Long inverted V not working well, why?
how far apart are the ends?
On May 12, 5:02 am, "Rick (W-A-one-R-K-T)" wrote: I just put up an inverted V that is up about 70 feet in the center and about 15 feet at the ends. Each leg is about 130 feet long, or about 260 feet overall, which is right around a half wave for 160 meters. It is fed with ladder line and an LDG auto-tuner. I also have a dipole antenna that's up about 17 feet and is a half wave for certain MARS / CAP frequencies above the 75 meter band, hence it's a bit short for 75 meters. That antenna is coax fed and goes through a different LDG auto-tuner which allows me to use it on 75/80 meters with a good match. The long and high inverted V doesn't work any better than the short and low dipole, and in some cases doesn't work as well. I have checked all the connections on the inverted V and even did a continuity check from each side of the ladder line, up through the feed point, out each leg to the end of each leg, and all seems OK. I have tried switching auto-tuners (taking the one that's on the coax-fed dipole and putting it on the inverted V) with no discernible difference. Seems very strange. Any ideas that might account for why the V doesn't work better? |

Then it should work fine
yes you do seem to have a problem. maybe if you shrtened it up some. On May 12, 10:46 am, "Rick (W-A-one-R-K-T)" wrote: On Sat, 12 May 2007 09:27:47 -0700, herbert.don wrote: how far apart are the ends? Around 235 feet. |

Is there a reason you are using a 160 m antenna on 40/80 meters? A shorter antenna would get the ends a lot higher, assuming you used the same end supports. Tam/WB2TT |
