Hi All,
I am working on a project (weather station) and will be using an HC12 as the sender from the remote unit to the inside unit.
Currently in my tests I am receiving good communication through approximately 20m of brick walls and plaster etc.
When the remote module is finally mounted up the pole the inside unit will be approximately 30m from the remote and have to transmit through roof tiles, walls etc.
The HC12 has a small connector that looks like the laptop wifi antenna connector so I assume it is for an external antenna.
I did a Google search for 433mhz antennas and there is a huge range of prices and types so I thought I would consult the oracles on TBS.
So Oracles,
What are you using for external antennas for the HC12?
And
Would I need this external antenna for both the sender and receiver or will having one installed be sufficient.?
Kind Regards,
Mick
