Re: FSL Antenna

Gary DeBock


After some research I found the FSL design that you used to build your antenna-- it is the 3.5 inch Long Rod model used in the 2012 FSL Antenna Optimization article-- both of which are attached with this email. You probably used the 660/46 Litz wire for this model, as in the design photo.

The number of 200mm x 10mm Russian surplus ferrite rods depends on the diameter of your inner core material, which is probably a little larger than mine. So, 24 ferrite rods is no problem in your design, as long as you have 530-1700 kHz coverage from your Litz wire coil. Best wishes for great DX!
