The Mighty Rhombic is the "KING of Wire Antennas".

This is Scientific Technical Engineering, & Mathematics (STEM), Blog Site for the K0UO Antenna University, The Lost Art of the Nostalgic Classic Rhombics Arrays

The blog site has design, modeling, and construction information for building large HF Rhombic arrays, V-Beams wire arrays, HRS Curtain arrays, Long wire, baluns, LPDA Log yagi, Feed-lines, Beverage receive antennas, BOG, Traveling Wave antennas, Delta loop multi element beams, Diversity transmit HF radio, lightning protection, & antenna vibration dampening. Info on Icom Diversity receive for the IC7610, IC7760, & FlexRadio along with overviews on VOA, W6AM, and W7YRV Rhombic sites. Blog topics about the K0UO Rhombic farm and antenna test range, 4KS Walz Airport near Kiowa, KS.

Steven Walz, known as K0UO which is his amateur ham radio station call, has an antenna testing range site known as "Antenna University". The Primary Rhombic Antenna Farm, Site # 2, & RSI Test Range, which has the use the 4KS airport, for far field measurements, using portable towers and large drones, loaded with calibrated RF survey instruments for Commercial, Amateur Radio, STEM, DOD, school or University Research. Decades of building huge arrays, teaching, and performing RF surveys.

The ARRL, RSGB, Switzerland, and so many other amateur radio organizations use the Diamond Logo, which looks like a Rhombic antenna. "K0UO has, Miles of WIRE, in the AIR, and ON the AIR daily"

Steve Walz known as K0UO (his FCC Amateur radio call), is working on the "Lost Art of Rhombics" with four of these large wire antennas, at 100 to 160 foot high, X-Rhombic, and three 1200 foot V-Beams (VEE) antennas at the Kiowa, Kansas QTH. Which are beaming to fourteen DX areas, with phasing for more steering. There is also information on large distributed fed curtains arrays, LPDA, and beverage receive antennas. K0UO is home of the Re-entrant Rhombic, which is 90% efficient by re-phasing the power instead of heating up termination resistors. The Rohn R20, 25, 35, 45, 55, 65G, Rigid Tube Tower Series 26KD Tower, the J Tower, and the C Tower are reviewed.

I have contacted 200 countries on 160 meters, and it wouldn't have been possible without the beverage antennas.

The K0UO antenna farm is proudly using parts from many legendary stations, to continues the tradition they started with the big arrays, like the VOR (Voice of America), Armed Forces Radio, DoD, W6AM Don Wallace, BBC, Art Bell W6OBB Big Loop, W7YRV Roy Callison, and others. So symbolically those large Nostalgic historic stations are still, "On the Air Daily" by K0UO using an extensive array of towers and antennas. Also read about the K0UO Remote ham station.

See my call on QRZ, https://www.qrz.com/db/K0UO, or type in my call K0UO for more information and photos. Each Rhombic antenna uses 1000s of feet of 3/8" cable for the array wire, covering many acres each. They are erected on numerous towers and 100 foot wooden utility poles, also the site has three large V-Beam antennas which are over 1200 foot long each. Miles of wire in the air and on the air, spread out over many acres. "Build Them and the DX will Come"!

The K0UO Rhombic Farm is the largest & highest gain HF ham wire antennas array farm, currently still in use anywhere in the world.

The KØUO Rhombic Antenna Farm in Kansas, consist of many acres, with "Miles of Wire in the Air & On the Air".

A HF Rhombic antenna is an excellent choice for commercial, maritime shore stations, military, broadcasting, frequency agile, requirements, high speed traders, diplomatic, EME, and big gun contest ham amateur radio stations.

The K0UO and RSI Corp. - Radiofrequency Safety International antenna test range site makes use of the 4KS Walz airport near Kiowa, KS and its surrounding area as a practical learning environment for STEM (Scientific, Technical, Engineering, & Mathematics) antenna projects in a real-world outdoor setting. If your group has a School or University aerospace or antenna research STEM program, please let me know. We are using AI, which is now becoming an advanced tool in analyzing, developing, and expanding research in Environmental, RF, and antennas. Efficiency, Flexibility, Reliability at K0UO "Antenna University". Note, this K0UO blog uses dB gain, not dBi when providing antenna gain data, don't be fooled by dBi

You have to check it out Roy W7YRV, blog that he created back in 2013. Roy is in a his nineties now and I had a visit with him in January 2019 at his QTH.

Roy entrusted me with his drawings and other information that I will be posting on this website in the future. Roy is SK Sept 2020
