1. Re: LF: Re: Resonate the antenna, or not? (score: 1): Author: "mal hamilton" <[email protected]>; Date: Tue, 22 Mar 2011 19:20:56 +0100; Tnx info Markus I mean use a ferrite core inductor to reduce wire resistance to resonate the vertical. I have already put 162 turns on a 0.5cm diam barell 1mm pvc insulated wire and only get 14.5 mH; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-03/msg00351.html (24,242 bytes)

(score: 1): Author: Markus Vester <[email protected]>; Date: Tue, 22 Mar 2011 12:52:02 -0400; Hi Mal, no, I would not recommend transmitting on a vertical without a resonant loading coil, it's not really efficient. A 150 mH coil would not be very difficult to make. For a straight single layer; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-03/msg00516.html (22,356 bytes)

(score: 1): Author: "mal hamilton" <[email protected]>; Date: Tue, 22 Mar 2011 16:01:24 +0100; Markus Have u discovered another method of resonating a vertical type antenna other than a large air wound water butt. I was thinking of a smaller coil with ferrite core. In my case I need about 150; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-03/msg00749.html (20,745 bytes)
