5/8th wave 10 meter vertical antenna build

 

If you need a bit of gain (approximately 3dBi) for your next 10 meter band antenna, please consider this vertical antenna project from Ian (G0CNN).

In this video, Ian converts an old 5/8 wave CB antenna into a 5/8 wave 10 meter band antenna. The "reengineered" vertical is easy-to-make and performs very well with its new identity.

Ian takes us step-by-step through the entire process, which uses locally available materials and some simple tools found in your ham shack.

Here are some comments from Ian (G0CNN):

Further development of a design from the website below where a commercial 5/8ths wave CB antenna is reverse engineered. This enhanced model is tuned specifically for the 10m amateur band and also adopts a ferrite choke, which is an improved option over the air-wound choke which is also shown in the build. 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 Original CB antenna article: https://radioaficion.com/cms/sirio-ga...
