Coaxial construction 50 Ω Dummy Load with SO-239 UHF Socket<br>Useful for Amateur/Ham/CB radio use and RF experiments<br>Brief Description<br>This dry dummy load has been designed to provide constant 50 Ω impedance to a radio transmitter to allow off air tests and experiments.<br>The coaxial construction creates a load that presents a more stable resistance to the transmitter output over a wider range of<br>frequencies, testing has shown the following SWR measurements using a RigExpert AA-230 Zoom, +/-:<br>3.8 MHz  - 1.01:1<br>7 MHz     - 1.02:1<br>30 MHz   - 1.07:1<br>50 MHz   - 1.16:1<br>70 MHz   - 1.22:1<br>145 MHz - 1.60:1<br>Constructed from high quality PCB material and using 20 x 1 KΩ 3 Watt Metal Film or Carbon Film resistors (see photos)<br>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. The load can also be mounted in a can with oil for longer use at 100 watts. Mounting holes in the PCB can accommodate 4/40 bolts that will allow the load to be mounted on a can lid. Some details on how to do this are in the user guide (available on request prior to sale if needed).<br>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)<br>Please also see the photos as these are part of the description<br>What's<br>included for Sale?<br>1.
