Welcome to K0UO's premier ham radio antenna site farm, spanning hundreds of acres dedicated to innovative design and rigorous testing of antennas. The largest in the world, so join me in advancing the field of ham antennas radio with cutting-edge technology and expert guidance. This station has been very competitive, and has won many major worldwide amateur radio contest. 
High-Frequency Stock Trading groups should use the rhombic antenna.

The Defense Technical Information Center is RSI's central facility for the collection and dissemination of scientific and technical training information. RSI supplies training and assessment services to the United States and other governments.Welcome to the K0UO Ham Radio Station, home the world's largest antenna site and test range, spanning impressive 1,200 acres. Featuring miles of antennas and towering structures—including FCC-registered reaching up to 195 feet—our facility is a dream destination for serious contester and big gun operators. With numerous -foot wooden powerline poles, concrete silos, and portable mobile towers, the K0UO Rhombic Farm stands out for its significant height and capabilities. Registered under Antenna Structure Registration number 1216715, our station is recognized in the FCC public file, credibility and verification that sets us apart from other so-called big gun ham stations. The station and antenna farm uses very complex highly engineered arrays.

k0uo uses Re-entrant Rhombic array is one of the highest forward gain HF antennas with its 90% efficiency, the highest forward gain of any HF ham antenna. Also a  world-class multiple stations, with   many large LPDA yagi type beam antennas, 195 to 300 foot towers, and multiple very large wood power-poles. Antennas from 160 meters up to 2 meters. Using the new Icom IC7760 as the main transceivers.

K0UO has years of expertise in contesting, DXing, using cutting-edge engineering and technology.

K0OU uses many very high-gain directional LPDA-Yagis beamed at all continents, large 160 -40 meters four square verticals, stacked systems of rhombics, V-beams, and curtain arrays, The achieved goal has been met to have a world class station with multiple antennas combined (stacked) for increased gain and better performance on all the amateur bands, that are optimized for maximum gain. All utilizing optimum take off angles.

With 1200 acres near by to test and build all types of antennas and tower pole supports, also the largest ham radio station in the world with milrd of wire arrays and many towers, Antenna Test Facility ATF, electromagnetically-quiet area.(since OH8X in Finland, tall tower and 160 meters beam  in Finland. was destroyed by a storm in 2013).
Miles of antennas for ham radio 
dozens of tall antenna support structures, like FCC registered towers up to 195, to 300 foot on a near by Gypsum hills site, numerous 100 foot wood power-line poles, concrete silos, and portable mobile towers. K0UO near Kiowa, KS has High-Performance Antennas: Using large stacked LPDA-Yagi beams, Rhombics, Curtain arrays, Four-square phased verticals on specific bands, optimized for low noise and very efficient and high gain K0UO Rhombic antenna farm which is the highest forward gain array and largest area on 1200 acres in use by any amateur ham station DX, remote, or contest station in current use any where in the world
The K0UO Rhombic farm and antenna test range is one of the very few ham radio stations that has a tower which is tall enough and required by the FCC to have a registration. The Antenna Structure Registration or ASR tower number is 1216715. So the K0UO site, station, and antenna is in the FCC public file. used in conjunction with RSI Corp of Kiowa KS seehttps://www.rsicorp.com/dtic. Use for DOD and commercial wireless telecommunications groups.

RSI Corp is a Professional, Scientific, and Technical Services company that can Handle technical management, RF testing logistics, and integration of measurement instrumentation in collaboration with the facility. The K0UO antenna test range site is a

highly technical facility used to precisely measure an antenna's performance characteristics, such as its radiation pattern and gain.  The K0UO and RSI test and measurement facilities feature state-of-the-art equipment/software in RF performance, supported by continuous in-house calibrations. Mechanical positioners are designed to precisely orient antennas.

The K0UO antenna test range site  has significant outdoor real estate, and over 2500 feet by the 4KS Walz airport, so anechoic test chambers are not needed. and testing site has the use of over a thousand acres around the main antennas for far field measurements. the K0UO Electromagnetic Test and Evaluation Facility is a multi-purpose, wideband, antenna test facility.
