A satellite antenna can be made from 3 mm copper or aluminum elements, PVC boom, and some parts you may already have at home. To download the plan (highest-resolution), click here.
1. All measurements are in millimeters (mm).
2. Use 3 mm copper or aluminum elements.
3. Adjust the critical gaps for lowest SWR (adjust the 14 mm and 22 mm gaps as needed).
4. Only the VHF elements (Moxon part) are connected to the feedline. The UHF element (325 mm) closest to the feedpoint is the UHF driven element. It is not connected to the feedline, but resonates only when the proper gap is achieved.
5. The feedline connects directly to the radio (no diplexer/duplexer needed).
6. Use translucent plastic insulator from an RG8 cable for the 14 mm Moxon gap
7. Use non-metallic boom (wood or orange PVC pipe).
8. The feedpoint gap is 10 mm.
9. The antenna works with any dual-band UHF-VHF radios
