How long should my coax cable be.

Coaxial cable dimensions calculator.

This program is provided as is. Actual measured values may vary from the calculated values based on manufacturing tolerances cable assembly length connector performance actual operating frequency and measurement accuracy. Enter db loss of cable per 100 ft. The length of the coaxial cable is the center of many debates that 18 wheeler drivers have over the c.

Here you can see that the total length of cable being used is 19 5m which is 7 half wavelengths taken from the multiple 1 2 wavelengthstable with a single 1 4 wavelength added as shown in the coaxial length calculator. The wire size can range from 16 awg to 12 awg. This is derived for the 2m vhf of amateur allocation 144 mhz 148 mhz. It is thought to be accurate but it is the responsibility of the user to verify the accuracy of.

Enter gain of antenna in dbd. Enter length of cable in feet. Pasternack s coaxial cable impedance calculator allows you to enter the outer diameter dielectric width inner conductor diameter width and either the dielectric constant or velocity of propagation vop values in order to calculate the impedance of the coax. The antenna is designed to be fed with 50 or 75 ohm coax cable of most any length with a balun.

I am feeding it with rg 6 tv foam coax. Clinics of america dot com inc. Bookmark or favorite this coaxial cable impedance calculator page by pressing ctrl d. Distance enter the one way length of the wires in the circuit in feet.

Voltage drop choose the maximum percentage of the source voltage drop. The 75 ohm coax is 216 ft long vf 82 guesstimated and is a perfect 1 4 multible for 17 and 20 meters. Online coax cable loss antenna gain calculator. Properties of popular coaxial cables.

At the desired operating frequency. The calculator says i would gain 1db or less by changing coax. The calculator will only return data for frequencies below the cutoff frequency or fco of the cable. Compliments of the c.

Always check with a coaxial cable vendor for values specific to the type you plan to use. Note that attenuation values are given at 400 mhz but can and do often have significantly different values at other frequencies. This antenna is 140 ohms or so both on 14mhz and 18 mhz. For vhf 2m the center frequency is about 146mhz.

It is recommended not to exceed a voltage drop of 5. I was thinking of using rg 11 foam. Place a 1 1 balun on the antenna end of the feedline. Cable loss antenna gain calculator.

Enter power into cable in watts. It is best to use coax in multiples of 25 50 or 1 wave length of the center frequency of the antenna you are connecting to. A calculator to determine the proper length coax to use in your vehicle. This is typically in a raceway cable tray or conduit in a cable burried in the earth or in open air.

The measurements below are for building a simple dipole antenna. To determine the proper length of coax.
