Especially K3!<br />Not having RFI up to now, means that you have an excellent RFground system.<br />Using a counterpoise to avoid the RFI caused by the MagLoop you are curing the effect but not the cause.<br />Check the MagLoop for similar effects on other frequencies or try to disassembly it and look for any obvious or not, faults!<br />It is very convenient to have an indoor antenna but it is more inconvenient to have problems with it!!!<br />73<br />sv3auw/m0lpt Petertakis perreashttps://www.blogger.com/profile/15699638852276558674noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-16602669592927223772010-02-09T18:44:06.145+00:002010-02-09T18:44:06.145+00:00Hello Julian, I've been searching for RF groun...Hello Julian, I've been searching for RF ground solutions in de past when setting up my previous station. There are some simple rules. 1st a good RF ground is almost impossible if you're at the second floor. 2nd keep ground connections as short as possible (impossible if you're a the second floor). 3rd ground at a central point, best point is right after the antennatuner. If grounding to a proper groundrod with short leads isn't possible you can try 2 solutions. The easy one is building a counterpoise of 1/4 wave wire for every band one. Disadvantage is the length for 80m and 160m. The other solution is tune your ground to maximize the amount of RF flowing to the ground. I got a MFJ artificial ground for that. It helps, but since I haven't got a IMD meter I cannot see the effect on that. 73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.com
