Verticale 10 MHz homr brew
Antenna verticale 30M 10MHz home made
Why I Don't Like Trap Antennas
So let me tell you why I choose or design antennas the way I do
Wire trap for 12m WARC band
Wire traps are cheap, easy to assemble in a reproducible manner, but can be mechanically fragile easily deformed , good for permanent operation, on dipoles, inverted-V's etc
Inverted-V Antenna for 3.5, 7, 14, 21 & 28 MHz
Trap-style Inverted-V Antenna for 3.5, 7, 14, 21 & 28 MHz i.e. 10 to 80 metres
20m L/C trap on Fritzel isolator
Calculated resonance 21.995 MHz but in practice it’s around 21.600 MHz
