All-Copper J-Pole Antenna Construction for 2 Meters

This resource details the construction of an all-copper J-Pole antenna for 2-meter operation. The design addresses issues of dissimilar metal corrosion and coaxial feed line deterioration observed in previous aluminum J-Pole builds. The methodology involves using rigid copper tubing and fittings, with all connections soldered to ensure electrical integrity and weatherproofing. The antenna is designed for VHF base station use and can be assembled within approximately one hour. Materials consist exclusively of copper and brass, eliminating galvanic corrosion. The document provides a detailed parts listing in Table 1, specifying copper tubing lengths and other hardware. The antenna is dc-grounded, removing the requirement for insulating materials. The total material cost is stated to be under $15.
