RQ-84 – the classic “Quad” full-size has ten elements for 10m, eight – 15 m, six – 20 m, and four full-size elements on 40m band. The antenna has a 21 m boom, diameter – 100 mm.
RQ-84 – the largest and most effective antenna R-QUAD on 10, 15, 20 and 40 m bands.

Depending on the type of rotary device used to rotate the RQ-84 (must be reported when ordering), the antenna can be equipped with attachment unit on the vertical pipe. Boom in two planes stretched three rows of stretch aramid rope diameter of 6 mm. Each spreader length 7.8 m stretched two levels of aramid rope 2 mm or galvanized steel wire of 1.6 mm diameter with insulators (specified when ordering).
Antenna RQ-84 is packed in four cardboard boxes the size 160x160x2000 mm and two 160x160x4000 mm . Weight – 210 kg. Attached is a detailed description of the antenna and assembly instructions.
The antenna is supplied with pre-tuned elements (series “Standard”). You can purchase individual parts and components antennas: frogs, aluminum tubes, wire elements, fiberglass pipes etc.. (Series “Master”).
Each band in antenna feeds by single coaxial cable impedance of 50 Ohms. Antenna RQ-84 requires a matching transformer on 10 meters band. The package does not include the antenna coaxial cable
For selecting antenna it is most convenient to use the switch antennas. In the “Switches” you can find information about such switches.
To install the RQ-84 requires special durable mast (recommended height minimum of 20 meters) and a powerful rotary device.
Features stretch masts with antennas R-QUAD can be found here.
