Mesh RF Filters
Browse and compare RF filters for mesh networking radios. Filters knock down out-of-band noise from cellular, pagers, and other nearby transmitters before it reaches your receiver, which matters most on high-performance nodes and radios with amplifiers.
Every filter here was measured firsthand with a 2-port VNA by the Austin Mesh community: insertion loss at the Meshtastic and MeshCore US frequencies, impedance match, bandwidth, and rejection, with downloadable Touchstone sweeps. Suggest a filter here.
