28 MHz Antenna Project – 10m Flowerpot Antenna

Since building a 6m coaxial dipole in January 2016 and later a 2m coaxial dipole in February 2018, I have often thought how a monoband half-wave vertical coaxial dipole would perform on 28 MHz. Summer is here in the southern hemisphere, therefore now is an excellent time to construct a 10m half-wave coaxial dipole for…

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…

Construction of a 23cm 1296 MHz Bi-Quad Antenna

I’m enjoying the challenge of 23cm 1296 MHz homebrew antenna construction for SOTA purposes.  My 23cm portable antenna collection includes: 12el DL6WU Yagi 12dB gain – lightweight boom construction using a folded dipole; 6el DL6WU Yagi 9 dB gain – ruggedised all brass construction gamma matched, ideal for the Australian scrub bash; and 2el HB9CV…
