MFJ-259
Using the MFJ-259 to measure coax length. »
If you need to find the lenght of a coax cable then the MFJ-259 will help you find that. You will need to know the velocity factor of the coax cable being measured. Often times this is a know measurement from the manufactor. Follow the steps below. 1. Short one end of the coax. 2. Connect the other end of the coax to the MFJ-259 input. 3. [...]
Using the MFJ-259 to find a shorted coax cable. »
If you need to find the bad spot (short) of a coax cable then the MFJ-259 will help you find that. You will need to know the velocity factor of the coax cable being measured. Often times this is a know measurement from the manufactor. Follow the steps below. 1. Connect the coax to the MFJ-259 input. 2. Turn on the MFJ-259 and start at the [...]
Using the MFJ-259 to manually find the velocity factor of coax. »
If you need to find the velocity factor of a coax cable manually then the MFJ-259 will help you find that. You will need to have a piece of coax of a know length/measurement Follow the steps below. 1. Disconnect both ends of the coax and measure the physical length of the line in feet. 2. Find the lowest frequency across all the bands at [...]
