There are some AC lines that run along the attic in that area and I can look into that. There is no antenna turner being used at this time. I have the K3 and the tuner is in by-pass. Thanks for all the great info and it will keep me busy on the weekend.VE9KK https://www.blogger.com/profile/04720839744779758420noreply@blogger.comtag:blogger.com,1999:blog-2968254002071870786.post-30079333980186908922011-03-10T08:28:05.163-05:002011-03-10T08:28:05.163-05:00Good morning Dick, as for the roof there was no sn...Good morning Dick, as for the roof there was no snow up there and none now.

Also check the braid ground on the pl259. If the analyzer is in the attic while checking - rf in the analyzer will cause strange readings. Look for any AC lines near antenna. Are yuu using an antenna tuner in the shack? If so, be sure the tuner in the rig is off - or they will fight each other and give that type of reading.Anonymoushttps://www.blogger.com/profile/06696153645627164126noreply@blogger.comtag:blogger.com,1999:blog-2968254002071870786.post-54026122602374744562011-03-09T11:57:34.455-05:002011-03-09T11:57:34.455-05:00Have you checked your roof for heavy snow and ice?...Have you checked your roof for heavy snow and ice? How about the roof itself. Any suspected damage? I found that when I had an attic dipole years ago, the swr changed with the amount of snow on the roof. 73 Dick N2UGBAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2968254002071870786.post-55356379908919850562011-03-09T06:42:59.516-05:002011-03-09T06:42:59.516-05:00Good morning Paul, yes that it is strange for sure...Good morning Paul, yes that it is strange for sure but ham radio is all about the challenge and solving stuff that just does not seem to be right at the time.

I ran new coax to the 40 meter dipole. So the coax when hooked up to the 40 meter dipole gave me no troubles...but that does not mean something went wrong when I moved it from the 40 meter dipole at one end of the attic to the 30 meter dipole at the other end of the attic. On the weekend I am going to do more investigating.VE9KK https://www.blogger.com/profile/04720839744779758420noreply@blogger.comtag:blogger.com,1999:blog-2968254002071870786.post-79403201113434379702011-03-09T06:28:01.618-05:002011-03-09T06:28:01.618-05:00Hi Mike, I am puzzled.

I hope you, or someone else, knows what is wrong. 73 PaulPaul Stam PAØKhttps://www.blogger.com/profile/13472039726489965017noreply@blogger.comtag:blogger.com,1999:blog-2968254002071870786.post-28732736845013414872011-03-09T06:26:00.541-05:002011-03-09T06:26:00.541-05:00Hmm indeed.

A more likely explanation is a bad cable / connections, though that would affect all bands. But it is surprising how many problems of this sort have turned out to be the cable from the radio to the antenna.<br /><br />Having a dipole in the attic will affect it by lowering the frequency but after you trim bits off to get the best SWR in that position the SWR should not change.Anonymoushttps://www.blogger.com/profile/11984840704237681015noreply@blogger.com
