You want to transmit or just receive on several HF bands but you lack space ... Choose the OTURA 3 ! It is an HF multiband antenna consisting of a 8.25 m vertical whip coupled to an unun 1:4 ratio, it operates without traps (which limit the bandwidth) and radian. Easily and quickly installed, the OTURA 3 will fill you with its performance and robustness !
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 !
18 MHz 1/4 wave vertical antenna delivered with 3 wire radians. Very robust tubes with large diameters and thicknesses (2 mm), wide bandwidth, very low SWR. Connection to the 50 ohm coaxial cable directly by 2 screws (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
14 MHz 1/4 wave vertical antenna delivered with 3 wire radians. Very robust tubes with large diameters and thicknesses (1,5 and 2 mm), wide bandwidth, very low SWR. Connection to the 50 ohm coaxial cable directly by 2 screws (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
10 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 2 screws (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
7 MHz 1/4 wave vertical antenna delivered with 3 wire radians. Very robust tubes with large diameters and thicknesses, wide bandwidth, very low SWR. Connection to the 50 ohm coaxial cable directly by 2 screws (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
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.
