I wanted to get some baseline measurements before I replaced my antenna for a removable one.
It’s just comparative reference plots, so don’t expect absolute values with quotable numbers. I will return to this for more measurements, but have to get back to balsa building while I wait for my DigiKey order
In comparing the Taranis to Hitec, which I always thought well of in regard to their RF link, I’m happy to see the Taranis has at least or better peak power, but it’s TWICE the bandwidth as Hitec. This could be good or bad depending on your application.
First pic is the quick and dirty setup with each transmitter antenna exactly12″ from the analyzer antenna. I also swapped transmitters around and saw no measurable difference. Plots are labeled.
You can see how the LR12 mode gets better range. I haven’t measured the timing yet (as I only wanted an RF reference) but explained simply,
If I’m yelling at you from very far away, you can understand me better if I talk slower. LR12 is less data at same power.
Added a plot showing the difference between Americas and Europe RF settings. I can’t see any. I truly don’t know if the specs or regulations are different.
