This field spreads out in a form of a cone (roughly), say cone (area) of influence. If you use multiple ground rods, then a clearance of two times the length of an individual rod is required to keep the other rods out of the cone of influence of the first. It is merely the same story with staggering dipoles and keeping minimum distance. Hope this helps. 73 de Gamal > -----Original Message----- > From: Martin [SMTP:m5cix@cwcom.net] > Sent: Tuesday, January 30, 2001 10:59 AM > To: rsgb_lf_group@blacksheep.org > Subject: LF: RE: Re: Re: Earthing - correction > > Still don't quite understand the point > > Regards > > Martin > Sounds Good Ltd > Direct Line 0118 930 1701 Fax +44 (0) 118 930 1709 > 12 Chiltern Enterprise Centre, Station Road > Theale, Berkshire RG7 4AA > > -----Original Message----- > From: majordom@post.thorcom.com [mailto:majordom@post.thorcom.com]On > Behalf > Of John Rabson > Sent: 29 January 2001 21:28 > To: rsgb_lf_group@blacksheep.org > Subject: LF: Re: Re: Earthing - correction > > I should have said 'spaced by 2 or more metres' > > ----- Original Message ----- > From: John Rabson > To: > Sent: Monday, January 29, 2001 9:59 AM > Subject: LF: Re: Earthing > > > > In cave radio experiments we find that one x metre rod can be replaced > by > x > > one metre rods spaced by 2x or more metres. > > >
