TRI10 10/15/20 is the much loved medium-sized triband yagi with exciting performance and a very attractive price. It covers the 10/15/20 meter bands using a single coaxial cable. On 15 and 20 meters it has 3 full size elements per band, with the reflector, driver and director configuration. On 10 meters it has 4 elements whose configuration is reflector, driver, and two directors. Simple to assemble, the TRI10 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.

TRI10 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.

*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.

      I want to say that antenna (TRI10) is AWESOME! It construction is first rate and performs even better. SWR is perfect across all 3 bands. I have it at 15 meters up. Purchased from USA supplier HRO.
      In WPX CW 2023 I easily cruised to a SOAB LP TS victory in USA, all because of this antenna. So, if you hear WC4E / N4AO in a contest, it’s this antenna!

      I highly recommend this antenna! I’m thinking about getting another TRI10!
