Slow wave antenna design for top band
"Cecil Moore"
Approximately a foot and a half of 75m Texas Bugcatcher stock will be self-resonant at 4 MHz. That's 90 degrees of antenna stuffed into about a foot and a half of coil. __________ But that self-resonant coil is not the electrical equivalent of a 90-degree linear antenna. A coil by itself is not a very efficient producer of EM radiation, whether self-resonant or not. RF |
