To safely connect your phone to the SDR for your TACS base station, you will need an appropriate load or attenuator to prevent damage. A typical approach is to use a 50-ohm load or an attenuator rated for the frequency range you are working with. Look for a 10-20 dB attenuator, as this should sufficiently reduce the signal strength to prevent frying the devices. Ensure that the attenuator can handle the power levels involved. It’s also advisable to double-check the specifications of both the phone and SDR to ensure compatibility. Good luck with your project! https://geometrydashmeltdown2.io
