Easy to use on all band
|
Time owned: 6 to 12 months

I had used a couple of years CG2000 Automatic antenna tuner. It is also called a coupler. Max. power of CG2000 is 150W. I used it "barefoon" with TS-480SAT. Antenna tuner of TS-480 was not in use. I see no idea to use two successive tuners. I found that CG was coming out with a high power model. Its max power was 800W PEP and 250W CW. I placed an order because 600W 4CX800 linear was under construction. I had to wait five months to get the tuner. The factory may have been closed during olympic games. At the moment all models are available from the shelf here in Finland.
The use of high power model does not differe from
earlier models. You must tune using low power. When this is done you can raise power. I tune first without a linear using 15W from the transceiver. You can tune the linear using still low power fom transceiver.
When this is done you can raise the power of the transceiver to 35W which is normal and maximum value. Output is 600W in my case. It depends of plate voltage.
CG5000 does not work on 6m or 160m. The reason may be my long radiator (25m), or maybe not. CG2000 was working fine from 6m to 160m.
Tuner is selective
When the tuner is in tuned condition, the S-meter shows about the same value as it shows when I use inverted-V on 40m and 80m. If the tuner not tuned S-meter shows much less.
Tuner is expensive
You could buy a small beam with same amount of money. However this is an all band antenna. It is an invisible antenna, if needed. A random wire to nearest tree or pole.
It needs a good ground. Follow istructions of the manual.
It may be dangerous.
Nobody, any human being or a pet may not touch the antenna element. 100W is more than enough to cause serious burns. It is RF and perhaps does not kill but burns may be result if not protected crefully.
Noise
The tuner generates computer type noise. It does not cover whole band but blocks the freqency just in use. Who makes a filter to reduce this noise.
Warning
If you change CG2000/CG3000 to CG5000 be careful with +12DC. Connectors are same but the connection is different. Manual has good adwise: RED wire is +12V. A change has to be made.
