I made a balun for this antenna according to the manufactures
instructions and I still have high swr. HELP. I do get good signal reports though. The ladder line is only verticle for almost 12ft and then drapes off the roof. Best way it could be installed right now. Using a kenwood ts440s with auto tuner. No luck on ten meter yet!!! |

No luck on ten meter yet!!! I have found that only a couple of bands can be tuned with the built-in tuner. For the rest you will need an external tuner that can handle SWR's greater than 3:1. With the current sunspot cycle, you would be lucky to make a ten-meter contact (other than locals) with a 6-element beam, let alone a G5RV. Dick - W6CCD I don't think much of the G5RV, but that is a personal opinion without ever having one up. I do use an OCF antenna with all its problems. Mainly for 80 and 40 meters. Ten meters has been opening up some and I have made a few contacts on it. I am not much of a 10 meter operator. I do have a triband beam up and it is much beter than the OCF for the bands it is cut for , but I have heard many 10 meter stations and beacons over the last month. I have even made a few 6 meter contacts out of the local area. |

Thanks for the input though!!! |

A few questions here. Where is the balun located, and what type is it? Internal tuners tend to correct up to only 3:1 or so. There is a good chance that you will still need an outboard tuner. Something like a MFJ 949 would probably do the. If you do use that, you can probably take the balun of the radio end, (if that is where it is at) and run the ladder line directly to the tuner. - 73 de Mike N3LI - The balun is at the feedpoint. It is constructed as per mauf specs. 4" pvc with ten turns of the coax around it, secured with zip ties. |
