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.

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 ...

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 ...

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 ...

Build as described above but omit the reflector. I use such an antenna for UHF (675MHz centre) DVB-T transmissions. It compares very favourably to commercial Yagis. Gain is about 6 dBi and it has two ...

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, ...

Much of the work of Spectrum Planning Group is based on well-established principles of 'antennas and propagation'. Propagation matters have received a lot of attention over the years and much has been ...
