K0UO ロンビックアンテナファーム
The Mighty Rhombic is the "KING of Wire Antennas".
This is Scientific Technical Engineering, & Mathematics (STEM), Blog Site
If you have an big wire antenna project, let me know if I can help in anyway
The blog site has design, modeling, and construction information for building big HF Rhombic arrays, V-Beams wire arrays, Curtain antennas, baluns, VOA sites, LPDA Logs, W6AM, W7YRV, Ham Radio, Feed-lines, Beverage receive antennas, BOG, Traveling Wave antennas, Delta loop wire beams, antenna vibration dampening, Icom Diversity receive for the IC7610 and IC7760. Also blog topics about the K0UO antenna test range, and 4KS Walz Airport at Kiowa, KS.
The K0UO amateur ham radio station, antenna testing range site, and Rhombic farm has the use of over a thousand acres around the main antennas for far field measurements, using a portable tower and drones loaded with calibrated RF EME survey instruments (used for Amateur Radio, STEM, DOD, school or University Research, and Commercial).

The ARRL, RSGB, Switzerland, and so many other amateur radio organizations use the Diamond Logo, which looks like a Rhombic antenna.
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, and three 1200 foot V-Beams (VEE) antennas at the Kansas QTH. Which are beaming to the fourteen main DX areas, and with phasing adding 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.
Also see the page on Beverage RX antennas.
I 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, W6AM Don Wallace, BBC, Art Bell W6OBB, W7YRV Roy Callison, and others. So symbolically those large historic stations are still, "On the Air Daily" by K0UO using an extensive array of towers and antennas.
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 site is the largest and highest gain 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 antenna test range site makes use of the 4KS Walz airport 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.
