Characteristics of the RG-8/U cable (TZC 500 32)
RG8/U-TZC 500 32 Low Loss Coaxial Cable is based on the proven RG8 cable, but with lower attenuation and better shielding. These improvements are achieved by using a foamed dielectric and double shielding.
constructively cable RG8/U-TZC 500 32 consists of:
– One-piece central core with a diameter of 2.74 mm made of aluminum wire with a copper coating
– internal dielectric made of foamed polyethylene with a diameter of 7.24 mm.
– the first shielding layer made of aluminum foil
– second shielding layer – braiding with 85% tinned copper filling
– Outer protective sheath made of polyethylene (PE) with a diameter of 10.2 mm
Wave resistance: 50 ohms

It's hard to imagine my work without a reliable cable. Many times came across flimsy and not hard enough. Or, conversely, inflexible. There were also problems with delivery because it was delayed. This online store does not have such problems, I recommend it to everyone who deals with radio networks.
