(2) PTFE = PolyTetraFluoroEthylene
(3) TPAl = Tin Plated Aluminum
Based on RG405 standard, this cable will
be selected for application requiring easy
conformability and/or application requiring
reduced weight.
Due to the aluminum outer conductor, this
cable can be hand formed with exceptional
ease with no spring back effect.
Cable can be reshaped, eliminating the need
for costly drawings.
The outer conductor material (aluminum)
slightly increases the attenuation compared
to standard RG405.
