En la parte de la salida falta una toma de tierra que esta en la foto del producto, no especificaron las medidas de los tornillos y son mas pequeños que los normales

After buying the Harbor Freight 2.5 Kw "inverter type" generator for ARRL Ham Radio Field Day, I found that it produced a very high amount of RF noise that would have severely hampered the operation of the radios connected to the generator. I bought this filter, placed in in a section of 3" PVC pipe for protection from the elements, and placed it the electrical line about 1 ft. from the generator. There was absolutely no generator noise heard in our radios. This filter took out the generator's normal S9 + 10 Db noise down to undetectable.

Complete waste of time and money. I have a well pump controller and 3-phase converter that causes a lot of line noise, interfering with other electronics. This device had zero effect in reducing the electrical noise or its affect on other systems.

Si estás requiriendo de un buen filtro para quitar los armónicos qué se generan por focos de balastra para quitar la interferencia este es el indicado,

A waste of money . It did absolutely nothing to stop or even slightly reduce the RFI radiated by my water pump.
