Another build of the 5/8ths vertical 10m antenna. This is a simple step-by-step instructional video that will have you building your own cheap, but effective DX 10m antenna in about 2 hours. I needed a portable 10m DX antenna in a hurry for the 10 on 10m FM UK YouTubers event which was taking place the following day.
The original build video with design explanation can be found here: youtu.be/eboJV6rY4a4
Part two of the original build & test series can be seen at: youtu.be/5n16SfU5kco
and part three at: youtu.be/RTjd4x_NzIg
The parts for this simple DIY build probably already exist in your shack? If not, they come to about £5 for the air-wound choke model, or about £10 if you go for the ferrite choke model. A list of parts:
Main Antenna = 3.5m RG58 coax + 3.25m of insulated wire
Air-Wound Choke = 3.6m RG58 coax (or) 9 Turn Ferrite Choke = 73cm RG58 coax (+ the ferrite) - a 12 Turn on a 52 or 61 core will use a little more coax, say 1m in total.
Matching Stub = 71cm Westflex 103 coax
G3TXQ chokes: karinya.net/g3txq/chokes (follow the links mid-page for detailed and updated analysis for specific ferrite types)
Here's a link to the Westflex-103 specs if you have trouble sourcing some: whwestlake.co.uk/westlake-pdf/WF103.pdf
