"thanks Flying High, will check out that person.
yeah I wish to design the antenna from scratch to learn the concept and have more control over the design parameters. there is no video involved yet. "

"i'm sorry yes this has gone a bit off topic. i plan to build my own transmitter and haven't figured out at what frequency i would be transmitting. i have only rudimentary knowledge of antennae design but have worked a lot on power amps. do you think…"

"Sgt Ric thanks for your suggestion. I have read the same about power boosters.Any antennae in your mind? I have to send pulses at low frequency over the said distance.Thanks and regards"

"hi,thanks for having me here. anyone know of any ways to build an amplifier that would achieve this but using discrete components and ICs only? I have a project that asks us to build amplifiers this way. Any good tutorial would be welcome. i am just…"
