TETRA15 10/15/20/40 DF


TETRA15 10/15/20/40 DUALFEED is a multiband hf yagi with a super compact design. On 40 meters it has a Reflector/Driver configuration and the size of the elements has been compacted thanks to loads placed at the ends of the elements. This solution, which was originally adopted by W6NL, allows you to maintain performance from fullsize by limiting its dimensions. On 20 meters, it uses full size elements with reflector, driver and director configuration. On 15 and 10 meters, the four (4) active elements are configurated as a reflector, driver and two directors. Dual feeding lines allows contest stations operate on two bands simultaneously and enjoy monoband performance at each station (use of BPF is necessary to protect your equipment).


TETRA15 10/15/20/40 DUALFEED comes with an Assembly Tool and spare parts (bolts and a pair of aluminium tubes).
N.2  3kW RF Choke balun is also supplied as standard. This component is very expensive and many antenna manufacturers supply it as an optional extra.

Requires 2 coaxial cables: one feeds the 40 meter band and the other feeds the 10/15/20 meter bands
Requires a rotor for medium/heavy load

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.
