Your Best Coax Cable for Outdoor Antenna Questions Answered
What Is the BEST COAX CABLE for OUTDOOR ANTENNA to Minimize Signal Loss?
To minimize signal loss (attenuation), I recommend choosing an RG6 cable with an 18 AWG solid center conductor and verifying it is rated as “low-loss” or swept to 3.0 GHz. Shorter cable runs naturally have less loss than longer ones, but for runs exceeding 50 feet, the quality of the dielectric and shielding material becomes crucial. Cables like those from THE CIMPLE CO excel here by maintaining signal integrity over distance.
Is RG6 or RG11 Coaxial Cable Better for Outdoor Antennas?
In my experience, RG6 is sufficient and preferred for the vast majority of residential outdoor antenna installations, especially those under 150 feet, due to its flexibility and lower cost. RG11 is primarily used by professionals for extremely long runs (over 200 feet) where the slightly lower attenuation justifies the much higher cost and difficulty in handling the thicker, stiffer cable. For value-conscious buyers, RG6 is the clear choice.
How Important Is Shielding (Dual, Triple, or Quad) for Outdoor Coax?
Shielding is vital for rejecting interference from external sources like cell phones, radio towers, and power lines. For general use, I find that dual or triple shielding (like the RELIAGINT model) offers adequate protection. However, if you live in a dense urban environment with heavy electromagnetic noise, investing in quad-shielded cable (like the GE option) is worth the money to prevent intermittent signal issues.
Do I Need Specialized Connectors for Outdoor Coax Installations?
Yes, absolutely. Standard screw-on connectors are prone to moisture ingress and corrosion, which quickly degrades the signal and lifespan of your cable. I always recommend using compression connectors that utilize internal weather seals or O-rings. These create a watertight barrier against the elements, ensuring a reliable connection for many years.
Can I Use Standard Indoor Coax Cable Outdoors Temporarily?
While you can use standard indoor coax cable outside temporarily, I strongly advise against it for anything longer than a few days. Indoor cables lack the UV-resistant and weather-stabilized outer jacket, causing the plastic to crack, harden, and expose the shielding and center conductor to moisture. This rapid degradation will quickly lead to signal loss and the need for a costly replacement.
