Digital Cameras Photo Reviews of Channel Master CM-7778 Titan Medium-Gain Mast Mounted PreamplifierCustomer Review: Great amp Summary: 5 Stars
Initially I bought the db8 antenna which did great on UHF and the upper VHF. I was able to get channel 2 with some drop-outs but once I used an amplifier (7778) and a splitter, I completely lost the channel. That channel had about a <50% signal strength before the amp or the splitter. I decided I wanted to go with a better VHF antenna since the cm-7778 amp will allow me to combine inputs form two antennas. Once I connected it, it worked flawlessly. The strength after the amp and the splitter jumped from 23% to 79%. The only drawback is that channel 7 which used to be 85% with the DB8, dropped to about 75% which is fine with me since with a digital signal you either receive a channel or you don't! I believe that is due to the fact that the 3018 is directional and it wasn't exactly facing the channel 7 towers.
I am assuming a lot of folks are trying to do the same thing that I did which is get a good VHF/UHF reception to 4 different TV outlets so I am going to list what I used.
First problem would be which amp and how would I power the amp. I went with the channel master 7778. The great thing about it is that you can put the power supply inside the house and it will send the power through the cable line to the amp outdoors. The trick is you have to use a "power pass through splitter". The one that I used is sold by amazon. Do a search for "4-Way Digital Cable and Satellite Splitters". If you live very far from the tower, you can try the CM 7777 which has a slightly better gain but could result in an overload if you live close.
For the antenna choices, it depends on your location. In my case I am about 40 miles away from the towers. I went with the DB8 for the UHF channels and the Channel Master 3018 for the VHF. I recommend going with two antennas because the DB8 is not directional and it does not have to face the towers and the 3018 is. The DB8 has about 75 miles range for UHF. The 3018 has 35(as per the box). For VHF, the DB8 is unclear on the range, and the 3018 has about 60miles. If you only care about UHF (channels 14 and up), the DB8 would be just fine. If you live far from the towers, you can go with one of the higher end deep fringe antennas from channel master. It doesn't do any good to spend more money on a bigger bulkier antenna if you really don't need it.
Using the cm7778, i was able to split the signal first using the 4-way splitter above then i split two of the outputs further using 2-way splitters and the signal was still good for all channels! On top of that, I have the dish signal multiplexed with one of the outputs through the same line and I still get both excellent antenna and dish signals. This amp/antenna combination was definately worth the money!
Description of Channel Master CM-7778 Titan Medium-Gain Mast Mounted PreamplifierThe 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 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 enough gain to get the signal from the antenna to the tv set. this preamp is a perfect choice if you are in a strong to medium strength signal area but are still having troubles receive the strongest signals. preamplifier are also used if you anticipate distributing your signal with a digital splitter to multiple locations throughout your location as splitters reduce the signal strength per output.
