How do I allow high speed data into the enclosure while still stopping/shielding the RF signals?
A. This is a conundrum – allowing high speed data (which actually is nothing more than a ‘specially’ modulated RF signal) and stopping RF signals. Electrically and physically, this data and RF are essentially the same beast and there is no way of stopping one while allowing the other. For example, one cannot filter the data lines on a RJ-45 LAN connector since that would capacitively load the data lines, and so severely distort and attenuate the signal that data communication would fail. One is trying to filter the RF from traveling along the same lines while allowing the data to flow unimpeded – and since the data is at RF speeds, we cannot do one without affecting the other! If one is able to use a very slow data rate, ie: 10 Mbps or so, a filtered DB-9 connector (100pf should be good) may be used with an RJ-45 adapter on each side. This allows the filtered DB-9 to attenuate the RF signals while allowing the (slow speed) data to pass somewhat unaffected (yes, the data lines will have
