Buying Guide

Match impedance to application

Use 50-ohm coax (e.g., RG58-style) for radio and CB antenna runs and 75-ohm for CCTV/video equipment to avoid signal loss and mismatch

Check connector type and termination

Confirm the cable includes the needed connector (PL-259, BNC, or manufacturer-specific Starlink plugs) or allows easy termination for your device

Prioritize waterproofing for outdoor runs

Choose cables with waterproof jackets or IP-rated connectors for roof-mounted satellites and outdoor surveillance to resist moisture and UV exposure

Consider length vs. signal loss

Longer runs increase attenuation; select heavier-gauge or lower-loss cable for 50–100ft spans or plan for amplification if needed

Assess build quality and shielding

Look for braided or foil shielding and solid jackets to reduce interference in busy RF environments and improve long-term durability
