What is the best low frequency antenna I can get?
I was working with this antenna:
and I can get the 1km distance they promised, but it got to be air distance. If I have one building in the way than it goes down to maybe 100 meter distance.
So I was recommended to use low frequency antenna. What is the best I can get?
Could you describe your use case? There might be other solutions that are useful. Repeaters or LoRa for example.
I'm planning on using it inside a greenhouse sending on/off signals.
I've got a pretty bad reception trying it inside the greenhouse. maybe because of the humidity...I don't know.
I thought about using repeaters but before I do, I want to try using different radio...
What distance I can get with the 433 MHz..?
@mk55 the range will depend on a lot of factors, but my google search results say 350-2400m.

Is it possible to get solderless rfm69 with sma antenna like the nrf?
Thanks for your help.
