The new VDM260 was designed to achieve exceptionally
low weight and size, without sacrificing the critical elec-
trical and mechanical properties that are required for
reliable transmission in broadcast applications.
The VDM260 features a 26 gage solid conduc-
tor that provides lower attenuation and supe-
rior mechanical integrity compared to other
subminiature designs that utilize smaller,
more fragile gage types.  In addition,
VDM260 has a broadband foil and
braid shield that offers better RF/EMI
protection and greater structural
integrity than serve type shields.
For the insulating dielectric, VDM260
utilizes gas-injected PE which pro-
vides exceptionally low attenuation
and a 4.5GHz bandwidth for HD
video transmission.
