Vectronics DL-650MN Dummy Load


  • DC to 650 MHz
  • Impedance: 50 Ohm
  • N Connector
  • Size: 222 x 70 x 76 mm
  • Weight: 453 g


The DL-650MN Dummy Load simulates an accurate 50 Ohm antenna up to 650 MHz, enabling you to test your transmitter without radiating a signal on the air.

The Vectronics DL-650MN is a dry air-cooled resistive dummy load using a tuned hyperbolic cone that is tunable over the frequency range. This feature allows power measurement up to 1000 MHz.

This load is capable of dissipating up to 1500 watts average from DC to 650 MHz. A reasonable cooldown period is needed to keep the resistor from becoming permanently damaged. (Typically 10 – 20 times the load usage.)

Key features:

  • DC to 650 MHz
  • Handles short-term RF power up to 1500 W
  • Voltage gradient: 10 kV per inch
  • Resistor type: Dispersed carbon particles fired in ceramic matrix
  • Energy density: 700 joules per cubic inch
  • N Connector
