The
Tower Series cable uses a Low Loss Polyethylene
Foam with very low dielectric losses resulting
in low attenuation of RF power.
Used as antenna feeders, cabling of antenna
arrays, radio equipment interconnections, jumper
assemblies or indoor applications, the Tower
Series cable provide a good solution for many
wireless applications.
