RG8X BNC cable for RF test and antenna use

This 20-foot coaxial lead uses RG8X construction with BNC male connectors on both ends and a 50 ohm impedance. It suits hobbyists, technicians and engineers who need a reliable link between radios, antennas, oscilloscopes, spectrum analysers or signal generators. The pure copper centre conductor and 95 percent tinned copper braid give efficient, stable signal transfer. A 2.2 inch adhesive tube secures each connector so it resists accidental pull-out.

Attenuation and VSWR limits at 1800 MHz

Measured loss is 2.65 dB over 25 feet at 1800 MHz, so the 20-foot length runs slightly lower. VSWR stays at 1.15, meaning reflected power remains minimal across the band. The cable handles typical HF, VHF and UHF amateur or commercial RF paths, but longer runs or higher frequencies will exceed acceptable loss budgets. Buyers needing lower attenuation over distance should consider larger diameter coax instead.

Waterproof jacket and reinforced ends for field work

The PVC sheath is waterproof and oxidation resistant, allowing permanent outdoor installation on masts or rooftops. The 2.2 inch adhesive heat-shrink tubes bond the BNC bodies to the cable, preventing the connectors from working loose under vibration or wind load. No adapters, tools or software are bundled; the cable is ready to connect any equipment that presents a BNC female port.

Questions about this item

Will the 20 ft RG8X BNC cable reach my antenna without adding another coaxial section?

The cable is 20 ft long with BNC male connectors on both ends, so it connects directly between two BNC ports.

How can I verify the 50 ohm RG8X jumper is passing signal cleanly after I connect it?

Check for a stable VSWR near 1.15 and low attenuation around 2.65 dB at 1800 MHz using an analyser or oscilloscope.

What connectors and shielding come on this RG8X coaxial lead?

It has BNC male plugs at each end, a pure copper centre conductor, 95 % tinned copper braid and a waterproof PVC jacket.
