Bicycle-Mobile antenna

Presents the design and construction details for a VHF bicycle-mobile antenna, originally published in QST. The antenna utilizes a modified Arrow J-Pole design, adapted for portable operation on a bicycle frame. Performance characteristics include a reported 1.5:1 SWR across the 2-meter band, demonstrating effective impedance matching for typical handheld transceivers.

Construction involves readily available materials, emphasizing lightweight components suitable for mobile deployment. The document provides a parts list and step-by-step assembly instructions, detailing the radiator and ground plane element lengths for optimal resonance at 146 MHz. Mechanical considerations for mounting on a bicycle are also addressed.

The resource covers practical aspects of integrating the antenna with a bicycle, including cable routing and securing methods. It offers insights into achieving reliable VHF communications while operating in a mobile, low-power environment, making it relevant for field day activities or casual portable operation.
