Antenna Project – Recycle an old aluminium VHF TV antenna and build a hand-held 2m yagi for 144.2 MHz

This 2m yagi antenna is light on the back-pocket and relatively easy to construct. This project starts with an old VHF TV antenna purchased from a local ‘Green’ recycle depot for $5.00 AUD. The repurposed TV antenna was a Phased Array comprised of two aluminium booms and four elements or eight 1/4 wave elements. Each…

RF Trap Resonant Frequency

I am constructing a lightweight 40/30/20/17/15m trap style inverted V dipole antenna for SOTA purposes. Can you use an antenna analyser to check the resonant frequency of a HF trap? Yes you can, here is a practical solution. The purpose of this post is to demonstrate how you can use a modern antenna analyser to…
