HOLLAND HR-FPI 2 GHz Satellite and Antenna TV DC Power Inserter
This Indoor/Outdoor Power Inserter passes 15-2150 MHz (2.2 GHz) Wideband Satellite and/or Off-Air TV Antenna and Cable TV frequencies, inserts the DC voltage from an external supply (up to 35 VDC @ 1 Amp) for powering an In-Line Amplifier or LNB(F) farther upstream on the same coaxial cable. One Port Power Passive (passes DC Voltage in one Diection only). All connections in and out of this Inserter are made by RG coaxial cable "F" connectors, allowing for an outside installation. The actual Power Supply (not included) is usually plugged in on the inside of the premise, with a segment or RG59 or RG6 running from inside to out, connecting the two for this purpose. Grounding Block Attached, series uses Solder Back Case for 130 dB RF shielding. Holland's high performance passives are designed for distribution of digital satellite signals in applications where signal integrity is critical. The HRS and HR VS Series splitters utilize diode protected circuitry to prevent DC backfeeding.
When Splitting the High Frequencies of Satellite TV Services to feed multiple Receivers, the Loss associated with the splitter may need to be compensated for with the use of an In-Line Satellite TV Drop Amplifier (Signal Booster) specific to this purpose and Frequency Range. Consider the need and review the "Satellite TV Amplifier" category for selection. Most of these Satellite In-Line Amplifiers are line powered from the Satellite Receiver and will not, under most circumstances, require any externally coupled supply that this is intended to couple. If the receiver doesn't inject DC power for use by LNB(F)'s, or the segment of cable you need to amplify doesn't have DC Voltage on the line at that point, and you need to install an In-Line Amplifier there, this is the means to get power on that line!
This Power Inserter will pass Frequencies also associated with Cable TV and TV Antenna use. TV Antenna Pre-Amps usually include a Power Supply and Inserter, if you need an Inserter for this purpose, this one will do... Most In-Line Cable TV amplifiers also come with the aforementioned accessories, but if you are missing them, this Inserter will also fit the Bill...
Also, if you need to block the DC voltage from passing on either side of the Amplifier, use the VBC (Voltage Blocking Coupler, separate item) to block the DC voltage from passing to other devices and prevent damaging them!
Commensurate with Coaxial Cable TV Antenna and Satellite TV Power Inserter Installation, you want to Ground your Cable TV or HDTV Antenna Coaxial Cable System Outside before bringing the TV Cable Inside. This way, Lightning Strikes and Power Surges have an opportunity to arrest before reaching your Satellite Receiver and TV Set(s). The Integral Grounding Block designed onto most Outdoor Use Compatible Satellite Signal Splitters and Inserters we sell will effectively convey this unwanted Electrical Energy to a Ground Rod via a Copper Ground Wire that you Install (not included). Consult your Local Building Code and NEC for guidance to Properly Grounding your HD TV Antenna, Satellite TV, Cable TV, WI-FI, Wireless Internet, Business Band, CB or Amateur Radio Antenna Installation.
DownloadAmplifiers
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.
About the Numbers
Amplifiers and Preamplifiers 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.
