Extraordinary Terrestrial HDTV reception requires extraordinary technology, and as there was previously no high performance amplifier commercially available, DataWave RF has developed the ULNA/INT Ultra Low-Noise Amplifier which is installed internally to DataWave RF MaxChannel Series Antennas and also can be added to Fracarro Yagi antenna models.

The key feature of the DataWave RF ULNA/INT is its extraordinarily low average device Noise Figure of 0.45 dB, but also important is its immunity to signal overload due to its very high third-order intercept point of 36~38 dBm.

The professionally engineered "ULNA/INT" also features superlative input impedance matching of less than 1.8:1 VSWR. Low VSWR is essential to preserving the benefits of this ultra low Noise Figure. High input VSWR defeats any low noise benefit, since much (50-90% with many other LNAs) of the antenna signal will be lost.

Internal to the antenna, the "ULNA/INT" -provides- the antenna-element terminals, eliminating any possible losses from connectors, coax jumpers, impedance mismatches, etc. This design feature alone can provide improvement of 0.5~3 dB and more over amplifiers that attach to the antenna via coaxial cable.

Amplifier noise directly subtracts from the available signal strength, which becomes critical for weak signal reception. Typical television mast amplifiers have a Noise Figure specification in the range of 2.0 - 3.5 dB, with some brands/models as high as 4 dB and more. When attempting to receive a weak station, this noise power is imposed onto the signal, which is equivalent to cutting the useful gain of the antenna, sometimes by half or more ! The result is signal drop-out (video freezing, audio stuttering), or failure to receive the signal altogether.

Even if all of your stations are usually strong, there can be vehicular interference, that is, reflections from planes, buses, vans, etc, that temporarily but significantly reduce signal strength, and these signal interruptions will also be minimized by the DataWave RF "ULNA/INT".
