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 ...

If you’re a regular reader of Hackaday, you may have noticed a certain fondness for Meshtastic devices, and the LoRa protocol more generally. LoRa is a great, low-power radio communications standards, ...

For amateur radio operators, the quest for the perfect antenna never seems to end. Perhaps that’s because our requirements are always changing. We never quite seem to get to one design that can do ...

This article describes the phases for the construction of a Yagi antenna. The calculations of the parameters are made using 4NEC2 software. This type of antenna is used for transmissions and ...

A paper published in Nature this week details how researchers have taken a common antenna design and replicated it on the the nanoscale level. When a regular TV aerial that handles radio frequencies ...

Physicist and frequent eFlea participant Eric Einarsson built a yagi antenna to boost the reception and transmission distance for his brother’s cell phone. Eric writes: Here is some information and ...
