Via Southgate News and MAKE magazine news of a collapsible fabric yagi antenna developed by Diana Eng KC2UHB who has combined two craft skills in a stylish way, electronics and sewing. It’s a design for a Yagi for portable amateur radio satellite operation.
Via Julian G4ILO I came across a WSPRnet report from DM1RG on his success with a newly built KGD Antenna from the German site QRP Project. I had actually ordered their other antenna project (a Multiband Fuchs antenna that enables a single 41m wire to operate on all 8 HF bands) a few days ago and earlier tonight revisiting their site I was readng more about the KGD antenna – a very small vertical dipole – how’s 130cm for a 30m antenna that enabled a link from D to VK on 5 watts?
The Kurz Geratener Dipol antenna is no longer available as a kit but the instructions are still online – auf deutsch. I should also have a go at translating the manual. It seems to be quite an effective design. On the 40m version (pictured here from the QRP project site) – all 150cm of it – the bandwidth between SWR 2:1 points is 45kHz.
Reading about the antenna again on the same evening is clearly some kind of good omen? I can almost imagine one mounted bike mobile!
I’ve only just discovered the set of video tutorials on YouTube featuring Chris W6HFP of Buddipole. They’re clear and well shot and edited, I suspect by Steve WG0AT. And they’ve been online for over a year!
In this one Chris explains setting up a Buddipole Versatee Vertical.
