C3VR Vibration Resistant Crystral

Today’s communication devices require a clean and stable frequency source, which is not hard to find (at Fox), but what happens when a train or large truck goes by the 5G base station?

The resulting vibration is an acceleration event that can create a frequency shift in your otherwise stable source. To combat this, before resorting to bulky vibration isolators, you can minimize noise due to vibration by using the C3VR Crystal from Fox.
