Online Coax Cable Loss / Antenna Gain Calculator. Enter dB Loss Of Cable Per 100 Ft. At The Desired Operating Frequency. Enter Length of Cable in Feet. Enter Power into Cable in Watts. Enter Gain of Antenna in dBd. This program is provided "as-is".
Suitable for higher power (~1800 watts) at HF. 9913 and LMR-400 are popular “low-loss” RG-8 types. Suitable for VHF (~1.5dB loss per 100 feet at 146 MHz). The flexible types (9913F and LMR-400UF) are preferred, particularly for rotatable antennas.

Below is a simple coax loss calculator which originally appeared on the QST website. Commonly used coax properties are predefined in calculator so all you have to do is select the coax you’re using, the length and frequency, and finally the SWR of your antenna.
So at a given frequency, if you are using exactly a 100 foot length, you would incur a loss of however many db's the manufacture states. Here is a chart of the losses for the most common types of coax used for CB service: Coax Attenuation (*) Velocity Factor Description.
2 lis 2017 · The figures have been calculated by looking at the feeder loss in dB/100m. These figures are a guide and provide the typical power (loss) seen for these coax types.
RF coaxial cable loss formula. Following RF coaxial cable loss formula is used in this calculator is also mentioned. The cable Loss consists of conductor wire loss, insulation loss and connector loss.
