DUO5 30/40T SF is a spectacular dualband yagi for the 7 and 10 MHz bands with incredible performance. On 30 meters it has three full size elements with Reflector/Driver/Director configuration; on 40 meters it has two elements with a Reflector/Driver configuration with compact size using loads placed at the ends of the elements. This solution, which was originally adopted by W6NL, allows to maintain the performance of a full size by reducing the size of the elements. Consequently, the performance of this antenna is comparable to a fullsize and both bands are fully usable with SWR below 1.5:1 on over 200 kHz.
It will no longer be necessary, during installation, to choose the portion of the band for which to optimize the antenna (typical characteristic of antennas with coils). You will have top performance!

Requires two coaxial cables
Requires a medium / heavy duty rotor

RF Choke:2X 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.
