Avionics TDR


The Avionics TDR and TDR Avionics Kit are designed specifically for testing and fault location on aircraft wiring. Both models have been upgraded to include military grade RF shielding and explosion proof TDRs. The Step TDR is ideal for troubleshooting all types of coax, twisted pairs, single-wires in a harness, and aircraft power cables.

Whether you need cable or antenna testing, coil tuning or a fault finder, we've got a product that will get you taken care of and solve your cable problems.
