Portable Radios use High Voltage Reed Relays Technology

Portable radios are a helpful tool for many people in privat and work situations. Privat people use portable radios for outdoor activties such as climbing or hiking - they need robust and reliable devices. People who work at the police, fire department or in other rescue organisation need also professional equipment. For both application the portable radios must be absolutely reliable and very robuts against external influences like water, dirt or dust - with our hermetic sealed Reed Technology we make this could be happen. A further application for portable radios is the military sector which also appreciate this advantages - Portable radios typically operate between 3 MHz and 30 MHz. These frequencies are relatively low by today's standards when compared to the telephone bands in the 1 GHz to 4 GHz range. However, even as low as 30 MHz the signals will 'ride' on the outside of their conductor (skin effect). When switching between transmit and receive, reed relays have become the design-in choice, because they are hermetically sealed and packaged in a rugged epoxy, making them a good choice for the outdoor environment. MEDER uses copper plated reed switches to minimize skin effect.
