Simple 2-element vertical antenna

Here’s a simple way to increase the gain of your vertical antenna.

In this video, Tim (K5OHY) shows us how to build and mount a 2-element 20 meter band vertical antenna on a wooden fence.  According to Time, this configuration produces a moderate 2.9 dBi gain over a single 1/4 wave vertical antenna.

Tim gives us a list of basic materials and procedures needed to complete this easy-to-do project.

Here are some comments from Tim (K5OHY).

Here is an update with more information on this parasitic array:    • 2 Element Quarterwave Array: 2.9dB over Si…   This is a simple 2-element 1/4 vertical using a parasitic director. CW portion of 20m: Driven Element: ~17 ft resonant at 14.05 MHz. Director: ~16.2 ft tuned to 14.75 MHz (5% higher) Radials: Two per element, 16.5 ft Spacing: 10.5 ft (3.20 m) ≈ 0.15λ at 14.05 MHz

Tim – K5OHY demonstrates how to mount a two-element vertical beam antenna on a wooden fence to overcome HOA restrictions and improve DX capabilities. This practical setup for 20 meters uses inexpensive mirror mounts to enhance signal strength toward Europe.
