2. Safe for Transmitters: It protects the transmitter from damage by absorbing any reflected power that could potentially harm the transmitter.
3. Helps in Tuning and Testing: The RF bird can be used for tuning and testing transceivers, antennas, and other RF equipment.
4. Durable and Reliable: The 8200 series from MFJ is known for its durability and reliability, making it a good investment for long-term use.
5. Versatile: The 8201 model can handle up to 500 watts of RF power and can be used for various frequencies, making it a versatile tool for ham radio operators.
Cons of buying a 500Watt 8201 Ham Dummy RF Bird:1. Expensive: Compared to other RF loads, the 8201 is quite expensive.
2. Bulky and Heavy: Due to its size and the materials used, the RF bird is quite heavy and bulky, making it difficult to transport.
3. Requires Space: The RF bird requires a significant amount of space, which might be a constraint for some ham radio operators.
Ending Conclusion:The 500Watt 8201 Ham Dummy RF Bird is a valuable tool for ham radio operators, especially those who use high-power transmitters. It offers numerous benefits such as improving transmitter efficiency, protecting the transmitter, and aiding in tuning and testing. However, its high price, bulkiness, and space requirements are significant drawbacks.
Recommendation:If you are a serious ham radio operator with a high-power transmitter and the necessary space, the 500Watt 8201 Ham Dummy RF Bird is a worthwhile investment. However, if you are on a budget or have limited space, you might want to consider other, less expensive and more compact RF loads.
The resistor, individually selected for its accuracy, is enclosed in a special tapered housing which provides a linear reduction in surge impedance directly proportional to the distance along the resistor. The load consists essentially of a cylindrical film type resistor immersed in a dielectric coolant.
