The Mighty Rhombic is the "KING of Wire Antennas".
Please stroll down below this header to see all the blog topics, (ranging from antennas, baluns, VOA sites, to feed-lines)
The ARRL, RSGB, Switzerland, and so many other amateur radio organizations use the Diamond Logo, which is in fact a Rhombic antenna.
K0UO is working on the "Lost Art of Rhombics" with four of these large wire antennas, and two 1200 foot V-Beams (VEE) at the Kansas QTH. These are beaming to the eight main DX areas, with phasing for more steering. There is also information on large distributed feed curtain and beverage antennas.
See my call onhttps://www.qrz.com/db/K0UO, then type in the call K0UO for more information and photos. Each Rhombic antenna uses over 1/2 Mile of 3/8" cable. They are erected on 100 foot wooden utility poles, also the site has two large V Beam antennas which are over 1200 foot long each. Miles of wire in the air and on the Air. Build Them and the DX will Come!
