An effective filter Review by KGJones
Overall Rating
I'm a ham radio operator living about 200 feet from neighbor who is operating a 1 KW electronic grow lamp ballast 12 hours per day. The ballast and lamp radiate a signal reading higher than S9 on my receiver, completely blanking out all signals on the 40 meter amateur band. In desperation I purchased one of these filters and gave it to the neighbor. It dropped the interference level around 35 decibels to about S3. I donated another filter I had lying around, this one designed go between the ballast and the power line. That dropped the interference level to below S1. This filter is quite effective, especially when used in conjunction with a power line filter installed between the ballast and the power mains. (Posted on 1/27/2016)
filter works well Review by kgjones
Overall Rating
I am an amateur radio operator living in close proximity to a neighbor who has been operating a 1 KW electronic grow light ballast. The resulting EMI was completely destroying my 40 meter short wave reception. Adding this filter knocked the interference down about 36 decibels, which amounts to 6 S-units. The interference went from over S-9 down to S-3 or 4.

With the addition of a power line filter to the ballast input the EMI was reduced another 2 S-units. I recommend this filter, but in severe cases adding a second line filter to the system (different kind of filter than this) would be desirable. (Posted on 1/21/2016)
