DX Commander Signature 18 Nebula eXtreme HF Multi-Band Vertical Antennas are an excellent choice for DX performance and general operations. Efficiently resonant on every HF band of operation, featuring wide SWR bandwidth and low take-off angle, the Signature 18 covers the Amateur bands 80 to 6 meters. DX Commander vertical antennas are based on the same principles as a fan dipole, with several vertical wire elements of various resonant lengths connected to a common feedpoint. The wire elements and support ropes are arranged with spacer plates around the non-conductive fiberglass mast. When installed with an appropria
DX Commander Signature 18 Nebula eXtreme HF Multi-Band Vertical Antennas are an excellent choice for DX performance and general operations. Efficiently resonant on every HF band of operation, featuring wide SWR bandwidth and low take-off angle, the Signature 18 covers the Amateur bands 80 to 6 meters. DX Commander vertical antennas are based on the same principles as a fan dipole, with several vertical wire elements of various resonant lengths connected to a common feedpoint. The wire elements and support ropes are arranged with spacer plates around the non-conductive fiberglass mast. When installed with an appropriate radial system, the Signature 18 achieves efficient quarter-wave vertical performance with natural resonance and low SWR on every band, without the need for traps, coils or antenna tuners. Band-hopping DXing and simultaneous multi-band multiplexed operations are supported. The Signature 18 antenna is rated at 1500W SSB/CW, 400W FT8 and other digital modes.
