A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Dipoles are a classic builder’s antenna, after all they are usually little more than two pieces of wire and a feedline. But as [Rob] shows us in the video below, there are a few things to consider.

I've constructed hundreds of antennae in the past. Bowtie dipole arrays, biquads, parabolic reflector dipoles, straight up yagi, logarithmic yagi, log periodic, heliacal and simple 1/4 whips. So when ...

Antennas are an essential part of radio telecommunications equipment, bridging the gap between electronic and electromagnetic signals. The shape and size of an antenna is a strong clue as to its type, ...

Lo and behold, the humble yet mighty biquad. The gain figure on one of these things is pretty impressive, you're looking at 8-10 dBi. The double biquad detailed a bit lower is about 2-3 dBi higher. A ...

ANGOLA, N.Y., Nov. 19, 2025 (GLOBE NEWSWIRE) -- TX RX Systems is introducing a refreshed line of dipole and stacked dipole array antennas designed for customers who depend on reliable communication in ...

Written by Joseph Darlington, P.E. When building any radio system, the scarcest and most precious system component is not the radios, the antennas nor the towers, but available “clean” radio channels ...
