The VEC-820K Kit reduces noise with up to 15 dB improvement in S/N ratio -- perfect for exotic low noise operation like moon bounce. The kits 8 poles active IC filtering uses low Q cascaded stages. Stops ringing. No impedance matching needed. No insertion loss. The kit uses a 9 volt battery (not included). The kit measures 1¾ x 3½ x 3½ inches.
