A Preamp for Dynamic Mics, An Easy Mobile Support Mount, and More

摘要

I needed an inside wall bulkhead plate for coax that could accommodate several connectors, as well as connect the station grounding conductor to the external ground system. While perusing the local hardware store, I came across a 10 x 4 x 0.025 inch copper plate that seemed like a possibility, especially because it meant there'd be no cutting or bending involved.
