KUM121 Active HF Antenna

Marine and Land Based MF/HF Active Antenna. Receive Only
Com., weather fax and positioning data. N239F. Packed in a tube
The antenna is an omnidirectional HF/SSB active receive antenna. It has an integrated
amplifier, RF and DC are both diode-protected. The high quality makes this antenna
perfect for both leisure and commercial vessels. The antenna is manufactured in
premium quality materials in order to prevent galvanic corrosion. Radiating elements are
made of copper. The antenna is manufactured using crimping technology giving the
antenna a 4-5 times stronger build-up. Fits both 1″ 14TPI and 1 1/4″ 11 TPI threads. It
has the same rugged design as all other AC Antennas products thus it withstands harsh
environmental conditions, both on sea and land
