TRI7 10/15/20 is a compact size and affordable tri-band yagi. It covers the 10/15/20 meter bands with amazing performance and just one coaxial cable. On 15 and 20 meters using a reflector/driver configuration with full size components whose performance is much higher than those of the older generation antennas. On 10 meters it has 3 elements whose configuration is a reflector, driver, director. The spacings have been optimized with the latest generation of simulation software to ensure maximum performance.
Simple to assemble, the TRI 7 does not require any calibration: during assembly it will not be necessary to choose between CW and SSB. It features flat SWR below 1.5:1 on all operating bands and is a perfect fit for modern transceivers and linear amplifiers.

TRI7 10/15/20 comes with an Assembly Tool and spare parts (bolts and a pair of aluminium tubes).
The 3kW RF Choke balun is also supplied as standard. This component is very expensive and many antenna manufacturers supply it as an optional extra.
Also available with separate feeds. You can find the TRI7 10/15/20 SF in the “Separate Feeds” section.

Requires only one coaxial cable

*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.

      My TRI 7 is ten meters high and the performances are amazing. I call dxs and I receive answer from any places. Very compact antenna inside the wind and very easy to assemble. I made some contests with wonderfoul scores and results.
