This PDF document, authored by KT4QW in October 2004, details the construction and modeling of a dual-band, horizontally polarized hanging rectangular loop antenna for **10 and 17 meters**. The design, adapted from *The ARRL Handbook*, utilizes _NEC4WIN95_ software for scaling and optimization, targeting a 50 ohm feedpoint impedance. The resource includes a bill of materials, step-by-step construction instructions, and a discussion of the antenna's radiation characteristics. It presents NEC-generated elevation and azimuth patterns, comparing the loop's performance to a half-wave horizontal dipole at the same height and frequency. The 17-meter element is centered at 18.140 MHz for low SWR across the phone band, while the 10-meter element is centered at 28.500 MHz. Construction involves 14-gauge stranded copper wire and Schedule 40 PVC spreaders, with the total wire length calculated by the formula: Length in feet = 1005/MHz. The feedpoint impedance can be adjusted by modifying the rectangular aspect ratio. The document specifies hoisting the antenna to at least a half-wave above ground for testing. It notes that a balun was tested and found to have no measurable effect on SWR or radiation characteristics. A 2-meter scale model is presented to illustrate the physical design, and a "rotator" string is incorporated for directional adjustment up to 90 degrees.

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.
