Operating a G5RV antenna effectively often raises questions regarding its installation and performance across various bands. This archived discussion from the TowerTalk mailing list captures a real-world exchange, where KI0DZ shares practical insights from her own setup. She details her G5RV strung diagonally between trees, sloping from 25 feet to 10 feet, and notes its use with a Yaesu FT-757's automatic antenna tuner. KI0DZ recounts working 80 meters with 100 watts, achieving contacts up to 1000 miles, and confirms the general requirement for an antenna tuner. The thread also touches upon the G5RV's performance in an inverted V configuration, with a recommended angle of at least 90 degrees, and the ease of building one's own versus purchasing a manufactured version. While not an "antenna expert," KI0DZ's field results and direct experience provide a useful perspective on the G5RV's capabilities for "modest purposes" across multiple bands, offering practical answers to common inquiries about height, configuration, and band coverage.

If you're one of the many hams whose principal operating mode is SSB, then the easiest way to increase your enjoyment of the hobby is to use CW. If you disagree with that statement, then there's a good chance, if you're honest with yourself, that the reason is because you have never been good enough at Morse to make using it an enjoyable experience
