Dear all, I want to purchase a strong CODAN base antenna; I need your kind suggestion in this issue whether which type and model is good for a mountain area. ...
I am new to the group. I was lucky enough to buy one of the last SGC- 231s at Radioworld in Canada. I live in the sixth floor of an apartment building. I have...
0.02$ How about feed the stealth wire and the extended buddipole 'vertical' both using the balanced output. Both ought radiate then - you would effectively be...
Hey everyone. Are anybody connected SG230 and marine HF trcvr Icom-m710 or where i can find wiring diagram and position switches in M710 for this wiring?...
Hi... Are you just wanting to feed the coupler with 12 volts from the Icom? Dave-N9ZRT Hey everyone. Are anybody connected SG230 and marine HF trcvr Icom-m710...
VA3CHD, Dave here. N9ZRT. You ask some great questions. I have copied them below and will reply. I encourage others to add to my comments, or correct me if...
... This sure corresponds to my experience. A long whip on a even a modest metal balcony is pretty easy to tune. The question is, why so? I'm *guessing* it's...
Here's a thought for the pot. The counterpoise for a smartuner has to be electrically longer than the radiator? In that case cut the wire so that it's no...
Hi Guys Counterpoises are an important aspect of ANY antenna operation and the thumb rules around them are not unique to Smartuners. Pierre used to say the...
Terry, Thanks so much for this post below! This will be a "go-thread" for the archives! Dave-N9ZRT ... WX7S wrote... Hi Guys Counterpoises are an important...
Hi Terry, Many thanks for the clear explanation. I'm looking forward to your plots. 73 de John PA 0 WIT Hi Guys Counterpoises are an important aspect of ANY...
Hi Scott, I do not recommend it. I tried and connected a switch myself, but zapped the coupler. So I had to send it to SGC for repairs. Fortunately, they have...
Scott ... There is no need for a Smartlock ... Anything that interrupts power from the battery has the same effect because the relays are locking, they stay in...
Very interesting Dave. I thought that the the counterpoise had to be near a quarter wave for a single element and had to be larger than a quarter wave for an...
I use my SGC-239 to tune a 160 meter centerfed vee, which is 256 feet in length. I use a random length of about 100 feet of 450 ohm ladder line for the...
We share some of the same problems, tuning 160 through 10 meters is often good except for one band. My problem was 80 meter CW.I like this idea, never thought...
Hi Bill, Yup, oddly, there were some parts of some bands where I could get a flat match, and then 50 kc away the tuner seemed to get confused. The balun seems...
Thanks Rob, my antenna configuration is different, its like a 60 foot vertical radiator falling over at 45 degrees. The base is 8 feet high with 100, 50, 31...
Well, my SGC-239 quit working several months ago, and I was going to pack it up and donate to someone in this group. But I thought I would give it another...
Well, I'm back on the air using my SGC-239. Essentially, it is my half G5RV with the 239 stuck on the end of the balanced line. When I first set it up it...
Gentlemen, I have a half size G5RV in the garden and just ordered a SGC coupler I have a question in positioning the coupler, what is the best place to locate...
Hi Garry, To be honest, i would start with what is most convenient for you to install. It may work perfectly. But if not, then all the solutions you mentioned...
Why would my SG-237 tune 10-80 but not tune 40m band? I am using a 102 inch CB whip mounted on left rear quarter panel of my truck. Antenna is mounted atop a...
Hi Jack, For one reason or another the little coupler does not like the length of the 102" whip. I would add 2 feet of insulated copper braid, winding raw wire...
... Mine tunes the 102 whip OK on 40 M. It will also tune a 4 foot loaded CB whip on forty . Not as efficient, but I have checked into the Beehive net from...
