| HYGain AV680 Vertical | kylegmd | on 24/7/20 |
| I have a HyGain AV680 Vertical antenna fed with LMR400 (50') connected to an Icom 7610. I'm getting high swr readings on all bands which indicates I have a short someplace. I have a MFJ 269b meter and have disconnected the feed cable at the antenna and checked for shorts on the feed cable. Feed cable is good. I put this antenna together myself and in the process discovered that the matching box had several un-soldered connections which I fixed. What would be the best approach to checking the antenna for shorts and determining where the short might be. MFJ tech support was no help. Any suggestions would be greatly appreciated. I also have a Buck master 7 band dipole that works great fed with LMR400 as well to the 7610, so I know it is not the radio or the feed line.giving me problems. I dont see any obvious construction problems. |
