Take the line outside at night where you can hear crickets chirp.
Count the number of times it chirps in 15 seconds, and add 40. Thats the degrees. (temperature). http://www.srh.noaa.gov/elp/wxcalc/f...cketChirp.html Now measure the transmission line, Then get a copy of the ARRL Antenna Handbook or the ARRL Amateur Radio handbook, and find out why you asked the wrong question. "redhat" wrote in message oups.com... what is the electrical length of a transmission line in degree? regards |
