How to make a quarter wave vertical 2 meter ground plane antenna.
Parts for project: http://astore.amazon.com/m0711-20?_en...
In this video I go through the build of a UHF / VHF (146 MHz) quarter wave ground plane antenna that can be used for repeater communications.

This is a simple wire antenna that makes use of a SO239 UHF / VHF connector and four radials. It is very quick to assemble with some simple tools. It is advisable to use an antenna analyzer to find the correct SWR (standing wave ratio) and resonant frequency.

This antenna also works well for receiving with a radio scanner.
