Re: [TowerTalk] SteppIR gain - Two Feed Lines (score: 1): Author: Lee Buller <k0wa@swbell.net>; Date: Wed, 16 Mar 2005 16:44:39 -0800 (PST); Two feedlines to the SteppIR is not a bad idea, but would take some engineering. Have one fiberglass tubes for 40 through 10 on the driven element and two reels for belerium copper strips in two diff; /archives//html/Towertalk/2005-03/msg00430.html (7,301 bytes)

Often it is just one component. 73 Tom ___________; /archives//html/Towertalk/2005-03/msg00440.html (8,311 bytes)

Matching does not have to be perfect. Only reasonable. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers",; /archives//html/Towertalk/2005-03/msg00452.html (7,827 bytes)
