TETRA18 10/15/20/40 DUALFEED

TETRA 18 10-15-20-40 DUALFEED is a high performance and versatile quad-band Yagi. Can be installed on large towers with sides up to 150 cm.

On 40 meters it has a Reflector / Driver configuration and the size of the elements has been compacted using loads placed at the ends of the elements. This solution, which was originally adopted by W6NL, allows you to maintain the performance of a fullsize by limiting antenna dimensions.
On 10/15/20 meters it features fullsize elements and a classic configuration: 4 elements in 20, 5 elements in 15 and 7 elements in 10 meters

No traps or other adaptation systems have been used on this antenna, nor are there any moving parts: no motors or relays that risk breaking! There are virtually no limits to the applicable power. Only reliable and durable aluminum!

TETRA 18 10-15-20-40 DUALFEED 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 (requires additional BPF to protect your equipments)

Suited for 150cm tower lift
Requires 2 coaxial cables
Requires a rotor for a heavy load
