Due to its 75 ohms characteristic impedance,
RG 216 is rather dedicated to TV/Video
application.
This LMR600 cable can be considered as an
alternative to equivalent diameter corrugated
cables.
The main advantage is greater flexibility and
bendability allowing easy routing during the
installation.
The foam dielectric provides excellent loss and
low return loss levels.
The double screen construction (Aluminum foil
+ tinned copper braid) offers a high level of
shielding as well as low leakage.
This cable will be advised for feeder and jumper
assemblies in cellular networks as well as
applications requiring easy routing.
