DIAMOND D-130J / D-190 / D-3000 Discone

Discone

The Discone antenna is the most suitable form for a wide band omni-directional antenna. It is used by military as well as other commercial services worldwide. The Diamond Discone antenna use stainless steel for most parts, the construction is very solid. This ensures a reliable operation for many years. The Diamond discone antennas are suitable for transmission with the VHF/UHF amateur bands and can replace or complement the usual staion antennas.

The D-130J works for reception from 25 – 1300 MHz, transmit.wise it's useable on 6m, 2m, 70cm and 23cm, with limitations also on 900MHz /GSM). This antenna is available with PL or N socket.

The model D-190 is designed for a higher frequency range, from 100 to 1500 MHz. This makes the antenna somewha tsmaller and less visible. Transmission is possible on 2m, 70cm and 23cm, partially with rteduced power up to 30 W only. See data sheet. This antenna comes with a PL female socket and 10m RG-58 cable with PL connectors on each end.

The Diamond D-3000 Discone is used for reception from 25 – 3000 MHz, transmit on 6m, 2m, 70cm and 23cm. Connector is N female.

Note:
In the paperwork accompanying the D-130J (18061) the max. diameter is mentioned as 41cm. This is an error, this should read "max. radius". So the max. diamteer of the antenna is approx. 82cm.

Boni-Whip Active antenna

Boni-Whip Antenna
Boni-Whip Bias-Tee

Despite its small size (only about 14 cm short), this antenna has excellent receiving results at long-, medium- and short-wave range as well as for VHF up to 300 MHz. Already at low frequencies the Boni-Whip provids very good receiving results. Already applicable from 10 kHz, it is a good choice for the low-frequency interested.

The antenna is an ideal addition to all short-wave receivers and SDRs. It is supplied via connection cable, the required Bias-Tee is included. All antenna connections are BNC standard.

Antenna electronics is in a weather-proof housing. Because of the changeable beams, the antenna can be used with other or your own beams or wires.

Accessories for Boni-Whip

The Boni-Whip antenna is supplied without cable. This is understandable because everyone needs a different length. We offer several cables for this antenna. You need two cables: at first one longer cable between antenna and the DC injector (both sides BNC), and secondly a cable between the DC injector (BNC) and your radio.

Further you need a 12V (13.8V) DC power supply which can supply at least 300mA current. The connector is a DC coaxial connector on the DC injector, our article 42913. Power Supplies are to be found here. Optionally a mast mount bracket is offered, depending on the installation positon of the antenna (ref. 18067.MH). A surge protector (ref. 21049.BMF) can be useful for the Boni whip to protect the receiver. It should be used if a good grounding is available near the installation position. To protect the BNC connectors against rain we offer self vulcanizing tape, ref. 23065.

Bonito Loop ML-200

Mega Loop ML-200 ML-200 RX Antenna

The Bonito ML-200 is a wide band active antenna for reception of long, medium and short waves as well as the lower VHF band. The antenna is is characterized by a small apcking size, low noise and excellent signal levels.

The ML-200 consists of a flexible, braided wire loop with large wire gauge. The loop is connected to the amplifier, both are installed by hanging the wire to the wall, into a window, in a tree or on another suitable supports. The amplifier is supplied over the coaxial cable (not included) from a supplied Bias-T. This Bias-T has connectors for an external supply voltage as well as a socket for a USB cable. The voltage can range from 5 to 15 V. The USB connector makes the antenna very well suitable for portable operations with a computer.

Despite the high amplification, the ML-200 has a very low noise level, as comparisions to other active antennas have shown. The antenna can be used from long wave (9 Khz) up to the lower VHF range of 200 MHz. The amplifier has a very high 3, order intercept point of +40dBm. This results in a very high distortion free blocking dynamic range. The amplifier is protected by a twofold overvoltage protection. With this protection the antenna not only survives a thunderstorm but can also be used in vicinity to transmitting antennas, for example in the garden of a radio amateur or on a sailing yacht.

With the small packing size and the USB power supply the ML-200 is very well suited to accompany you in a vacation. For example the antenna can be easily installed with two suction cup holders in a window. The coaxial cables are not supplied because most customers require different lengths. WiMo does provide several ready made cables, and can also manufacture a cable tailored to your requirements.

Packing size 20 x 20 x 5cm, weight 480 g. Connector on amplifier: BNC, HF-Connectors on Bias-T: 2x BNC. Requires additional DC cable or USB cable for power suply. Supply voltage from 5 to 15V DC, max. 40mA.

KE-137 QFH Circular Antenna for NOAA and ACARS

Diamond KE-137

Circular polarised antenna for reception of NOAA weather satellites on 137 MHz, or ACARS transmissions on 135 MHz. The KE-137 is a quadrifilar helicoidal (QFH) antenna. Due to the construction of the antenna the satellites are picked up at a very low angle above the horizon, but equally well when right over the antenna. The circular polarisation is required to compensate fluctations of the signal strength. And the same applies to aircraft and their ACARS transmissions on 135 MHz, which can be received with the same antenna. The antenna is weatherproof and intended for installation on a mast. A mast clamp for mast diameters from 25 to 65 mm is included. Height c. 100cm, weight c. 1100g, connector PL female.
