Gpartsment

Feature:
1. AM filter circuit is fully shielded with an EMI frame, and front end is protected by ESD diodes for RF applications.
2. Made of high‑quality materials brass, resin and reinforced material, a high‑performance band‑stop filter.
3. The AM frequency provides approximately 40dB of attenuation while ensuring that adjacent frequency bands are minimally affected.
4. With frequency selection function, can filter out interference noise or perform spectrum analysis.
5. Small in size and light in weight, convenient to carry and use at any time, very convenient and practical.
