Frequently Asked Questions About Best Coaxial Cable for OTA Antenna

What is the difference between RG6 and RG59 coaxial cable for OTA use?

RG6 coaxial cable is generally considered the standard for modern OTA TV reception and satellite use. RG6 has a thicker center conductor and superior shielding (often dual, tri, or quad shielded) compared to the older, thinner RG59. Because RG6 is better at preserving signal strength and preventing interference across higher frequencies, it significantly reduces signal loss (attenuation), especially on runs over 50 feet. Always choose RG6 for your antenna setup.

How much signal loss (attenuation) is acceptable in my coaxial cable run?

Signal loss, measured in dB, increases with the frequency of the signal and the length of the cable. While some loss is normal, excessive loss leads to pixelation. A high-quality RG6 cable will typically lose about 5-6 dB per 100 feet at typical UHF TV frequencies. If your total run is long (over 100 feet) or includes splitters, you should use an in-line pre-amplifier mounted near the antenna, or a distribution amplifier (like the Antronix MRA4-8) before the signal splits, to compensate for the anticipated loss.

Can I use the same coax cable for my cable modem and my OTA antenna?

Yes, provided it is high-quality RG6, which is standard for both applications. Both cable modems and OTA antennas require low-loss cable capable of handling high frequencies (up to 3 GHz is standard for RG6, which covers both internet and TV bands). Look for certified cables like the Cable Matters Quad Shield, which explicitly supports modems, satellites, and OTA applications.

Is quad shielding necessary for best coaxial cable for ota antenna reception?

Quad shielding (four layers of protection) provides maximum defense against RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference). While dual shielding is usually fine for short, simple runs, quad shielding is strongly recommended if you live in an electrically noisy environment (near cell towers, large appliances, or power lines) or if you are running the cable inside walls alongside AC power cables.

Should I ground my outdoor antenna’s coaxial cable?

Yes, absolutely. Grounding is mandatory for safety and signal integrity, especially for large, outdoor antennas. The coaxial cable should be routed through an antenna discharge unit (grounding block) before entering the structure. This block must then be connected via heavy-gauge wire to a dedicated grounding rod or the home’s primary electrical ground. This protects against lightning and static electricity buildup.

What are the dangers of using cheap connectors or couplers?

Poor-quality or poorly installed F-connectors and couplers are major sources of signal loss, known as “insertion loss.” Cheap connectors may not be perfectly 75 Ohm impedance matched, creating signal reflections. Additionally, if cheap outdoor connectors lack O-rings or proper compression seals (like the weather-booted ends on THE CIMPLE CO cable), moisture can penetrate, leading to corrosion and permanent signal degradation over time. Always ensure connections are tight and, if outdoors, fully sealed.
