Note: This baby is not an antenna, it is a test instrument. If you need an antenna, please go to the store to buy it. There are dozens of antennas in the store.
The brand new export equipment has a nominal 200W dummy load. The quantity is limited, and it is no longer sold out. Using very large pure aluminum alloy heat sink. The external dimensions of the main body are about 20 * 14.2 * 6.6 cm (without joints) and the net weight is about 2.3 kg. 200W is the power for long-time continuous transmission, and the nominal is relatively conservative. Radio enthusiasts can safely use it for 0-1300W transmission test and maintenance. Because the duration of the power test used only for the radio is very short, only a few seconds. The large heat sinks have been tested before they are warm, so there is no need to worry about overheating. Comparing the 100W dummy load of Taiwan Eagle, it can be seen that the size and weight of an eagle with no egg size is actually a 15W resistor chip. The continuous average power is 15W, the instantaneous maximum power is 100W, and the continuous average power of the baby is 200W, according to Eagle's conversion method, the instantaneous maximum power is more than 1300W! Can be used for any frequency from 0-3000MHZ. It doesn't matter whether you are a handstand, a car stand, an amplifier, a repeater, a UV radio station or a shortwave radio station. The standing wave of the dummy load itself is negligible. As can be seen from the original test sweep chart, the standing wave below 500M is basically around 1.01. Thus ensuring the accuracy of the test.
The purpose of the dummy load is one of the instruments used to test the transmission power of the radio station. It is used to replace the antenna. Because the response frequency, impedance and input power of the antenna are inconsistent, it is difficult to accurately reflect the actual power of the radio station. The impedance of the entire frequency band is always constant at 50 ohms and there is a dummy load that is sufficiently resistant to incoming power to replace the antenna, so as to obtain accurate measurement data. When in use, as shown in the figure, the left input terminal (TX) of the power meter is connected to the radio, and the right output terminal (ANT) is connected to the dummy load. The load is equipped with an adapter, which can be used for N, M type radio stations, power meter connection.
In addition, the dummy load is also one of the necessary instruments for repairing the transmitter of the radio station. The radio station can be connected to the load to transmit without connecting the antenna. It will not damage the radio or radiate harmful interference waves into the air.
The power of the fake load test radio is generally equipped with a power meter. This shop has a Taiwan Nasheng power meter to form a test "golden partner". Power meters, frequency meters, and test cables are all available at our shop.
