![]() If the signal levels are already bad at the input to the amplifier, they will not be improved by amplifying them. The reason for this is to ensure the amplifier is receiving sufficient signal levels. For Blue and especially Purple zone channels, or installations with very long cable runs and a high number of TV outlets, the Amplify Adjustable Gain Preamplifier (CM-7777HD) on the high gain setting may be the better choice.įor Red, Blue and Purple zone channels it is preferred to use a preamplifier at the antenna instead of a distribution/drop amplifier in the home. In most cases when the channels you are trying to view are in the Red zone, the Amplify Adjustable Gain Preamplifier (CM-7777HD) on the low gain setting should have sufficient gain, even when feeding up to four TV outlets, as long as the coaxial cable lengths are not excessively long. The Amplify Adjustable Gain Preamplifier (CM-7777HD) has a switchable 17-30dB adjustable gain setting. The Titan 2 High Gain Preamplifier (CM-7777v3) has 30dB of gain. The Titan 2 Medium Gain Preamplifier (CM-7778v3) has 16dB of gain. Preamp's Cannot be used with Amplified Antennas.Ĭhannel Master provides three preamp's with different amounts of gain. Since the splitter used to connect multiple TV outlets in the home causes signal loss, a preamplifier at the antenna can help overcome these losses by increasing the signal levels coming from your antenna. One more situation that may benefit from use of a preamplifier is when multiple TV outlets are being fed from the same antenna. ![]() If there is 50 feet or more of cable between the antenna and TV set, a preamplifier may provide an improvement. If the station/s you want to receive are in the Red or Grey you most likely will see an improvement in signal strength by installing a preamplifier.Īnother possible need for a preamplifier will be on installations with long coaxial cable runs from the antenna to the TV. One good way to determine if a preamplifier is needed it to enter your address into the Antenna Selection tool and review the listing of available channels at your location. Since this is not usually available for most home installations, determining the correct preamplifier can be challenging. The only sure way to determine if a preamplifier is needed is to measure the received signal levels with a field strength meter. In areas close to TV transmitters, a preamplifier is usually not needed and can actually cause problems as it may cause the signal levels to be too high. In areas distant from TV transmitters, overcoming this loss is necessary since the signals can be weak. Over amplification can cause issues with the television tuner’s ability to receive and display some or all channels.A mast or antenna-mounted preamplifier is used primarily to overcome the loss in the coaxial cable between the antenna and the TV. Due to the high gain output of this product, it can result in over amplification if not used in the appropriate scenario. The Titan 2 High Gain Preamplifier is recommended for professional installers only. The indoor unit is stationed indoors and connects to the outdoor unit via coaxial cable. The Titan 2 High Gain Preamplifier is a two part unit, an outdoor amplification unit which is mounted on the mast of your antenna system and an indoor unit which powers the outdoor amplification unit. This antenna amplifier is a high gain, low noise preamplifier used to allow weaker signals at the antenna to be amplified to a viewable strength, and is ideal for installations in which all broadcast towers are located at a distance of more than 80 miles. ![]() ![]() ![]() The Titan 2 High Gain Preamplifier will amplify signals received by your antenna. ![]()
