In this video I review the antenna tuner CG-3000 from CG Antennas.
I also open it and show you the inside, and I do a simple and effective installation.
Hope you like it and find it useful!

Thank you for this interested video an the improvment with coils and relays. I also use this antenna tuner. Possibly you can report about the improvement after you have done theese. TNX and 73 de Manfred, DC2FK, North Germany

I’ve mostly seen these tuners on sailing boats. Where they sit right under the deck and are connected directly to an isolated aft stay. (The cable that pulls the mast backwards) That cable length is “random” and depending on the mast length. That is different from boat to boat.

Tnx for video, i have it use 20 meter wire but i cant tune 21 mhz. ? very high swr about 2.5 swr, also 28 mhz not good swr i thing my Wire lenght is incorrect. I use horizantal wire,and do youtest it 200 waats or more ? :) 73' de TA4AU

Mehmet thanks for your comment! Actually you are using a resonant length with very high impedance on the end! You can damage your tuner because very high impedance means very high voltage inside the tuner and capacitors and relays can start arcing! Decrease the length to 16,5m or increase to 30m and you will be fine. I never tested the tuner with more than 100w. My amplifiers deliver up to 2,5KW so with only 5w in I get 400w++ output and will be too much for this tuner. If you look hot higher power tuner have a look on eBay for n7ddc 1KW antenna tuner. Hope this helps! 73!

Hi, you said you use 10m of wire with this tuner. The very thing with this kind of tuner is to use a length of wire that is NOT a half wave (or a multiple of that) for the band to use it on. Or, in other words, the length of the connected wire should not be resonant for the band that you want to use. Your use of 10 meters of wire is a half wave for the 20m band. Do, there it will be resonant. That is not preferred. And it is also resonant for 10m ( a whole wavelength)

Yes 10m of wire will be resonant on 40, 20, 15 and 10m. I know that half wavelengths must be avoided because they make the tuner develop high voltages inside. In this tuner, operating up to 100W is safe for the tuner. Less than 10m of wire will have poorer performance to work on multiband.

@@ct7ahv Hi Pedro, ok, I just thought I should mention it that it's better to avoid the resonant lengths of wire. I have a CG-3000 myself, which I occasionally use. The tuner is situated at ground lever and an almost vertical situated wire of 9 meters is the antenna wire. I use a ground-rod as counterpoise. It does work, though it seems to be a bit of a noisy antenna (most verticals are, apparently) not being symmetric. Anyway, trying out different antennas and experimenting with them, is always interesting, I think. I myself am quite intrigued by "magnetic-loop antennas" I'd say, enjoy the hobby, but I'm sure you do, looking at your QRZ-com page. 73 de PC7H, Roy.
