Coaxial construction 50 Ω Dummy Load with SO-239 UHF Socket and Voltage Measuring Port. Useful for Amateur/Ham/CB radio use and RF experiments Brief DescriptionThis dry dummy load has been designed to provide constant 50 Ω impedance to a radio transmitter to allow off air tests and experiments. Additional functionality is provided by the measuring port that allows transmitted voltage to be measured and the result used to determine power levels. The coaxial construction creates a load that presents a more stable resistance to the transmitter output over a wider range of frequencies, testing has shown the following SWR measurements using a RigExpert AA-230 Zoom, +/-: 3.8 MHz – 1.01:17 MHz – 1.02:130 MHz – 1.07:150 MHz – 1.16:170 MHz – 1.22:1145 MHz – 1.60:1 Constructed from high quality PCB material and using 20 x 1 KΩ 3 Watt Metal Film or Carbon Film resistors (see photos) the dummy load while air cooled is capable of absorbing RF energy of 40-50 Watts continuously for 1 minute, and up to 100 Watts for several seconds. While the load can also be mounted in a can with oil for longer use at 100 watts, the presence of the measuring port terminals will mean some extra steps or openings in the can will be required. Connection to the dummy load is via a high quality SO-239 UHF Connector mounted on the PCB. Overall dimensions are: 2.5″ diameter, 3/4″ thick (PCB sandwich, excludes SO-239). Voltage port is via red and black eyelet connectors, suitable for attaching a multimeter to for voltage measurement. Calculations for converting voltage to power are shown in one picture here and included in the user guide. Please also see the photos as these are part of the description. Note: Resistor color may vary depending on supply source. What’s included for Sale?1. Fully assembled Load PCB as per above description and photos2. Quick start guide3.
