Thats not the problem. Most of the time I operating in Red Cross Shelters and the Radio and antenna are going to be in close proximity. Last year, I was at a shelter during a hurricane and the antenna had to be indoors. In theses situations, I need High power to get throught the walls of the shelters. Any Ideas. There's more than one way to reduce the level of stray RF inside the case. If you're using an omnidirectional vertical, you'll have a null on the radiating element's axis. If you can elevate the antenna that should help. If you can achieve some measure of horizontal separation as well, that will also help. The ferrite beads won't be wasted either, as they will add a lot of loss to the RF flowing down the power line and the microphone cable without affecting the DC current or the audio tones. And if push comes to shove, there's always the steel toolbox to fall back on. -- To design the perfect anti-Unix, write an operating system that thinks it knows what you're doing better than you do. And then adds injury to insult by getting it wrong. - esr |
