IBCrazy 1.3 GHz Pass/2.4 GHz Stop Notch Filter

If this made a difference it wasn't large enough for me to truly notice in my particular setup but I am using the 2.4 control right next to the 1.3 receiver. When I first put it on I did feel slightly satisfied that it didn't seem to hinder anything at least. I'm not totally sure about the design of a totally passive filter like this but it's essentially shorted via the two little punch holes. I don't know enough about such a design to know if it's supposed to be like that or not, but it's the same way in the picture so I guess so. The downside for me is that the two I bought were just easily broken as the tabs on the connectors are not very strong. Nothing wrong with the solder job just the tabs themselves on the connectors are weak. I had to make a mistake and hit the antenna against something but it was over with at that point both times. Should find a way to strengthen it if you're going to use it.

adding this notch filter to my 1.3 ghz system had little to no effect on my 2.4 ghz radio reception.

nothing to say about just it works perfect forme

Delivery time was outstanding, item is as advertised and works perfectly.
