| Horizontal Delta Loop Feed Point | W4WCS | on 7/8/22 |
| I have put up a Horizontal Delta Loop long enough for full wave at 80 meters. It has been up for almost a year. I did not tune it to the perfect length. I use it primarily at 20 meters and it works fine. I fed it at the center of one of the sides with ladder line to a balanced tuner. SWR is good. One thing I could never find is the best feed point. Is better to feed at a corner? Or the center as I did? And finally does this have any big impact on directivity. Thanks 73 Bill W4WCS |

| Thanks Zack I did not know there was that much antenna info on the website. Shame on me for bad Searching! Great advice! Very helpful! Bill |

| Thanks for that info Zack. I am trying to digest it. I was thinking about a multi band center fed wire dipole. What would you recomend in that case with coax feed? Thanks Bill |

| I got my General a while back. Finally getting into HF! Bought a FT-857D and researching antennas and tuners. My sitiation is such that I need to use my attic for my antenna farm:) I am considering several wire dipoles and possibly a loop tied to an automatic tuner. MFJ-993B or a remote tuner. Oh and COAX for the moment. I can figure everything out except BALUNS.........!!!!!!!! I see the purpose, prevent rf from feeding back down the shield, balance between the coax and dipole. BUT........why a 1:1 or 4:1 or current????? I have no idea what I need and why???? There has to be a good tutorial somewhere? I just cant find it.. HELPPPP and thanks in advance. Bill |
