Buying Guide – How to Choose the Best Coax Cables for Ham Radio

Choosing the right coaxial cable requires understanding key factors like conductor type, shielding, and connector quality to ensure optimal performance for your specific setup.

Conductor Material

The inner conductor carries the signal so material matters. Pure copper or tinned copper offers the best conductivity and low resistance compared to copper clad aluminum. Higher power applications benefit from thicker conductors like 16AWG or 17AWG which handle more current and heat.

Choose pure copper conductors for the best signal transmission especially for long runs or high frequency bands.

Shielding Quality

Shielding prevents external interference from affecting your signal. Double shielding with foil and braid provides better protection than single shielding options. Tinned copper braid resists corrosion better than plain copper and improves durability in outdoor environments.

Opt for double shielding with aluminum foil and tinned copper braid to minimize signal loss and interference.

Impedance Matching

Most ham radio equipment operates at 50 ohms so matching impedance is critical to avoid signal reflection and loss. Always ensure your cable is rated for 50 ohms to work seamlessly with your transceiver and antenna systems.

Verify the cable is rated for 50 ohms to ensure proper impedance matching and maximum power transfer.

Connector Types

PL259 UHF connectors are standard for ham radio but check compatibility with your gear. Nickel plated brass shells with gold plated center pins resist corrosion and ensure reliable electrical contact. Clamp designs often provide stronger connections than crimp types for heavy use.

Look for connectors with gold plated pins and nickel plated brass to ensure durable and corrosion resistant connections.

Jacket Material

The outer jacket protects the internal components from physical damage and weather. PVC jackets are common and offer good flexibility and waterproofing. For outdoor use select UV proof jackets rated for long term exposure to sunlight and harsh elements.

Choose waterproof UV resistant jackets for outdoor installations to extend the lifespan of your coaxial cable.

Signal Loss Ratings

Lower loss means more power reaches your antenna which improves transmission and reception. Compare loss at specific frequencies like 450MHz to gauge performance. Shorter runs are less sensitive to loss but high frequencies demand low loss cables.

Prioritize cables with low loss specifications especially for VHF UHF bands and long distance installations.

Cable Flexibility

Thinner cables like RG58 are easier to route through tight spaces than thicker RG8X options. Consider your routing path and whether flexibility is more important than raw performance. Stiffer cables may require support brackets on vertical runs.

Select thinner more flexible cables for mobile or compact installations where routing is difficult.

Application Specific Needs

Mobile setups often prioritize flexibility and short lengths while base stations need durability and longer runs. Marine environments require extra waterproofing and corrosion resistance. Identify your primary use case to narrow down the ideal cable type.

Match your cable choice to your specific application whether mobile stationary or marine for optimal results.

How to Use and Care for Your Coax Cables for Ham Radio

Proper installation begins with measuring the exact length needed to avoid unnecessary coiling or excess slack. Use cable ties or clips to secure the cable along its path ensuring no tight bends that exceed the minimum bend radius.

Connectors should be attached carefully using proper tools or select pre-made cables if crimping is not an option. Check all connections for tightness and inspect gold plated pins for any visible corrosion before final assembly.

Regularly inspect outdoor cables for wear or UV damage and replace as needed. Avoid dragging cables over sharp edges or exposing them to extreme stress during antenna adjustments or storms.
