5.8GHz antennas measured

I always wonder, how different are all the antennas you can but on banggood, or aliexpress, and finally i can check it using my simple sweep analyzer.

That’s all I found in my drawer, including my very fist DIY helical antenna.

First I used 50 ohm dummy load to determine error which is of course not zero because VTX produce different RF output depending on frequency, and directional coupler is not ideal 🙂

Next i measure all the antenna, correct measured values, using previously determined error values.

Te results look like following.

  1. Hi Kris, thank you for the measurements. Can you please denote the tested antennas somehow? For example, it is not clear which Realacc is which.
