D-3000N Discone Scanner Antenna, as above, but frequency range from 25 to 3000MHz, N female connector.

Desktop Discone

The Desktop Discone 18065 is one of the best solutions for indoor receiving antennas. The antenna works with the well known Discone principle and covers a frequency range from 25 to 2000 MHz. The heavy magnet base can be placed anywhere, for example on the window ledge or on the heater. The antenna should be placed near a window for best reception results. 4m coaxial cable with BNC connector are included.

Antennas for handheld scanner

In spite of the highly sensitive receivers, a better (in mos tcases longer) antenna can improve reception dramatically, especially on lower frequencies.

Ducker IL/PL/TL

Put the Miracle Ducker on your broadband-handheld portable, and open up a world of HF receive you never thought possible!
Most popular broadband rigs like the VX1-7, THF6A, IC1-10 and others are just plain dead when it comes to receiving AM, HF ham bands or shortwave with the supplied rubber duck antenna. They say, "Use a large outdoor antenna for these bands." So what's handheld about that?
Now the Ducker IL (inline) gives you all the portable performance you've wanted. The Ducker provides as much as a whopping 30dB gain on low-frequency receive, using the original rubber duck. Ham, shortwave, even AM broadcast comes booming in like you've never heard before!

The Ducker IL plugs right into your radio, with the original rubber duck mounted on top. The exclusive Miracle Whip C-VAT autotransformer tuning system lets you dial in the frequency of your choice with convenient, single knob tuning, peaking up receive signals that you never thought you'd hear on your radio.
And you retain full access to VHF/UHF transmit with just a click of the dial. Imagine - your little handheld now receives everything from AM broadcast up to high UHF, and you can still operate 2 meters, 220 and 450 with the same antenna. Finally your rig lives up to its promise!

HF active antenna AA-150

125cm long whip antenna optimized for the long-, medium- and shortwave range, very robust construction (all stainless steel) and excellent electrical data. Can be used indoors or outdoors, very suitable for yachting and motorboats for Navtex reception. Very high IP3 with +30dBm which is usually only found in receivers above 2500 Euro. The receiving gain is frequency compensated over the whole shortwave range and adjusted to the typical noise curve of the athmosphere. DC feed over the coax cable, not additional cable required. The necessary Bias-T is included. Operating voltage 12V.

Shortwave wire antenna

Excellent wire antenna for shortwave listeners, consists of 20 or 40m PVC coated copper wire, two insulators, all required hardware plus a magnetic MTFT balun in weatherproof case. The balun is explained here in more detail. With this balun the antenna can be fed with any length of coax cable. With an additional tuner this antenna can be used for transmission in the range from 3.5 to 30MHz.

Antenna Splitter ASA-15

ASA-15

ASA-15: Antennea plitter for shortwave up to 70 MHz.

The antenna splitter ASA-15 distributes the signal of one receiving antenna to up to five receivers. Each of the five outputs has an individually selectable wideband amplifier with 12 dB gain. Further a 15dB attenuator is integrated in the input to reduce strong signals. The internal distribution is done with low noise amplifiers, preventing mutual influence of the outputs on each other. The selected configuration is shown with LEDs on the front panel. A power supply (12V/1A) is included.

This splitter is not suitable for transmitting.

ASA-42: 4x2 antenna distributor for shortwave up to 70 MHz

With the ASA-42 antenna distributor the signal of four receiving antennas can be distributed to up to two receivers. The mutual influence of the receivers is reduced with wideband amplifiers, allowing to use multiple receivers on the same antenna. The selected configuration is displayed with LEDs on the front panel. A power supply (12V/1A) is included.

This distributor is not suitable for transmitting.

Wideband Antenna Spliter/Combiner Diamond SS-500

Serves to connect two antennas to one receiver or vice versa - one antenna to two receivers. This device contains a wideband transformation network which combines both inputs and transforms the impedance. Further this networks isolates both inputs against each other.
The insertion loss up to 200MHz is less or equal than 0.8dB, isolation between both inputs is 30dB (@3-200MHz).
Due to the high isolation between the two inputs the SS-500 can combine any two antennas, also with different frequency ranges, without one antenna shortening the other antenna.
50 Ω impedance, SWR better than 2:1, Size 80x60x30mm, Connector 3x PL female. This splitter/combiner is not suitable for transmission.

SAT antenna TA-1 Turnstile

Crossed dipoles with one director element for reception of LEO sats in the frequency range 137 to 152 MHz. Gain at high elevations 0 dB, at lower angles up to 4 dB. 50 Ω feed, SWR <2:1, total height 1300mm, diameter 1065mm, weight 2kg, Windload 90N @ 160km/h. Includes mast clamp.

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 65mm is included. Height c. 100cm, weight c. 1100g, connector PL female.
