Couldn’t sleep so thought I’d have a tune around the 20m band. Delighted to see VK0 popped up in FT8, my first VK0 QSO on any band 🙂 From DX news: “Matt, VK5HZ will be active as VK0MQ from Macquarie Island, IOTA AN – 005, starting Mid June 2022. He will operate on HF Bands, SSB, FT8, using ICOM IC-7100 transceiver and tuned whip antenna.”
Very pleased to see my BARTG RTTY score, operating with my contest callsign G2K. RX/TX: Icom 7600 / Amplifier: Acom 1010 at 300W Antennas: * 80m – Inverted L * 40m – Dipole and 1/4 wave vertical * 20m, 15m – Dipole * 10m – Dipole and 5/8 wave vertical

Spacers are 3D printed from my own design (printed in Black PETG for uV protection) Spacing between each element is 10cm (4″). The spacers (21cm long):
The mast top piece is also 3D printed in PETG:
Email me if you would like the STL files for the spreaders and mast top piece. At £20 a roll of PETG the spreaders cost 17p each, the mast head piece 29p. Less than a cup of Costa Coffee – a total of 18 spreaders. The spacers were printed on my Anycubic Vyper 3D printer.
The mast is a DX Commander Classic mast available from M0MCX at DX Commander here.
