BNC Cables For Front Projectors.
Mike Fitz
D50Q. I completely overlooked the need to use BNC cables between the projector
and the line doubler and know nothing about them. I did a search using
DejaNews and learned that they should be 75 ohms but thats about it.
The store I bought the projector is using regular video cable with BNC
converters plugged on the ends. Is this the best way to do it? Or are there
dedicated BNC video cables available? If anyone care to recommend a brand or a
place to purchase them I would be grateful.

One point to consider is how long a cable run you envision.
I don't like RCA connectors (due to impedance problems), but that's my bias
from being a microwave engineer at the Electronic Defense Labs.
What I would do is buy a roll of quality RG-6 cable (e.g. Belden), a bag
of BNC crimp-on connectors, and a crimping tool at some consumer-friendly
electronic store such as a Fry's Electronics (but I don't know if they have
any outlets in Dallas). FOr a total of approx. $50 or less you could make
your own custom-length cables that will as well as (or better) than anything
you could buy ready-made. A crimping tool is about $7-10, a bag of 10 BNC
connectors should be around $5, and a 100' hank of RG-6 cable about $20-30.

Mike,
For best results do not use adaptors,use BNC cables. Extron makes
particularly good RGB cables. You will need a 5 wire cable.

price too. I use them with my CTX computer monitor (uses DB15 or BNC) ;)
Color separation/satuarion is improved with BNC video connection.

computer parts. The BNC cables sold by my local Best Buy are for
ethernet networks and are RG-58 which is 50 ohm. You want 75 ohm cable
for video and that is commonly RG-59, less commonly RG-6 (which has
better shielding I believe). I buy RG-59 cable with BNC connectors
from a local electronics parts store. The price is about $10 for 10
foot lengths. Or, as another poster pointed out, you can roll your
own.

Or you can call Markertek or HAV (Hudson A/V) and get high quality
Canare BNC cables made in custom lengths for a few bucks more than
making your own.
