Superbat RG58 Coaxial Cable 50 Ohm Coax Cable 20 Feet (6.09 Meters)

This coax is very good and very flexible. I am quite happy with it. I was using it for a rather precise transmission line tranformer application, and I needed to know but I could not find anywhere in the product specs what this coax's velocity factor is, so I measured it using a NanoVNA. For those who may be wondering, the measured value of velocity factor on the cable that I received is 66.3% - which corresponds nicely to the expected 66% VF standard for RG-58 A/U with PE dielectric and PVC jacket.

Very fast seller response. The cable arrived within 72 hours of my placing the order. It arrived as a shrink-wrapped coil of cable in an Amazon branded padded paper shipping bag. Nothing fancy, but fine for the purpose. I have used this before, primarily for making jumper cables and short runs of cable to use in the radio shack. Generally, i restrict signals to no more than 200 watts or 30 MHz to keep any losses at a minimum. It can be used (and I have used it) for modest (50 feet or less) runs for frequencies up to 144MHz, but with increasing loses within the wire. That’s not the fault of the wire, you just need a different cable for the efficient transmission of VHF and above frequencies over any significant distance. The stranded center conductor allows the cable to be moved and re-routed with minimal chance of breaking the center conductor and causing a hard-to-trace issue. It works as designed and I will buy more if required.

Supple soft cable, insulation not very heat resistant. Made up a cable with it using BNC crimp on connectors. Checked cable for short circuit after assembly, was good. Used heat gun on shrink tubing at each end and cable shorted from center to ground conductor where the connector was crimped on.

I measured it. The published specs hold up. I bought this spool to build my own BNC test cables and, rather than take the listing on faith, I characterized a 23.175 m length on the bench. Capacitance: 101.0 pF/m measured, against 101.05 pF/m published. That one is as confirmed as it gets. Center conductor: 37.1 mΩ/m by four-wire measurement. Annealed copper at the stated 19 × 0.18 mm calculates to 35.7 mΩ/m; add stranding lay and tin plating and you expect 36–38. Copper-clad aluminum would have landed near 55. The tinned-copper claim is true, which at this price I was not taking for granted. Shield: 0.442 Ω end to end, or 19.0 mΩ/m. That inverts to roughly 1.9 times the copper cross-section of the center conductor. A substantial braid, not a token one. Dielectric: measured dielectric constant 2.28 — solid polyethylene, as claimed. Velocity factor: 0.6555 ± 0.0036, from the resonance nulls of open- and short-terminated lines swept between 2 and 19 MHz. An independent determination from inductance and capacitance gave 0.6547. The two methods agree to 0.12%. Characteristic impedance: 50 Ω. The cable is flexible and terminates cleanly with standard crimp connectors. One caveat, in fairness: this is a single spool measured by a single buyer, and it says nothing about lot-to-lot consistency. But on the reel I received, every published specification survived measurement.

Buen producto buen material

Beware - minimal quality in this wire build. I used this to make small (8" - 12") pigtail extensions for adding height my cell phone boost antenna, so these will be INSIDE the antenna extension poles so Im not worried about shielding quality but if I was running this to be exposed I would look for a much higher quality wire. Also, you should expect to tin/solder the conductor as it it small strand, not solid.

Needed a specific type of RG58 cable for a project. This is solid polyethylene with a stranded center conductor. The sellers description was perfect. Would but from again.

What can i say? Its rg58, loss is its middle name but this stuff was acceptable especially for the cheap price.

Muy buen cable rg58a/u. Se ha utilizado para una antena t2lt para cb27 y funciona realmente bien, consiguiendo una roe 1.1 en la frecuencia deseada. 100x100 recomendado.

Sehr günstiges Top Kabel

OK.

Bon rapport qualité prix

Stevige coaxiaal kabel met een getwiste kern. Prima voor patch snoertjes te maken.
