Ham radio coax cable loss chart. Attenuation is measured in dB.

Ham radio coax cable loss chart. Loss is a length multiplier, so a 200 ft length would have twice the loss shown above and a 50 ft length would have half the loss. Coaxial Cable Capacity (Maximum Power Rating) in Watts Many power and attenuation calculations are taken from the Times Microwave Systems online calculator 9913 and LMR-400 are popular “low-loss” RG-8 types. 405” Type II jacket is non-contaminating and UV-resistant, suitable for outdoor use The following charts measure the attenuation (loss) of different types of coax at 50 and 100 foot lengths for each of the amateur radio bands. Attenuation is measured in dB. Coaxial Cable Capacity (Maximum Power Rating) in Watts Many power and attenuation calculations are taken from the Times Microwave Systems online calculator. However, stranded center conductors have a little higher loss than solid ones. 9913 and LMR-400 are popular “low-loss” RG-8 types. Suitable for VHF (~1. LMR® is a registered trademark of Times Microwave Systems. Values indicated are approximate and for comparison purposes only. This multiplier factor is why you should keep cable installation lengths between radios and antennas as short as practical! DXE-213U 50 ohm Cable Solid Polyethylene Dielectric Okay for repeated bending Recommended for Rotator Loops . 5dB loss per 100 feet at 146 MHz). The flexible types (9913F and LMR-400UF) are preferred, particularly for rotatable antennas. It is of importance when making decisions about getting the right coax for your Ham Station to understand that there are trade-offs that have to be considered between transmitter power, antenna gain, coax loss, erp, and your total Ham Station system performance. qpatod pwzpr xtv vjxqe bsxr hhiqmo ljzja cch zya uadb
