How can I do better than that, for a ground? There's no harm in grounding the shield. I had a transformer with both grounds connected to the shield. It worked. When I changed it so that the primary (antenna side) connected the antenna to ground and the secondary (receiver side) connected the shield to the center conductor, Signal levels increased dramatically. In your case, your tv transformer was designed to work with tv freqs (above HF). It may work just fine for you - it may be a big bag of suck. Try it and see is the best advice. We could swap transformers and both get better/worse/nochange results than what we had before. Just because something works for someone else in here, that does not automatically mean it will work for you. There are too many variables. A general rule of thumb is that your antenna won't do you any good until you put the thing up, so quit talking about it and string it. Then come back here and tell us what your results are. It may be just right (with no further fiddling required) for what you want to do. However, if your radio is deaf, or overloaded after you put your antenna up, there is probably someone in here that can help you. Step One: Hang the antenna. You can mod it later if you need/want to. -=jd=- -- My Current Disposable Email: (Remove YOUR HAT to reply directly) Believe it or not, that is pretty much what I have decided to do, as soon as time permits. I thought I would be stringing it yesterday, then today. Tomorrow is pretty much out, and then I am going to be out of town for a few days. Will have to get it some time next week (probably Thursday.) In the meantime I am trying to find the most likely design to try first. I know nothing ever works as well as you want the first time out, but am still trying to find out as much as I can about this business. Thanks, Dave |
