NOOB antenna help needed

Post by studysession » Fri Aug 10, 2018 10:52 pm

I have a couple of dongles. Trying them on both Windows 10 and Raspberry Pi. I am new at everything.

I bought this case to easily mount in my pickup if I want to go mobile and will provide cooling and protection to the raspberry pi device

I see some antennas for specific frequencies and that is where I am really over my head. This case designed for air plane stuff which is cool but I am just using it because of the case.

Than setup usually used for the case with the dongles flashed for airplane stuff but I am not using are these

Those are the styles of antennas I want but not to a specific frequency. Is it the antenna or the dongle that is tied to the frequency?

If it is the dongles I found the antennas separately here

But they are marked with specific frequencies. As stated before that is the style of antennas I am looking for and do not know enough to know what to buy.

Thank you
Keith

The dongles can be used for any frequency, it's the antennas that are tuned for specific frequencies. The antenna size is linked to the optimal frequency that it can receive at. Those antennas you linked are sized optimally for 978 MHz and 1090 MHz.

If you want to receive other frequencies you should find an antenna sized properly for that frequency, or just buy a wideband antenna like a discone, although those aren't going to fit nicely on the case. Alternatively, find a telescopic antenna that can fit onto the case, as those can be adjusted to be optimal for many frequencies.

For the nano dongles, instead of the Nooelec ones, i'd recommend buying the Stratux ones. Although the Stratux ones are intended for aircraft ADS-B, they're still RTL-SDR dongles, and hence can receive on any frequency supported. The Stratux ones seem to be much better as they have lower noise and run cooler.
