This 2-foot Superbat jumper cable uses RG58 coax with 50 Ohm impedance and UHF male PL-259 connectors. The connectors are brass with nickel plating, providing durability and corrosion resistance. The inner conductor is tinned copper for improved conductivity, and the contact points use tin plating for reliability. The cable is designed for fulfillment in SWR meters, antenna analyzers, dummies, and HAM/CB radio setups, offering a balance of reach and low loss for stable measurements and signal transmission.
Product Section: exgoofit PL259 UHF Male to Male RG58 Coaxial Cable, 12 inch UHF Jumper Cable and SO239 Female Coupler for HAM & CB Radio, Antenna Analyzer, Dummy Load, SWR Meter
This exgoofit package includes a 12-inch RG58 coax jumper with two PL-259 male ends and a separate SO239 female coupler, expanding configuration options for your SWR meter and antenna system. The jumper cable uses a tinned copper inner conductor with nickel-plated brass connectors to sustain durable performance over many mating cycles. The dual-connector design provides flexibility when adapting between devices and ensures compatibility with common CB and HAM setups for tune-ups and analysis.
Buying Guide: Key Purchase Considerations for SWR Meter Jumpers
When selecting SWR meter jumper cables, consider these factors to match your needs:
- Impedance and length: Most jumpers use 50 Ohm impedance. Short lengths (6–12 inches) are common for bench use, while 1–2 feet offers more flexibility for in-vehicle or portable setups.
- Connector quality: Look for brass connectors with nickel plating for corrosion resistance and better durability over many mating cycles. Ensure connectors are PL-259 (UHF) compatible with your equipment.
- Conductor material and shielding: Tinned copper conductors and strong shielding minimize losses and interference, improving measurement precision on SWR meters and analyzers.
- Durability: Consider jumpers designed for repeated connections, especially if used in field testing or frequent tuning sessions.
- Compatibility: Verify compatibility with your devices (SWR meters, antenna analyzers, dummies, tuners) and ensure the couplers or adapters fit your setup.
- Cost vs. value: While higher-grade jumpers may cost more, their reliability and longer service life often justify the investment for active hobbyists and professionals.
- Purpose-specific features: Some bundles include extra couplers (SO239) for added flexibility, useful when bridging between different jack types.
In practice, selecting a few jumpers of varying lengths (e.g., 12 inches and 2 feet) provides versatility for portable field work and stable bench measurements. Prioritize low-loss RG58 or RG8x constructions, quality nickel-plated brass connectors, and robust build quality to sustain long-term performance with SWR meters and antenna analyzers.
