![]() ![]() ![]() Televes amplifiers feature advanced auto gain control that allows weak signals to get maximum amplification while limiting strong signals to stop potential damage.įM Trap: FM Traps strongly reduce FM Signal. Most amplifiers will pass all frequencies, but read carefully.Īuto Gain Control: This feature allows an amplifier to automatically reduce gain if a signal is so strong that it could harm your TV’s tuner. Using a VHF/UHF antenna on a VHF-only or UHF-only amp will result in one of those frequencies being blocked. If your TV Antenna receives VHF and UHF signal, you need a pre-amp that passes VHF/UHF signal. A high noise figure would be 4-6dB.įrequency VHF UHF FM: This one is pretty simple. ![]() Channel Master’s CM7777 is sought after for its low noise figure of about 2dB on UHF. ![]() The higher the noise figure, the lower the sensitivity of the tuners being used to pick up the signal. When an amp is added to a system, a small amount of signal noise is generated. Noise Figure: With digital signals, this often is more important than gain. If you only have 15dB of loss on your longest cable run and you use a 30dB amp, you can overdrive your tuner with too much signal. Warning: Higher-gain amps aren’t necessarily better. For instance, if you have 100ft of RG6 cable, which has 8dB of loss, you must make sure your amp is at least 8dB or stronger. You must make sure your gain is equal to or greater than your signal loss. Gain: This is the most important factor in choosing a preamplifier. To help you better understand and choose the right TV antenna preamplifier, here are some terms used to describe certain qualities of these devices: Call us at 877.312.4547 so our product experts can match you with the best preamplifier for your TV antenna installation. We also carry three Televes TV antennas that have built-in Televes preamplifiers, as well as a Televes 2-input and 3-input mast-mounted preamplifiers. This preamp has a 1dB noise figure, 18dB gain, and offers twin amps for separate VHF/UHF amplification. This device reduces signal drop out and pixelation for your HDTV antenna. If you need a preamplifier for your TV antenna installation, try the Winegard Boost XT ultra low-noise antenna preamplifier. When using an RG59 Coax, you’re losing 10dB of signal per hundred feet of cable.If you’re using an RG6 Coax Cable, you lose approximately 6dB of signal for every hundred feet of cable used.Here are two rough estimates of TV signal loss from long cable runs: If you’re not sure whether or not you truly need an amplifier, give us a call at 877.312.4547. Not only that, over-amplifying a signal can damage your TV’s tuner. If you have good signal in general, but it’s occasionally interrupted by trees or weather, an amplifier might not help. If the signal is so weak that a long cable run will make it impossible for your TV’s tuner to detect, then you need a preamplifier. With digital signals, the only thing you need to worry about is whether the signal is stronger than the noise around it. How do you know you’re getting the right one? The key to choosing a preamplifier is to get one with enough gain to make up for the signal you lose from the cable run.Īn amplifier isn’t always the answer. When it comes to TV antenna preamplifiers, there are many makes and models, all with their own unique features and benefits. These devices usually are placed outdoors near the TV antenna. Depending upon your TV antenna installation, you might need a preamplifier, distribution amplifier, or both of these devices.Īs previously stated, a TV antenna preamplifier is used to compensate for signal loss commonly experienced in installations with long cable runs. A distribution amplifier is designed to amplify a signal for the purpose of overcoming losses due to splitters. A preamplifier is used to compensate for signal loss from a long cable run. An amplifier is a general purpose term for any circuit or device that keeps the characteristics of a signal the same while increasing the amount of current. Solid Signal shows you whether you need a preamplifier or a distribution amplifier.Ĭhoosing the right TV antenna amplifier is about finding the right preamplifier or distribution amplifier. A TV antenna amplifier corrects weak signal in your TV antenna installation. ![]()
