This is the smallest semi-rigid cable size
proposed by RADIALL.
Its reduced size allows it to be easily
handformable during integration operations.
Due to the outer conductor coating (tin), this
cable will be used instead of standard .047
copper for applications requiring high corrosion
resistance and improved solderability.

This handformable cable is a good alternative
to RG405 for applications requiring an easy
routing on equipment.
Due to the outer conductor construction, this
cable can be hand formed with exceptional
ease with no spring back effect.
Cable can be reshaped, eliminating the need
for costly drawings.
Attenuation is a little bit higher than the
RG405's one but temperature range is wider.
