TETRA14 10/15/20/40 Separate Feed is a multiband yagi with a super compact design and unique features. We often see towers full of very close spaced monoband antennas. Do you think this is the best solution? Towers full of antennas inevitably interact that distort the radiation patterns.

With the TETRA14 Separate Feed this problem is overcome!
In fact, each band has its own feed connection, allowing contest stations to use this antenna simultaneously with 4 different transceiver/amplifier setups, as if each station had their own monoband antenna (use of BPF is necessary to protect your equipment). As a result, the space occupied on the towers is significantly reduced and performance is also significantly higher!

On TETRA14 Separate Feed the spacing of the elements has been optimized through the latest generation software to ensure the best performance.
On 40 meters it has two elements with a Reflector/Driver configuration, whose size has been compacted using loads placed at the ends. This solution, which was originally adopted by W6NL, to which our thanks go, allows the performance to be like a full size yagi although it has a reduced element length. On 10/15/20 meters, it uses 4 elements per band with reflector, driver and 2 directors configuration.


TETRA14 10/15/20/40 Separate Feed comes with an Assembly Tool and spare parts (bolts and aluminium tube).
N.4  3kW RF Choke balun is also supplied as standard. This component is very expensive and many antenna manufacturers supply it as an optional extra.

Simple and intuitive assembly – TETRA14 10/15/20/40SF use square boom. All hardware is supplied in separate, labelled bags and all aluminium tubes are labelled to make assembly quick and easy!

Requires four coaxial cables, one for each band
Requires a rotor for medium/heavy load

RF choke:4X 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.
