Is this antenna compatible with this lora module?

I just want to make sure, the wavelength is the same, but maybe there are other parameters that are important.

Yes, these are 1/4 wavelength "whip" antennas

If they are what they say they are.

To me those look way too short to be a 1/4 wave at 433Mhz.

They look more like the size of a typical 2.4Ghz antenna.

There is nothing 'special' about an antenna for a LoRa device, but the frequency has to be right.

The U.FL connectors often break after just a few connect/disconnect operations. They are for semipermanent installations only.

I am planning on installing them permanently.

Thank you for the answers!

if you want to limit the range of your lora, you bought the right antenna. when you need more range, step up to

5 db gain antenna or start looking at ham radio DIY pages.

Hi,
Have you checked what LORA frequencies you can use in your country?

It seems in Europe you can use 433 Mhz.

The regulations in most all places in the World do not specifically give or deny permission for LoRa, it is propriarty modulation anyway, specific to Semtech.

The Things Network, TTN, that uses LoRa, is in use in most place in the World;

TTN Map

What you do need to check, for your part of the World, is that the frequencies, transmit power, bandwidth and duty cycle your using are permitted.

The SX127X series LoRa devices are normally used at bandwidths of 62500hz or 125000hz and in some places this can restrict you to 10% or even 1% duty cycle.

The newer SX126X series LoRa devices will operate reliably at bandwidths right down to the LoRa modulation minimun of 7800hz, this can allow you to operate at 100% duty cycle.

It all depends where you are ......................

it's called an ISM band. what is permitted where: ISM band frequency allocations

the USA has Part 15, with many bands available: Part 15 per the FCC

you need the mind of a Beverly Hills divorce lawyer to understand the rules.

Hi,

In Australia, The Things Network uses both the LoRaWAN AU915 band plan and (more recently) the AS923 bandplan.
Basically to try and keep Lorawan in some sort of order.
