VIDEO CABLES
Miniature coax that features exceptionally low attenuation
for its type while maintaining a reduced size and weight.
All utilize a pure copper center conductor, low-loss
foam polyethylene dielectric, and broadband foil
and braid shielding. VDM230 features the same
gas-injected dielectric found in the HD coax
series making it ideal for Standard Definition
digital video, AES3id digital audio, or High
Definition digital video interconnect within
mobile production trucks. VDM250 and
VDM250D are recommended for short
distance, low bit-rate digital, analog
video, or SVHS applications.
