KUM121 is a high quality omnidirectional active receiving HF antenna with high dynamic range in the entire bandwidth. The antenna has a 0dB amplifier integrated, with low noise figure and diode-protection at RF and DC inputs. The KUM121 is grounded through the mounting base, so there is no requirement for AC grounding cable. It is manufactured in premium quality materials in order to prevent galvanic corrosion and has an appearance similar to the CX4 antenna.
KUM121 antenna has the same rugged design as all other AC Antennas products thus it withstands harsh environmental conditions, both on sea and land.
