The Diamond D130J is a professional-grade, ultra-wideband discone antenna engineered to deliver outstanding omnidirectional performance across an exceptionally broad frequency spectrum. Designed primarily for wideband monitoring, communications, and scanner installations, it offers continuous reception capabilities from 25 MHz up to 1300 MHz. This makes it an invaluable asset for amateur radio operators, broadband scanners, aerial monitoring, and commercial communication networks requiring reliable signal interception in all directions.
In addition to its class-leading reception bandwidth, the D130J supports multi-band transmission on several key amateur bands, including 50, 144, 430, 904, and 1200 MHz. The antenna is constructed from premium stainless steel, providing superior mechanical strength, corrosion resistance, and structural stability against harsh meteorological conditions. It measures 1.7 meters in total height (including the top vertical whip element) and features an integrated SO-239 (UHF female) RF connector base, safely handling power levels up to 200W FM on frequencies above 140 MHz.
