What is a good antenna for tinyGS? In general, a good antenna refers to one that can get as strong signal as possible from the satellites. Unfortunately, just like fashion, there is no single antenna fits all. There are some antennas that work well in some situations and other antennas for other situations. We have not even talking about budget yet here. While there are many antennas available in the market, some people prefer to build their own antenna, either for budgetary/availability reason or for self satisfaction reason. However, you may start with the following antennas to try. Again, there is no guarantee that this will work for you but in general these are what most people are using as their first antennas: |
||
| 1. Dipole/closed dipole, a simple two elements antenna, you can build or buy: | ||

- Modified dipole from online shop (by @PeterPA3PM) https://t.me/c/1448773154/25691 (some people reported success without modification) |

2. Quarter Wave antenna (a.k.a Ground Plane) |
||
|
3. Mobile Antenna, usually a dual band 2m/70cm amateur mobile antenna |

There are many other antennas such as Yagi, Quadrifellar Helix (QFH), BiQuad (Zig Zag), Lindenblad, etc. But you may want to start with the first two above before going further. Hope this helps. #antenna #goodantenna |
