Is there a suitable directional antenna for Groove A 52 ac?
As long as the antenna support frequency, which you want to use, it is suitable. (you didn’t say anything so I am not sure what suggestion would you expect)
After that, all you need to worry is :
- connector, but that can be easily sorted by a short cable, which you will most likely use anyway, in order to properly mount your groove vertically.
- the beam width, gain, polarization, mount type, size, weight, wind rating, power rating.. (and probably all other properties) but those depend on your application, not your device.
You don’t need to worry about manufacturer. There are no compatibility issues - antenna is simple passive device.
