The TECHOMAN TM-D3000N Super Discone is an ultra-wide band antenna identical to the Diamond D3000N and capable of covering 25 MHz to 3000 MHz continuously plus 20 metre ultra low loss feed coaxial cable.
The exceptionally versatile frequency range of 25 - 3000 MHz is due to its concept, design and quality build. This wide frequency range makes it the perfect wide-band antenna for all popular uses, such as: Scanner Receivers, Amateur Operators, CB'ers, VHF and UHF Commercial, Aviation Air Band, VHF Marine, ISM, Cellular users and more ...
Rust-free stainless steel is employed in major component parts making the antenna rust resistant and durable.
Easy to assemble, requiring only one Allen key (provided) with 2 support brackets for pole mounting, together with U bolts to allow mechanical mounting onto a vertical pipe up to 50mm diameter. Made of stainless steel, chromed brass and anodized aluminium to guarantee the best efficiency and performance these antennas are made to perform!
