CG-3000 Automatic antenna tuner

The CG-3000 is a very affordable automatic tuner for shortwave 1.6 to 30MHz, for feeding verticals, longwires, dipoles etc. Like the well known SG-230 this tuner is primarily intended to feed wire antennas or monopoles, the antenna connector is simply a high voltage connector. If you intend to connect coax just connect the shield to ground. The tuner has a tuning range of 12 to 1000 Ω, max. power load is 150W.

Once a setting has been found it is stored in non-volatile memory, so that a new tuning on similiar frequencies happens very fast. The tuner uses a Pi network design which has the advantage (compared to L networks) that is acts as an additional low-pass filter, reducing spurious emissions.

The CG-3000 tuner is operated with 12V DC, other cotrol wires are not required. The solid plastic case is suitable for outdoor use, size approx. 365x240x75mm. U bolts with 55mm width are included. The minimal required antenna length is 2.5m for frequencies of 6MHz and up, or at least 8m for 1.8MHz and up. With a small glassfibre pole (not included) and some wires (not included) a good allband antenna is constructed within minutes.

Remote control for CG-3000

The remote control unit for the CG-3000 automatic tuner offers the features to switch the power supply for the tuner, start a rest and show the current status ('tuned'). Comes with control cable and 2m DC cable. Weight 750g.

CG-5000 Automatic Antenna tuner 800W PEP

CG-5000

The CG-5000 is the new high power version of the CG-3000, offering full 800W PEP max., 400W in CW and 250W in RTTY/FM. The tuner uses a new microcontroller with larger memory for stored settings. Frequency and SWR are directly found from the transmitted HF signal, the tuner works with any radio and does not require a special control line. Tuning time is max. 6 seconds for unknown frequencies. If the same frequency is used later again the information is taken from one of the 800 memory locations and tuning is done within a split second. As the CG-3000 the CG-5000 uses a pi network whic hacts also as a low pass filter. A total of 250.000 combinations are possible. The included mounting material is stainless steel, the size is 365 x 240 x 75 mm. A minimum power of 10W is required for automatic tuning.

MFJ-4116 Bias Tee

Used to supply power to antenna tuners or amplifiers or for remote control of solenoids over the coax cable. Usually a pair of these Bias-Ts is used, one in the shack to source the DC power, one at the remote end (DC sink).
Frequency range 1-60MHz, max. 1500W or 50V/1A. Includes DC connector 5.5mm.

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!

TuneRite Tuning Aid

Many recent transceivers offer a "Tune" or"AT" button - which does only work when an external antenna tuner is installed. Now if you want to tune a manual tuner or antenna you have to switch to CW or FM, reduce power, push PTT, tune, then revert back to the mode and power level where you came from. Not very convenient and very time consuming.

Here the TuneRite steps in and offers great help. The following radios are supported:

• All Icom with 4 pin tuner socket (IC-703, 706, 718, 736, 746, 7400, 756, 756ProI/II/III, 765, 775, 7000 etc.)
• All Kenwood with 6 pin tuner socket ( TS-50, 450, 850, 950, 570, 2000, 480 etc.)
• Yaesu FT-100, FT-450, FT-950, FT-857(D) and FT-897(D). FT-450 and FT-950 require a solder bridge inside Tunerite.

TuneRite is very easy to install: With an Icom or Kenwood, just plug it into the tuner socket on the rear, a power supply is not required. With the Yaesu rigs TuneRite is connected to the CAT socket, a cable is supplied. Further the Tunerite for Yaesu offers a connection for Icom compatible tuners.

With the TuneRite installed you just push "Tune" or "AT" on your rig, the radio now sends a continous carrier at reduced power level. At the end of tuning the previously selected mode and power level is back. This eases the tuning process very much, be it with a manual or automatic tuner, or a screwdriver antenna like the Tarheel antennas.

Note: When using the TUNERITE-KW on a TS-480HX (HX, not SAT!), the radio 'thinks' it has a kenwood tuner connected. Since these tuner do not handle more than 100W power, the TS-480HX reduces it's output power permanently to 100w! During the tuning process the power is reduced to 10W as usual.
