ADDING A PREAMP TO AN ANTENNA SYSTEM  HAS THE SAME AFFECT ON YOUR TV RECEPTION AS WOULD INSTALLING AN ANTENNA UP TO 16 TIMES BIGGER

CM SPARTAN 3 MAST MOUNTED PREAMPS ARE THE MOST POPULAR PREAMPS IN THE USA. ALL MODELS HAVE 16DB GAIN ON VHF AND 23DB GAIN ON UHF.

All pre-amps have a power supply that plugs into an AC outlet inside the house that lowers the voltage and sends it up the coax to power the amplifier which is mounted up near the antenna. The benefit is that you get amplification before any line loss or noise and you don't have to run 117 AC up to your roof. NOTE:  Don't install a regular splitter between the power supply and the pre-amp or you will short circuit the system and it won't work. You can install a special splitter that is power passive on only one port. Or put a DC Block on the outputs  that don't run to the power supply. Also you can't put any type of matching transformers between the power supply and the pre-amp.

SPARTAN 3 Mast Mounted Preamplifiers

[Image]

The industry standard preamplifiers for over 20 years are now completely redesigned and updated.  Performance is better than ever before and all the features you require are included.  The industry standard 0064 DSB features a single 300 ohm VHF/UHF input and a single 75 ohm output.  Variations are available for applications requiring separate VHF and UHF inputs; 75 ohm inputs; VHF only models and models with active UHF and passive VHF passbands.

Models 0065 DSB and 0265 DSB are not supplied with a power supply.  They have been designed for optimized performance with a supply voltage of +12 to +22 VDC from a satellite receiver.  This power is normally passed to the preamplifier via a 40121FD (for a one output LNB) or 40321FD (for a twin LNB and two outputs) which diplex (combine) the VHF/UHF signals on to the same cable as the satellite signals.

MATV MAST MOUNTED PREAMPLIFIERS TITAN 2

MATV MAST MOUNTED PREAMPLIFIERS TiTAN

The Titan range of mast mounted amplifiers has been completely reengineered and updated. These amplifiers represent the ultimate in preamplifier performance. They are designed for use as an ultra low noise, ultra high gain preamplifier for deepest fringe applications and MATV headend applications. Their very high signal handling also makes them suitable for use as a mast mounted, ultra low noise distribution amplifier for use in small MATV systems. All models feature 75 Ohm input and output connections in line with modern headend engineering practice. Two models are available.


CM-7777 TITAN 2 Antenna Preamplifier - High GainSold Out Use Winegard AP8275


The Channel Master television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This antenna preamplifier is a high gain, low noise preamplifier used for weak signal areas to allow a weak signal that is present at the antenna to be amplified to a viewable strength. This TV antenna preamplifier works best for persons in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal areas our medium gain preamplifier, the CM 7778 is a better choice. Preamplifiers are also used if you anticipate distributing your signal with a digital splitter to multiple outlets throughout your house as splitters reduce the signal strength available at each output.


• Combined VHF/UHF inputs
• Gain: 30 dB, 54 to 1002 MHz
• Includes a switchable FM trap
• Outdoor rated housing
• Mast mounted amplification unit with indoor power supply which connects via coaxial cable
• Preamplifier and its power supply can withstand up to 140° F temperatures



CM-7778 TITAN 2 Antenna Preamplifier - Medium GainOUT OF STOCK  USE AP8700
The Channel Master television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This antenna amplifier is a high gain, low noise preamplifier used for medium to weak signal areas to allow a weak signal that is present at the antenna to be amplified to a viewable strength. The CM-7778 preamp offers less gain than the CM-7777 but still has plenty of gain to get the signal from the antenna to the TV set. This preamp is a perfect choice if you are in a medium strength signal area but are still having trouble receiving good signals. Preamplifiers are also used if you anticipate distributing your signal with a digital splitter to multiple outlets throughout your house as splitters reduce the signal strength available at each output.

• Combined VHF/UHF inputs
• Gain: 16 dB, 54 to 860 MHz
• Includes a switchable FM trap
• Outdoor rated housing
• Mast mounted amplification unit with indoor power supply which connect via coaxial cable
• Preamplifier and its power supply can withstand up to 140° F temperatures

* Surface-mounted components for automated production and consistent high performance.

* Rugged die-cast aluminum housing - fully shielded.

* Simple installation - hardware included.

* High gain and ultra low noise figure from latest generation transistors give optimum sensitivity.

* Ultra linear transistors provide high output capability for optimum signal handling.

* Optimum filtering for rejection of out-of-band signals.

* Uninterrupted operation even under the harshest environmental conditions.

* Full lightning and surge protection.

* Cool running, redesigned 117VAC power supply, Model 0747 is included with each model. UL and cUL listed. (Model 0747 power supply also available as a separate model.)
