DUO9 12/17 is a dualband yagi with a single feed line for the WARC bands of 12 and 17 meters. Its performance is excellent thanks to the optimized spacing and full size elements. Simple to assemble thanks to the labeling of its parts and hardware (as for all MOMOBEAM antennas), DUO9 12/17 does not require any calibration. It features low SWR on all operating bands and is a perfect fit for modern transceivers and linear amplifiers.

*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.
