Features: 1. Small size, light weight, low insertion loss, frequency can be customized. 2. There are gold-plated SMA connectors on both sides (one side is SMA female connector - external threaded inner hole; the other side is SMA male connector - internal threaded internal needle), double-sided circuit board design, high mechanical strength and stable electrical performance. 3. It has good passband ripple coefficient and out-of-band suppression capability. 4. Unique shielding design, beautiful and practical. 5. patch components, and zero failure rate. FOR Dedicated FPV aerial photography drones, etc. 1.4G low-pass filter. Effectively reduces the interference of 1.2G image transmission on 2.4G equipment (2.4g remote control receiver) and increases the remote control distance! Connected to 1.2g image transmission, it can greatly reduce frequency interference above 1.4g If your image transmission is 1.2g and the remote control receiver is 2.4g, then this filter is highly recommended. Under the same conditions, the transmission distance and anti-occlusion performance of 1.2G image transmission are much those of 2.4G and 5.8G image transmission, making it more suitable for video transmission over long distances and complex environments. Note: This filter is only suitable for image transmission at frequencies below 1.4G, not suitable for 2.4G and 5.8G image transmission! Due to different batches, the appearance, color, and printed words of the product may be different, which does not affect the use. size: 35mm x 7mm x 6.5mm Material: Metal colour: Silver+gold Package Contents: 1 x Low Pass Filter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
