Description
motorola xtl2500. In great condition, tested and working. Come with only what is pictured Coaxial construction 50 Ω Dummy Load with N Type SocketUseful for Amateur/Ham/CB radio use and RF experiments
Brief Description
This dry dummy load has been designed to provide constant 50 Ω impedance to a radio transmitter to allow off air tests and experiments.
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 - 1.01:1
7 MHz - 1.02:1
30 MHz - 1.07:1
50 MHz - 1.16:1
70 MHz - 1.22:1
145 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. 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).
Connection to the dummy load is via a high quality N Type Connector mounted on the PCB. Overall dimensions are: 2.5" diameter, 3/4" thick (PCB sandwich, excludes N Socket)
