FreeLists / si-list / [SI-LIST] Running analog video on micro-coax

[Joel Brown <joel@xxxxxxxxxx>]

We have an application which requires running 75 ohm analog video over 
coax for a distance of 75 Inches.
Conventional VGA cables are much to large and bulky because we need to 
run the cable through hinges and cable retractors.
I have seen some micro-coax products from several companies which use 
very small diameter cable.
However all of the micro coax products are 50 ohm and seem to be 
targeted for digital signals such as LVDS.
One approach I am considering is to use a buffer amplifier to receive 
the 75 ohm signal and then redrive it on the 50 Ohm cable.
The only drawback is possible signal distortion from the buffer 
amplifier. The signal bandwidth is 100 MHz.
Any thoughts or ideas would be appreciated.
Thanks - Joel
