The HAB payload needs a small/suitable antenna. I decided that it would be easier and a lot more fun to make the antenna; rather than buy one. It would also reduce costs and a lot of additional knowledge and know-how would result.
Materials
Material for this are:-
| Material | Quantity | Notes |
|---|---|---|
| RG-227U Cable | 30cm | |
| 2mm solid copper wire | 1 metre | I choose thick wire to increase rigidity and to increase bandwidth |
| Solder | As much is required | |
| Plywood 200mm x 200mm | 1 | Used to create a “jig”, to which the antenna was created. |
| Various wood pieces 40mm x 40mm x 15mm |
3 | Used to create a “jig”, to which the antenna was created. |
Design and Construction
Design is based a lot off what is described at:-
In fact, I followed it word for word, picture for picture…except that I created a Right Hand Polarized version.
