QRZ Forums. I'm thinking to buy this tuner and would like to hear, if this tuner is tuning automaticaly indeed all bands from m up to 10 m with an inverted V antenna of 2 x 10 mtrs. Any experiences with this tuner??? I've been using this tuner in a maritime mobile situation for 7 years - loading the backstay. Works extremely well.
Only output on the SGC is for a wire. So, must be used as an integral part of the antenna, such as with a long wire, or a mobile whip W2HDIJan 6, Of course, the shorter the antenna, the poorer the performance will be.
I didn't try it on 60m. I am currently using my SGC on a stealth antenna. The coupler is mounted close to the counterpoise, to ensure a low-impedance connection on the HF bands. With this setup, the SGC has no trouble finding an acceptable match in the General Class portions of80, 75, 40, 20 and 10m.
I'm not saying that it always found a perfect solution - only that it found a solution that was acceptable or better, in my case. With W on SSB, I have made a fair number of contacts with this setup on75, and 40m, plus a few on 20m. Local performance on 10m is dismal, at best. As W2HDI noted, there's no coax connection on the antenna side - and for good reason. These couplers are designed to match a very wide range of impedances.
With very high-impedance loads, the voltage at the antenna terminals and along the feedline can get quite high.
High enough to destroy typical RG-8 or smaller coax. Not to mention the losses associated with trying to match a or load from the transmitter end of a coax cable.QRZ Forums.
I have had and played with a number of auto tuners in the past. Are they really that much better? Last edited: Jul 24, W7KKKJul 24, I think the LDG products are just fine. However, they are all made to tune from the shack, the SGC units are remote, which is nice as if you have a long run of coax putting the tuner at the antenna feed point will knock down all the loss on the coax side by keeping high SWR off of it. I picked up a small LDG ZPro recently to remote mount in a weather proof box, it is powered from AA batts and should run a year or so off a set.
K4AXJul 24, The only thing that makes the SGC tuners better is that they are mounted at the antenna feed point.
The SGC Line of tuners are good but I don't think they are worth the extra money you have to pay for them, the best one I have found is the SGC I have actually tuned up a aluminum lawn chair using my radial system in my back yard. I hope this helps. K7DMBJul 24, I cannot answer your question directly.
I can tell you that SGC equipment is designed and manufactured for the commercial maritime market. My SG autocoupler's past is unknwn to me, but I've had it close to 20 years witth good results. OK, well 20 years of use says something for longevity anyway. KY5UJul 24, I know well what you are saying about salt water damage. I worked for the Navy as a civilian electronics mechanic and did lots of overhauls of the equipment.
And you would be amazed how much damage it can do when it sprays the insides of a submarine that does not come in for some time for repairs. And yes, I saw more than one that this happened on.
Auto Tuners~Is SGC that much better?
I grew up on the west coast smelling salt water. Now I miss it but I do have some nice lakes close by. They just don't have that same smell. W7KKKJul 25, SGC products are very good. The enclosures are very ruggedized and many can be used outdoors without any additional protection. The ones I've had also had a lot of self-diagnostic tools standard; you just look at a row of LEDs to determine what, if anything, is wrong.
You see a lot of SGC stuff on marine vessels, which probably points to robustness and reliability. LDG stuff is mostly "hobbyist" stuff for ham radio. It won't ever see rain or bad weather, since the rig itself won't tolerate that. But it works fine and thus far in two years of almost daily use hasn't failed yet! Compared to the rest these two are the best. I will agree with that. Just never an SGC.When you subscribe, you receive only messages for the product you have subscribed to.

