My new RG58 coaxial cables

Here are a pair of my new RG58 coaxial cables, both 15m long. One has pre-crimped PL259 connector at one end only while the other has pre-crimped PL259 connectors on both ends.

RG-58 is a very common type of 50-ohm coaxial cable often used for low-power radio frequency (RF) and signal connections. This impedance is the standard for most two-way radio communications and data applications. Outer diameter is approximately 0.2 inches (5 mm), making it relatively thin and flexible. It has a central conductor which either solid or stranded copper wire. Stranded versions like RG-58A/U are more flexible. Dielectric (insulator) is often Polyethylene. Outer conductor/shield is typically a braided tinned copper shield. Outer jacket is often made of PVC. It may be considered for frequencies generally up to around 1 GHz or even 3 GHz, but attenuation (signal loss) increases significantly at higher frequencies, making it best for moderate frequencies and short to medium runs. It can be terminated with BNC (Bayonet Neill-Concelman) connectors, TNC, N-Type, or PL259/UHF connectors. Earlier RG58 was also used for Ethernet connection, but now it is replaced by CAT5/6 cables. RG58 has higher loss compared to thicker, low-loss cables like RG-8 or LMR-400.
