We worked up to 40 meter with very high quality video cables (separate
cables for RGBHV). If you need long distances and high bandwidth (e.g.,
2048x1180_72 gives 174Mpixels/sec) consider the ultra-high quality
videocables that are used for camera's in the television industry. Just
to mention a possibility (no price info):
DIN 47394 96 IEC/75-17-1 2.7/17.3
{2.7mm copper inner conductor, 22mm sheating, 3.6dB attenuation per
100m at 200MHz!}
This is a very FAT cable but it gives you less than 3dB attentuation
with 60m length! You have to solve connector problems though. Standard
BNC won't fit to this cable, but you need to convert from 13W3 to RGBHV
single cables anyway.
The cable solution is probably the cheapest if you consider using
multiple channels from your DG5-8 (otherwise consider Lightwave
devices). Cables solutions for mouse/keyboard/serial tend to be
difficult for long distances. You might need something else here, look
into PC terminal switchers.
