This article discusses the design and implementation of a 2-element wire beam antenna for the 20 meter band, suitable for field day operations with 4 Switchable Directions. The antenna is configured with sloped wires in an inverted V shape, with a specific design to achieve directional properties. The author tested the antenna design using MMANA and NEC2 software, based on a solution published in QST. Detailed diagrams and instructions are provided for constructing the antenna on top of a 12 meter mast, with specific wire lengths and positioning to ensure optimal performance. This resource is valuable for hams looking to build a directional antenna for the 20m band and improve their field day setup.

This paper presents an 80 meter wire 3-element beam antenna in an inverted-V configuration, designed for limited-height towers. Using EZNEC modeling, the antenna features a central parasitic reflector and two switchable driven elements at each end, enabling NE/SW coverage without moving parts or networks. Element lengths are optimized for SSB (3.8 MHz) and CW (3.5 MHz) operation, with a 50 Ω feed and rope-supported boom. The design delivers high gain, effective takeoff angles, and excellent reception, confirmed in real-world DX contest operation. Its simplicity, reliability, and ease of construction make it ideal for operators seeking performance without complex matching systems.
