TETRA 15 10-15-20-40 DUALFEED is a multiband yagi with a super compact design.

In 40 meters it has a Reflector / Driver configuration, 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 fullsize performance while limiting its size.
On 20 meters it uses the reflector, driver and director configuration, while on 15 and 10 meters there are 4 active elements in the reflector, driver and two directors configuration
The antenna requires 2 coaxial cables: the first feeds the 40 meter band and the second feeds the 10/15/20 meter bands.
The dual power supply allows contest stations to use this antenna as a multi/monoband: while one RTX transmits on 10/15/20 meters, a second RTX can operate simultaneously on 40 meters.

Suitable for trolley trusses with 70cm sides
Requires a medium/heavy load rotor

RF choke: 3kW included

Availability: Usually delivered within 2/3 weeks
