Why Choose Our Cavity Filter
Our cavity filter is fully optimized for the helium network and attenuates other frequencies a lot (more than 30 dB). Because this cavity filter has more cylinders, it offers a better signal loss compared to the other cavity filters available for the helium network. Also the way the cylinders are connected the filter will now act as a lightning arrester as well. This will help you gain 3 dB since the lightning arrester has a 3 dB signal loss which is equal to missing a potential of 100 hotspots signals.
Military-Grade 868Mhz Optimized Helium Cavity Filter
This ultra high performance military grade cavity filter, with a maximum 0.5 dB signal loss at its peak performance 868Mhz frequency, it is perfectly suited for the helium network and is vastly superior to the simple surface acoustic wave (SAW) filter. Resulting in a significant change in receiving power, up to 50% more and therefore earning a lot more HNT. With its solid black case and N female connectors it can handle all weather types without any problem.
