| USMC Antenna Handbook MCRP 8-10B.11 Of all the variables affecting single-channel radio communications, the one factor that an operator has the most control over is the antenna. With the right antenna, an operator can change a marginal net into a reliable net. Antenna Handbook, gives operators the knowledge to properly select and employ antennas to provide the strongest possible signal at the receiving station of the circuit. |

Welcome To Battery University Battery University™ is a free educational website offering hands-on battery information. The tutorials evaluate the advantages and limitations of diverse battery chemistries, advise on best choices, and suggest ways to extend life. The information is compiled from the manufacturer’s specifications, test labs and crowdsourcing. The tutorials differ from scientific papers by taking average readings because lab tests cannot always be repeated in real life. Battery University™ is sponsored by Cadex Electronics Inc |
