Signal Vision SV-A15PRS-I-M Broadband Digital Cable TV Modem HSI 1 GHz 15 dB Gain Amplifier
This CommScope / Signal Vision Product is a Quality Indoor/Outdoor 2-way Services 15 dB Gain Amplifier and is used by Comcast and other Cable TV companies in Installations of HD and HSI. Powered by a 12 VDC 200 mA supply, It is 2-way Services capable for PPV Programs and High Speed Internet connection to the Broadband Cable Modem. Install this Amplifier Inside or Out, comes with a Power inserter and Power Supply, each featuring "F" Port connections to facilitate multiple installation options using the same RG-6 cable used in the Cable TV Install (See "Install Guide" below). Install this Amplifier before the splitter that feeds to multiple TV set locations as to negate the loss of signal.

Too many times, you're stuck trying to fix the no man's land between your Home wiring, and the Cable TV Company Feed from the Pole or Pedestal. Old Installation cable and years of Up-Grades, Additional Outlets, Bandwidth Changes, Modems and High Definition leaves you with a distribution system beyond what was originally envisioned. The Cable TV Company will be happy to Charge you to go through and Re-Install your Home, or you can do it yourself! With HD Digital Signals, the Signal Level is actually lower than the analog, and with increased Channel Capacity, not enough is there to feed your Home. Check Your Picture quality where the Cable TV feed enters your Home, if it's good there, you can replace connectors, cable and splitters to bring your installation up to the newest specifications. If you are feeding numerous TV sets, Cable Modem and/or long Distances, use this Amplifier before the Splitter to maintain Signal Quality. What's nice about an Indoor/Outdoor In-Line amplifier is you can put it in anywhere, and move it to anywhere else later! Just use a Barrel Connector (F-81) or short jumper to reconnect the cables together in absence of the Amplifier you removed. If the Picture quality is Poor at the Feed point of your House (the Cable Company usually has a gray box used as a Demarcation Point for this Purpose), call your Cable TV Technician and Demonstrate to him your issues, so he can effect repair.

RG Coaxial Amplifiers


All of these Amplifiers will Pass HDTV, DTV and Analog Signals. Those that have a Specific Band-Pass of up to at least 890 MHz are good for VHF/UHF and FM also... Making Them Suitable for Home use of Off-Air Antenna Television Carriage. Those Amplifiers with Band-Pass Specific to 2150 MHz means that they Boost Satellite Signals... If these same Amplifiers have a Start Frequency of between 5 and 54 MHz, they are Wide-Band and Carry Cable TV or Off-Air in Addition to the Satellite Signals. If the Star Frequency is around 950 MHz, then they are Solely for Satellite Carriage.

Amplifiers- Should be utilized for these two reasons:

To increase already adequate signal as to pre-emphasize the level to balance out losses after the amplifier such as splitters and cable in the distribution system on its way to various TVs in the house, and

To maintain Signal level to noise at the origin (your antenna) so that low signal levels from far away stations are not lost in a longer than average cable run to the location in the house where the signals would be further distributed to the TVs desired.

Amplifiers and Pre-Amplifiers come with various gain numbers. Old Analog signals needed a high Carrier to Noise to get a high Signal to Noise Ratio of the Picture on your TV set, it was a one to one relationship and more was sometimes better. Digital Signals are lower in amplitude in comparison to Analog (a benefit) and that commensurately, the threshold at the TV is lower for a perfectly good picture. Very little in between, you either get a good picture or you don´t. Snow in the old analog pictures has been replaced by "Tiling" or little blocks within the picture not keeping up with the scene changes in today´s Digital TV viewing. Tiling is therefore today´s Digital Snow. It means (more often than not) that you are not far enough above the threshold of signal level into your TV to prevent little hiccups, drop-outs and interferences in signal from interrupting the Stream of Data. Remember that lots of things can happen from the Station on the way to your TV set!

Pre-Amplifiers are mistakenly used with the rational that it will bring in Stations that weren´t there before... It won´t, and what´s worse, using the same antenna and pre-amp with FM and TV stations close by (20-30 miles) may overdrive the amp and actually impede your ability to provide goods signals to you TVs. If you desire to use a pre-amplifier, don´t use a high gain when you have local stations, get one with a FM trap to keep FM radio stations from over-driving the amp and remember that today´s Digital Signals don´t need to be high to get a picture. Some Pre-amps come Band Selective as well, realizing that the difference in antenna UHF/VHF gain means that one band needs to be amplified as opposed to the other.

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.
