing for better RFI shielding. Printed circuit board ensures consistent RF performance and high port to port isolation. F-ports with machine threaded spaced 1 inch center to center to accommodate security sleeve and tools with heavy duty ground blocks ensures proper grounding.
This is another one of those splitters you would find or use inside of those steel lock-boxes on the side of an Apartment complex, in the little gray box or upstairs in the Attic. It features Vertical Port "F" connections. Its typically used inside of these little boxes because it's easier to connect/disconnect the cables when all the "F" connection Ports are facing in the same direction. So when you are mounting a 3-way splitter in a tight space without a lot of room around it for the RG-6 Coaxial Cable to make connection, this is the one you want! It will pass Forward and Return signals; making it perfect for Splitting Cable TV with High-Speed Internet Connection Signals.
Coaxial 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.
