• KK5BL How To Build A G5RV Antenna - How to build a G5RV Transmitting antenna Originally posted to the packet bbs system by KC6CFF. The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands are covered, including 30, 17, and 12. The G5RV has high SWR, by design, on most bands and a tuner is required

• WW2Y/K2WI Beverage design - Ideas for enhanced beverage antenna performance, Single wire beverage improvements and arrays of two beverages. This article explores improving reception with Beverage antennas. It discusses single wire Beverages and their limitations. Then it compares two array configurations: broadside and end-fire. Broadside offers better front-to-side ratio but requires more space. End-fire offers better front-to-back ratio and takes less space but is trickier to implement for multiple bands. The article concludes with a 3-element end-fire design for excellent performance and explores possibilities for dual-band configurations.

• Nec2Go - Powerful antenna modeling tool using NEC 2 computing engine. Nec2 specifically provide users, either those experienced with the Nec2 processes, or for those who are neophytes but want to model their own antennas. Nec2Go uses a simplified process for defining the antenna structure and then providing view of the structure, plots (2D and 3D) and other significant data that is pertinent to the design. This simplified process uses an edit file with equations for all definitions.
