My Certificate
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.
Approximate radiation pattern on a Great Circle Map from my home QTH:
The great circle maps were generated here: https://ns6t.net/azimuth/azimuth.html
I know the radiation patterns are not totally accurate, but they’re good enough!
Update 14 April 2022, also worked on 30m.
This makes my Galapogos Island confirmed on LOTW 5 bands:
Two in a row!!
I need to make one of these!
A look around the antenna field …

I didn’t have as much time as I would have liked with this contest with almost all my operation focused on the Sunday. A total of just 260 QSO of which exactly half were on 15m (the band I had decided to focus on) with rest split: 80m (7), 40m (35), 20m (88). 36 US States/Canadian Provinces worked on 15m.

Can’t decide whether to go for original (tr)USDX orange or green. For scale here is an image next to one of my QCX Minis:
