VHF Long-Wires, V-Beams and Rhombics

October 13th Fact-of-the-Day

Long-wires, v-beams and rhombics are rarely used in VHF and UHF applications, mostly because they tend to be difficult to rotate and because long-wires, v-beams and unterminated rhombics beam energy in two directions. However, they are very simple and inexpensive to construct. They have exceptionally broad frequency characteristics compared to Yagi's. Their dimensions are much less critical than are the dimensions most types of antennas normally used at those frequencies. They are reasonable alternatives in applications where pattern rotation is not needed and their directional patterns are suitable. ©2004 Martek International All rights reserved.
