Hi Art, Make it as small as possible, with as large as possible conductors. Look at any of the small, tunable, loop antennas on the market. As a bonus, you also get to participate in the eternal debate about the voltage found at the ends of a dipole when your own construction begins arcing big time. 73's Richard Clark, KB7QHC Richard, In my case I need the field around the inductance for coupling purposes. To make it smaller a core material would have to be used. I spoke of flattening the tubing but I am not sure if it would be worth it to plate or should it be wound ribbon wise as some of the old Collins inductors or edge wise wound per some of the commercial inductances. Going to the large copper winding really showed up as an improvement in the antenna such that it has wet my appetite ! Regards Art |
