TRI7 101520 is a compact and affordable triband yagi antenna.
It covers the 10-15-20 meter bands with surprising performance and a single coaxial cable.
On 15 and 20 meters, it uses a reflector/radiator configuration with full-size elements whose performance is significantly superior to those of old-generation antennas. On 10 meters, it features 3 elements in a reflector, radiator, director configuration.
Spacing has been optimized with state-of-the-art simulation software to ensure maximum performance.
Simple to assemble, the TRI 7 does not require any tuning: during assembly, there will be no need to choose between CW and SSB.
It features a flat SWR below 1:1.5 on all operating bands and is perfectly suited for modern transceivers and linear amplifiers.
Also available with separate feeds. You can find the TRI7 101520 SF in the "Separate Feeds" section
Suitable for crank-up towers with 130cm side.
Requires a medium/light duty rotator.
