Description:
Kit form. Low noise preamp, covers 1-30 MHz (approx.). The W7IUV design is a long-time standard, but MTM notes "The [published] plans emphasize the importance of using specific parts, which can be expensive and time consuming to gather. The MTM kit contains the correct parts and also includes a circuit board to simplify construction and create a nice finished project."

Works fine but BNC connectors weak Time Owned: 0 to 3 months.
I bought the kit to work with an HF portable flag antenna for direction-finding. It only took about an hour to assemble, and worked fine at first, but the first time I took it out in the field, both BNC connectors broke loose. The problem is that they are only physically attached by the center conductor, and their ground connection is through a thin wire attached to the connector by a nut. I replaced the connectors with appropriate surface-mount units with three physical mounting tabs. Just plan on doing this if you get one.
