The MFJ-862 Cross Needle SWR/Wattmeter is a versatile and powerful tool designed for amateur radio operators working in the 144 MHz, 220 MHz, and 440 MHz bands. With a power range of 30W to 300W, this device is capable of handling a wide range of transmitter outputs, making it an ideal choice for both novice and experienced users.
The MFJ-862 features a cross needle SWR meter, which allows users to easily and accurately monitor the standing wave ratio (SWR) of their antenna system. The SWR meter has a scale that ranges from 1:1 to 20:1, providing a clear and easy-to-read indication of the antenna's efficiency. The wattmeter function, on the other hand, allows users to measure the actual power being delivered to the antenna, which is crucial for optimizing transmitter performance and minimizing power loss.
The MFJ-862 is also equipped with a built-in RF amplifier, which enables it to provide accurate readings even in the presence of strong RF signals. This feature is particularly useful in crowded frequency bands, where interference from other stations can make it difficult to obtain accurate readings.
The MFJ-862 is built to last, with a rugged aluminum housing that is resistant to damage and corrosion. It also features a backlit LCD display, which makes it easy to use in low light conditions. The device is powered by a 9-volt battery (not included), and has a convenient on/off switch to conserve battery life when not in use.
Overall, the MFJ-862 Cross Needle SWR/Wattmeter is a reliable and powerful tool for any amateur radio operator looking to optimize their antenna system and maximize transmitter performance. Its versatile power range, accurate SWR and wattmeter readings, and rugged construction make it a great choice for users working in the 144 MHz, 220 MHz, and 440 MHz bands.
