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 the elements are full size, guaranteeing a performance clearly superior to that of the old generation antennas. It will not be necessary to perform any calibration, just connect the coaxial cable and you will be ready to face the most demanding pileups. Its high performance will make the TRI12 an inseparable partner.
With its separate feed system you can operate 3 different transmitter/amplifiers at the same time! (use of BPF is necessary to protect your equipment). Suitable for multibeam/multiband stacking.

Requires three coaxial cables
Requires a rotor for medium load

RF Choke:3X 3kW included

*Wind survival is the maximum wind speed to which the antenna can be subjected without incurring permanent deformation (calculated in the absence of ice)

**The Momobeam RF Choke (standard product offering, rated at 3 KW) is made from high quality Teflon dielectric, double shielded, low loss coaxial cable with properly selected ferrite material that is sleeved over the cable that together, create a high impedance path for RF, providing high isolation between the antenna and coaxial feedline.

An SO-239 female connector is included for convenient attachment to the customer feedline and its PL-259 Male connector.

The 5 KW and 10 KW rated RF chokes (optional purchase) are made from the same materials except the coaxial cable is 10 mm diameter.

The 10KW version uses a 7/16 DIN style connector.
