Brand new. Uptronics preamp and filter for aircraft ADS-B reception. Used with SDR aircraft receivers for flight tracking. These units are very high quality and very effective. Was going to set up a complete second receiving station but never got around to it. So, this has been sitting in the drawer brand new. Simple installation. Connected antenna to the antenna input side and your receiver to the output side. Power up with a USB-C power supply and cable (not included typical 5V charger PS works). I have one installed on my regular flight tracker setup and in dramatically increased the number of hits and planes I could receive. You will need a suitable cable to go from the preamp to the antenna input on your receiver, usually SMA to SMA. Heres the data from Uptronics: This is a SAW based unit which is cost effective and gives excellent performance gains. All our preamps are compatible with most USB SDR Dongles such as the RTL USB, Airspy, Fun Cube. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB-C cable (Not Supplied - See related items for a suitable USB Type A to C Cable). Bias-tee voltage input is 5V. Note: Unlike previous models, component supply issues mean bias-tee input voltage is 5V max. This unit is a small filter and preamp designed to go between a software defined radio receiver and an antenna. Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter in this design to reduce the noise factor of the unit. This particular model is tuned for use with ADS-B frequencies (1090MHz). The LNA used is a MiniCircuits PSA4-5043+ which provides about 16dB of gain @ 1090MHz. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB. High quality SMA female connectors are fitted for antenna input and radio output . No warranty, no returns. Im not the manufacturer or a store, just a guy with a spare unit. Its brand new. FREE priority mail shipping in the USA. Overseas bids welcome but you have to pay shipping via ebay global international.

Founded in the early 90s Critical MASS Audio has established itself over the 30 plus years as one of the finest audio manufacturers in the world. Many even claim Critical MASS Audio is in a league of its own due its unparalleled combination of the highest possible level in sound, design and finish. What is for certain is the proven consistency in delivering excellence for ears, eyes and hands without any kind of compromise - materialized in unique masterpieces. Words alone cannot effectively describe the CRITICAL MASS AUDIO sound. Objective descriptions such as ruler-smooth frequency response, ultra fast step response and excessive adjectives like neutrality and amazing soundstage could be used however these qualities are a successful by-product of accurate engineering stemming from Critical Mass Audios goal of reaching for perfection. Sonically, the sheer scale and dynamics of the music in this Car Audio system was bloody extraordinary. The effect was Audio Oasis! Award material all the way. The sound was effortless, fluid, natural, organic, and had the sort of transparency that I associate with only the finest sort of designs that Ive encountered on this planet.

Rated #1 by the Pros in Car & Audio Magazine. Founded in the early 90s Critical MASS Audio has established itself over the 30 plus years as one of the finest audio manufacturers in the world.

Critical MASS amplifiers are manufactured and tested to meet the highest component quality and control standards. Engineered to provide decades of musical enjoyment. Critical MASS is a Car Audio company whose Super-Fi electronics have made innovation history in the world of high-end mobile sound CA&E. Critical Mass was formed from the World’s First Car Audio and Enhancement school by one of Car Audios first innovators and most influential people in our industry who started the worlds first Car Audio and enhancement school back in the late 1980s “CMA”, from this school Critical MASS was started in Orlando, FL, in 1990. Till this day parts of the technical principles and teachings of CMA are used industry wide in Mobile Electronics teachings and books by associations such as MERA and CEA. Over the past decades Critical MASS has continued to innovate and now leading the way with the Critical MASS $259,000 CES-5.1 one of a kind Esoteric ESL sound system. Not only does Critical MASS make the Best and most expensive car audio system in the world, but this system is so good, that when Car Audio Magazine tested the least expensive part of our $259,000 ESL system “the UL12” called it Perfect , and the BEST and added that it was so good that he would sell a few things, to own one because its worth every dollar! In addition the Critical MASS UL12 was rated #1 over all others by Car Audio Magazine, including companies such as JL Audio, Image Dynamics, Alpine, Xtant, Kicker, Arc Audio, MB Quart, Digital Designs, Cerwin-Vega, Orion, Phoenix Gold Earthquake etc… In other words Imagine how good the rest of the system must sound if the least expensive part of it is the worlds BEST?
