Carbon Composite Resistor of proper impedance to match antennae and high
enough wattage to dissipate total wattage output of the device. Wattage
should be plus 10% for safety reasons. I.E 50 Ohm 5 Watt I personally would
use a 7.5 or 10 watt carbon resistor at 50 ohm DC Resistance. Connect the
resistor directly to a antennae plug that connects to the device under test.
