Antenna
3 of 7
The antenna is a homebrew 1/4 wave groundplane vertical mounted 40 feet off the ground atop a building. It's fed with RG-8/U coax. The antenna is constructed from a 57-inch piece of 3/8 inch aluminum rod (driven element) threaded into a mobile antenna mount on a 5-inch piece of 2 x 2 inch aluminum angle stock. The three radials are 60-inch pieces of 1/4 inch aluminum rod threaded and mounted to the angle stock with stainless hardware. The antenna has a VSWR of less than 1.5 across the 50-51 MHz band segment.
