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 ...

DIY FM dipole antenna or half wave antenna are the most used because is easy to build and cost a few bucks but has some drawbacks like little directionality, small gain. The rf dipole antenna is build ...

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 ...

After moving and installing an anechoic chamber, we needed to test the shielding effectiveness. We decided to build a matched set of 900 MHz Dipole antennas. We started by designing a half wave dipole ...

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 ...

Meaning "two poles," a dipole antenna is the simplest type of antenna, consisting of an electrically conducting wire or rod one half the length of the maximum desired wavelength. The wire or rod is ...