I have also ran 2 17' radials around my patio. Not only does this tuner manage to tune this setup but the SWR is less than 1. Have not had much free time to play with this setup. Tuning is fast and easy. Just transmit and it tunes, storing in memory for even faster tuning when you return to a previous tune. This tuner is not cheap but after experiencing the SG, I would buy it again. I have no regrets! I have owned 2 SGC antenna tuners over the years.
I bought my first SGC in I have never had any problems with my SGC My SGC tuner has always worked great, and never had a problem tuning up my antenna. I strongly recommend this tuner. It is highly reliable. You will have a hard time finding a tuner built with more quality. This tuner works very good,as a extra i added a "Smartlock".
I tried several other tuners but this is the one. Now i operate on a CB antenna of almost 2 mtrs but a 2,72 cm whip is also tried. As a costumer you need support when you need but i you got no answer on a simple qeustion. I bought a second one because almost no EU shop has a new one in stock.Local Knowledge.

If you don't have the manual for it, you can download it from www. You have to feed it When you read the manual you will see all sorts of suggestions as to how to use this item.
I use mine to tune a 33' vertical wire with counterpoise wires. About the only thing you cannot feed with the SG is a coax-fed antenna. Provided the wire is long enough, you are good to go. Efficiency may vary with your radiator design.
NA0AAJan 30, The manual tells you all about this. As fas as I can see, you connect one end of the antenna wire to the terminal on the tuner.
You should also have an earth connection to the tuner. If the tuner is in a home installation, they recommend using an inverted bucket to keep rain off the tuner. It should be fed with coax from the transceiver. You can also use it to tune dipoles and loop antennas. Check the SGC website. You can download their stealth manual that give a lot of good information on types of antennas. Don't forget that if you feed a vertical antenna you have to have a suitable ground radial system or it won't work very well.
How have other done it that make it easy? Oh and it is a 2 story house with no balcony. SO I looked at is as interesting. Well, I have no idea if this will work but: First: Cut counterpoise wires for all bands of interest. Ground the coupler. Second: Take a long piece of thin wire [stealth] and run it out a window to the most distant possible point - the longer the wire and the higher up the better.
If you could go from the ground, up to the top of the second floor with the wire then to a distant tree, an inverted 'L' configuration you should get a reasonable antenna. You can tune with that SG almost anything - 25' of wire with counterpoise - how about a vertical running up the outside of the building? A loop under the eaves? N4CRJan 30, Why for a countpoise I was going to use the copper water pipe. This is where it gets interesting.
If I run the unit from the ground I have to go 40 feet up to the antenna. If I mount the unit by the bedroom window I have 35 feet back down to the counterpoise. I have heard of trees. It is probably going to end up as a foot wire at about 45 degree angle to back fence.When you subscribe, you receive only messages for the product you have subscribed to.

I used it with the QMS system bolted to the top of the 4 vehicles and worked hundreds of cw mobile contacts. It was best when on 40M or up I now use it to tune the radials on my Hustler 6BTV on a push-up pole at about 25 feet. It has never failed to do whatever I asked I have never tried the pre-amp I'd have NO hesitation at all in buying it again.
I moved qth and needed small discreet antennas. Unfortunately it took three attempts to get one that worked however this is what I think of the result. The pre-amp is almost useless on my 50ft approx. Location meant that the wiring up was a bit of a nightmare however, now that its sorted it is brilliant. All bands top to ten tuned in seconds.
I find myself changing bands just because i can. This tuner is basically thewith the optional SmartLock Pro control head as standard equipment, a receive preamp, and a PC interface to allow you to control the tuner elements from your PC screen. According to SGC, this tuner was originally designed for a non-amateur application that needed the PC control feature. That feature is of no value for amateur use.
The preamp may be useful with very short antennas whips, very small loops, etc. With a long antenna mine is feetthe preamp is in a perpetual state of overload and you can hear nothing on any band other than the preamp generated garbage.SGC 2020 cw digital filter and dsp
Unfortunately, the circuitry added to support these features contains two oscillators that generate spurious signals that you can hear in your receiver. There is no fix for this problem.
If you do any DX work, you'll find it impossible to live with the spurious signals, which sometimes are as strong as the weak station you're trying to hear. And- the seems to be able to match difficult loads more easily such as my end fed half wave on This is a tuner to avoid.
