TRI12 10/15/20 SF is a fantastic medium-sized triband yagi. It covers the 10/15/20 meter bands with extraordinarily low SWR without using traps or tuning systems. All elements are full size, ensuring significantly superior performance compared to older generation antennas. No calibration will be necessary, just connect the coaxial cable and you'll be ready to face the most demanding pileups. Its high performance will make the TRI12 an inseparable partner.
With its separate feeding system, you can operate 3 different transmitters/amplifiers simultaneously! (the use of BPF is necessary to protect the equipment). Suitable for multi-beam / multi-band stacking.
Requires three coaxial
cables Requires a medium-duty rotor
RF Choke: 3X 3kW included

*Wind survival is the maximum wind speed that the antenna can be subjected to without permanent deformation (calculated without ice)
**The Choke RF Momobeam (standard product offering, rated at 3 KW) is made with high-quality, double-shielded, low-loss Teflon dielectric coaxial cable with properly selected ferrite material that is coated on the cable, which together create a high impedance path for RF, providing high isolation between the antenna and the coaxial feed line.
An SO-239 female connector is included for convenient connection to the customer's feed line and its PL-259 male connector.
The 5 KW and 10 KW rated RF coils (optional purchase) are made with the same materials, except that the coaxial cable has a diameter of 10 mm.
The 10KW version uses a DIN 7/16 style connector.
