Depending on the location/reception strength or the power adapter used, it may happen that the Boomster has poor to no DAB+/FM reception while operating on mains power.
Quick Tips for Better Reception
First, try these simple measures:
✅ Position the antenna as far away as possible from the charging cable and power supply.
✅ Avoid the antenna and charging cable crossing or touching each other.
✅ Remove objects in the immediate vicinity of the antenna.
✅ Test different antenna lengths to find the optimal position.
✅ Use a high-quality USB-C Power Delivery power supply that meets the requirements of the BOOMSTER 4.
Wrapping the USB-C Cable
This method can reduce interference and can be implemented without additional accessories.
How it works
- Wrap the USB-C charging cable tightly 4 to 5 times at both ends.
- The coil should be about 3 to 4 fingers wide.
- Secure the coils with cable ties if necessary.
Advantages
- No additional accessories needed
- Quick and easy to implement
Please note
- Wrapping shortens the usable cable length.
- If the improvement is only slight, increase the number of wraps and ensure the winding is as even as possible.
Using Ferrite Cores
Ferrite cores can reduce interference particularly effectively and often provide the best and most reliable improvement.
How it works
- Attach one ferrite core at the beginning and one at the end of the USB-C charging cable.
- Wrap the cable 2 to 4 times through the ferrite core.
- Ensure the winding is as even as possible.
Advantages
- Especially effective
- Minimal shortening of usable cable length
- High reliability
Please note
- Ferrite cores are required for this solution.
- If the improvement is only slight, increase the number of wraps.
