HF broadband antenna consisting of a 10.6 m vertical aluminium whip coupled to an unun 1:4 ratio. The OTURA 3-10 operates without traps (which limit the bandwidth) or radian. Can be used in 1/4 wave on 7 MHz (radians to add) ! Easily and quickly installed, the OTURA 3-10 will fill you with its performance and robustness !
Wide bandwidth, low SWR without tuner, higher gain than a dipole, and quieter reception. Reduced fading for stable signals. Rugged build (Ø60 mm aluminum box, strong coax, 2.5 mm² copper), Teflon PL connector, no balun needed, easy tuning.
Double dipole 1/2 wave 18 and 24 MHz for amateurs of the WARC bands, lengths : 9 + 6 m (4 wires). Robust aluminum balun with SO-239 (PL) connector and insulators at the ends.
8.25 m "versatile" whisk delivered with HF BOX and 1 wired radian. Can be used in high or low impedance from 3.5 to 70 MHz. Aluminum tubes, diameter 40 to 16 mm and weight 6.5 kg. Can be used with coaxial cable, single wire or "twin-lead" depending on the tastes ... Provide a suitable manual or automatic coupler.
Delta-loop antenna, the "queen of DX", monoband 50 MHz/3 elements combining performance and robustness of construction. "All grounded" design greatly reducing atmospheric QRM in reception (static). Compact and easy to adjust with its gamma-match.
Impedance transformer (1:4 ratio) to transform a short wire (6 m minimum) or an aluminium vertical tubing into a multiband antenna. Use with automatic or manual coupler recommended. It is the ideal solution to transmit during the week-end or the holidays.
14 MHz/2 element monoband Yagi antenna, space-saving, combining performance and robustness of construction. "All grounded" design greatly reducing atmospheric QRM in reception (static). Easy adjustment by gamma-match.
Dipole 1/2 wave 7 MHz shortened, length: 13 m. Robust aluminum balun with SO-239 connector and insulators at the ends + CHOKE BALUN integrated.
21 MHz 1/4 wave vertical antenna delivered with 3 wire radians. Very robust tubes with large diameters and thicknesses (2 and 1,5 mm), wide bandwidth, very low SWR. Connection to the 50 ohm coaxial cable directly by SO-239 (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
