EM-M10003-GPI - EM Wave UHF 2dBi Gain Roof Mount Antenna 380-520 MHz w Spring GPI

EM-M10003-GPI - EM Wave UHF 2dBi Gain Roof Mount Antenna 380-520 MHz w Spring GPI -- Overall Length 16.125" - The EM-M10003-GPI is E/M Wave, Inc's new 1/2 Wave Ground Independent, Wide Band Antenna (GPI). This antenna has Stainless Steel Springs for enhanced durability and mechanical flexibility and is specifically designed for optimal “wide band” VSWR performance and specifically designed for applications where a ground plane is not available such as fiberglass or other polymer/plastic mounting surfaces. Other mounting applications include mirror mount or small “L-brackets” mounted to mirrors or offset mounted to vertical poles/masts. Typical applications would be fiberglass roof top installation found on commercial buses and trucks with non-metallic cabs or extended rear-view mirror brackets found on most trucks and commercial/industrial vehicles. Typically, a VSWR performance of 1.5:1 is achieved for the GPI installation. Additionally, the antenna will also provide wide band performance when mount
