DUO4 12/17 is a dualband yagi for the WARC bands of 12 and 17 meters with very compact dimensions and full size elements. The uniqueness of this antenna is that the 24 MHz driver is not directly connected, but is an “open sleeve” style feed. This greatly simplifies the assembly of the antenna. It features low SWR on both operating bands and is a perfect fit for modern transceivers and linear amplifiers.

Requires only one coaxial cable
Requires a rotor for small load

RF Choke: 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.
