A rhombic antenna is a broadband directional antenna co-invented by Edmond Bruce and Harald Friis, mostly commonly used in HF (high frequency, also called shortwave) ranges. It is named after its "r...

Welcome to Joby's Rhombic Ranch! ... As I studied the ARRL Antenna Handbook I learned about the various types of antennas. I couldn't get excited by dipoles, loops, yagies, or quads because I wanted one antenna that would cover many bands and produce a strong signal.

T2FD The Forgotten Antenna - "Some have called the T2FD a ""squashed rhombic"" antenna. It does bear some design similarities to the non resonant rhombic, but theoretically it is admittedly inferior. However, the T2FD performs well in a modest amount of space."

Rhombics are high gain directive wire antennas. A rhombic is shaped like a diamond, if you're looking down on it. I.e., there are 4 'legs', 2 end 'points', and 2 side 'corners'. ... With this setup, I've finally achieved a good SWR over the entire bandwidth of the antenna; less than 1.3:1 from 10-60 Mc. At the important...

Why rhombic antenna array fell out of popular use gain of rhombic antennas ... Model of a Rhombic Antenna ... After all, the gain is a whopping 14.42 dBi for this 414 foot long 290 foot wide rhombic antenna. But to get a good idea of the real gain, we should compare it to a dipole or some other standard antenna at the same height.

Rhombic antenna experiment ... Some years ago I became interested in a special type of antenna: the Rhombic antenna. I wanted to know if it really was as good as you hear in all the stories about them, and, if we could use them in our contest applications.

The rhombic antenna is a diamond-shaped antenna, suspended between 4 masts. The 3 parameters of a rhombic antenna are: - l : antenna leg length; - g : one half of the large interior angle; - h : antenna height; All legs of the antenna are the same length, and opposite angles of the diamond are equal.

Rhombic Antenna is a topic in the Elmers forum at eHam.net. - eHam.net is a Web site dedicated to ham radio (amateur radio). ... I am wanting to build a 80 meter rhombic antenna. My property is at 1400 ft. above sea level. Completely clear of trees and about 150 ft. higher than my neighbors. The property is about 330 ft.
