This instructional booklet from 1947, published by the National Radio Institute, teaches technicians how to select and install various radio antenna systems. It details the differences between inverted L and doublet antennas, emphasizing their use in remote areas or locations with high electrical interference. Readers are guided through safety protocols, such as installing lightning arresters and obtaining permissions, as well as the mechanical aspects of building wooden masts and securing wires. The text also covers indoor alternatives for restricted spaces and provides troubleshooting methods using voltmeters and ohmmeters to identify defects. Ultimately, the manual serves as a practical guide for servicemen to improve broadcast reception and generate additional income through professional installation.
