The iC-AG1 ICOM Noise 430 MHz Preamp Box is a high-performance, standalone preamplifier designed for use with ICOM's IC-705 and IC-706 series of transceivers. This preamplifier is specifically engineered to reduce background noise and improve the overall signal-to-noise ratio, resulting in crisper, clearer audio quality.
The iC-AG1 is housed in a compact, durable aluminum enclosure that measures just 1.5 x 3.1 x 3.1 inches (38 x 79 x 79 mm) and weighs less than 10 ounces (280 grams). Despite its small size, the preamplifier packs a powerful punch with a maximum gain of 27 dB and an input impedance of 50 ohms. The preamplifier's low-noise design ensures that even the faintest signals can be heard and deciphered, making it ideal for use in challenging environments such as crowded RF bands or weak signal conditions.
The iC-AG1 features a built-in automatic gain control (AGC) circuit to automatically adjust the preamplifier's gain based on the strength of the incoming signal. This ensures that the preamplifier always delivers the optimal gain for the current signal level, preventing distortion and ensuring that every detail of the audio is preserved.
The preamplifier also features a high-pass filter to remove any low-frequency noise that may be present in the signal, further improving audio quality. The filter can be adjusted between 50 Hz and 200 Hz to suit the specific requirements of the user.
The iC-AG1 is easy to use, with a single input and output connector that can be connected directly to the transceiver without the need for additional cables or adapters. The preamplifier is powered by the transceiver itself, eliminating the need for an external power supply.
In summary, the iC-AG1 ICOM Noise 430 MHz Preamp Box is a powerful and compact preamplifier that delivers crystal-clear audio quality by reducing background noise and improving the signal-to-noise ratio. Its automatic gain control and high-pass filter ensure that the preamplifier always delivers the optimal gain and frequency response for the current signal, while its easy-to-use design makes it a great choice for amateur and professional radio operators alike.
