DUO4 12 17 is a dualband yagi for the WARC bands of 12 and 17 meters with very compact dimensions and full-size elements.
The peculiarity of this antenna is that the 24 MHz driver is not directly connected, but is of the "open sleeve" type. This greatly simplifies the antenna assembly.
It has a low SWR on all operating bands and is perfectly suited for modern transceivers and linear amplifiers.
The DUO4 12 17 can be installed on large towers with sides up to 250 cm
Requires only one coaxial cable.
Suitable for crank-up towers with 180cm side
Requires a rotor for a small load
RF choke: 3kW included
