VHF Dipole Antenna Specs 48-250MHz

This document provides specifications for a VHF center fed dipole antenna for use in various frequency bands between 48-250 MHz. The antenna can be configured for vertical or horizontal polarization. Multiple dipoles can be stacked and phased to form an array with higher gain. The antenna is robustly designed to operate reliably in harsh environments. It comes with mounting bracket options and specifications for electrical performance, materials, dimensions, weight and wind load.
