Frequently Asked Questions - RG-8USYS Viakon
What is the impedance of the Viakon RG-8USYS cable?
The Viakon RG-8USYS is a 50-ohm coaxial cable, standard for most RF applications.
What connectors are compatible with RG-8USYS?
Common connectors include PL-259 (UHF), N-Type, BNC, and SMA (with adapters). Ensure connectors match the cable diameter.
Can I use RG-8USYS for outdoor installations?
Yes, the PVC jacket is UV resistant and suitable for outdoor use. However, avoid direct burial without additional protection.
What is the maximum frequency for this cable?
The cable is rated up to 1 GHz, making it suitable for VHF/UHF and some lower microwave bands.
How do I strip and prepare RG-8USYS for connectors?
Use a coaxial cable stripper for RG-8 size. Strip approximately 1/4 inch of jacket, then trim the dielectric to expose center conductor, and fold back the braid carefully.
What is the power handling capacity?
At 30 MHz, it can handle up to 1000 watts (PEP) with low SWR. Derate at higher frequencies.
Is this cable flexible for tight spaces?
The minimum bend radius is about 50 mm (2 inches). It is moderately flexible but avoid sharp bends to prevent impedance mismatch.
What is the velocity factor (VF) for RG-8USYS?
The velocity factor is 82%, meaning signals travel at 82% the speed of light in the cable.
How does RG-8USYS compare to RG-8X?
RG-8USYS has a thicker conductor and lower loss than RG-8X. It is less flexible but better for longer runs.
What is the jacket color and marking?
Typically black jacket with white printing indicating Viakon RG-8USYS and impedance rating every few feet.
