RG214 is one of the most popular RG cables.
For economical reasons and when thermal
conditions allow it, this cable may be used
instead of RG393.

This LMR400 type 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.
