Optimum filtering for rejection of out-of-band signals.
Power supply goes in the building and sends voltage up the antenna cable (see diagram in Specifications tab)
Surface-mounted components for automated production and consistent high performance.
Cool running, redesigned 117 VAC power supply, Model 0747 is included with each model. Output voltage is +15VDC. UL and cUL listed, Power supply also available as a separate model.
Power supply and pre-amp are connected to the antenna using RG6 coax cable. An RG6 cable is run from antenna to pre-amp, from pre-amp to power supply, then from power supply to television. Power supply does not have to be outdoors.

Includes a switchable FM trap
A Pre-Amplifier (pre-amp) is a mast
or antenna mounted amplifier used primarily to eliminate "snow" on
the TV screen. Snow is actually electrical noise that is generated by the TV
receiver and other electrical devices. The objective of any antenna
installation is to deliver enough signal to the TV set to override the noise
(snow). A "weak" signal is one that is not strong enough to override
the level of the noise in the set. Another obstacle is the signal loss incurred
while traveling through the transmission line connecting the antenna to the TV
set. An antenna that has acceptable gain at the antenna tapoffs but encounters
excessive loss due to long cable runs will also deliver a "snowy"
picture to the TV set due to not enough signal makes it to the set to override
the noise level. A pre-amp would be used to compensate for the losses in the
transmission line as well as the noise level of the
Mast Mounted Preamplifiers
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.
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
• Number of
Inputs: 1 (VHF UHF
• Input and Output Impedance:
• Input and Output Connectors: F Type Connectors
The power supply that comes with this amp goes
inside the building, so you do not have to run a separate cable for
power. The unit inside the building injects voltage up the coax
cable, so there is no need to put a power supply outside. Be sure not
to place any devices in-line between the pre-amp and power supply, or the
voltage will be blocked and the unit will not function

The TV/Ant terminals are labeled on the underside of the power supply. Once mounted the label cannot be seen. It would be better to label at the terminals. I marked them myself with a Sharpie pen.
DTV without paying a cable company!
- Santa Rosa, a Rosa CA - 8/2/2011
I recofigured my outdoor antenna mast when the digital changeover took place.I installed a dedicated VHF ch 7-14 and a UHF long boom yagi. The CM-7777 VHF and UHF input pre-amp is installed at the mast very close to both antennas. My cable feed is at least 60 ft directly to the TV with an additional distributing amplifier in between. I live in central Sonoma County CA on a hill top 540 ft above se
CM7777 Works Perfectly
- Milford, CT - 10/3/2011
Our home in CT is 62 miles from the transmitter in NYC and channels 2 CBS and 4 NBC were impossible to get.The 7777 is now mounted on our antenna approx. 25 off the ground and pushes through 50 of cable to a 3-way splitter.The TVs are then approx. 15 20 and 40 away and we enjoy a full range of channels on all of them including 2 & 4. Completely worthwhile investment.
Weak cable terminals

The directions for the setting of the switches are poorly written. The coax connectors are easily twisted off the circuit board if a wrench is used for tightening.
System Overload Causes Failure to Functi
- Eastern Shore o, Eastern Shore o - 7/23/2012
The CM-7777 failed to work completely because as Channel Master technical staff indicated the antennalocation is too close to the TV stations.Most stations are in the 30-49 mile range there are otheres further away and one is at about 20 miles. These conditions caused the amplifier to completely shut down.If that is the case an appropriate warning should be posted to save some users
- Louisville, sville KY - 11/24/2012
The new version of th CM7777 is an awesome pre-amp. It is supurb for those who live near TV stations and those who are in fringe to deep fringe areas and hard core DTV DXers. It use the latest pHEMT device technology which gives abalance of low noise excellent distortion and high-gain. I further improved my pre-amp in the fringe - deep fringe perfomance by replacing the SMD ICs with ones that
HDTV reception excellent

The product results was better than expected (for my area).I live 45 miles from Gainsvile Fla.130 from Tallahassee90 from Jaxsonville140 from Tampa and 60 from Ocalla. I have a very used antenna on a 40 ft tilt tower.I used as few couplings as possible on a 110 ft cable.Antenna rotor lets me swing to any of the locations and receive a very good HDTV signal
Enables UHF antenna for VHF-hi
- Chicago suburbs, Chicago suburbs - 3/28/2013
My VHF locals are 29-miles away so it does not overload for me (as some say theyve experienced with a nearby VHF local or FM tower).Use it with a UHF bowtie (Antennas Direct DB4) antenna and it pulls in the VHF-hi stations reliably as well as the primary UHF stations.Without this preamp the VHF stations were dicey at best for me and pixilated during tree movement during storms.I prefe
I would buy CM7777 Titan2 again.

Help me get Tv station that we needed
- Topsham, ME - 3/28/2013
I live in a marginal receiving area and the mast should be higher. I credit the preamp and good antenna for good reception. Everything seems sturdy and the outdoor unit appears durable and weatherproof.
get it done

Very Good Pre-Amp
- White Plains, ite Plains N - 3/28/2013
I am all DTV off air. Very good antenna preamp. Works exactly as described the picture does come in clearer as well as more channels are now viewable. With Digital TV some stations I now get video only since sound is broadcast separately I know the amp provides gain for the audio too but my tuner does not pick up all the new stations I now get with the amp installed with sound. So total I get

[...] the product works great
Better performance than older tech.
- Port Charlotte, FL - 7/5/2013
My CM0747 gave up the ghost after 7 1/2 years. The replacement, CM7777 is better performing, bringing in twice the number of distant programming.
One small detail, the signal does *not* come from the power supply; there is a signal/power splitter installed between the amp and PS. This is elegant since the AC outlet may be distant from the signal run.
made a noticeable difference
- Marysville, CA - 12/30/2013
had a cheap RCA preamp on our antennas but when I had to relocate the antennas to the other side of the house to avoid a neighbors tree the signal got weak enough that it was borderline quite often. There is a good 75 feet of cable now between the antenna and the TV. Swapped out the amps and on the HD Homerun signal strength went from low 50s to solid 70.
Before when the antenna would move at all the signal would fail. Now turning it a bit from side to side doesn't affect the signal at the TV.
11 Channels perfectly clear. BYE BYE satellite !! Dish Network !!!
