I would like to show you how you can make a simple and cheap antenna from 300 Ohm twinlead wire.
Very simple antenna you can make in 10 minutes and is handy to take with you and is better than a rubber duck on your handheld. The gain is about 2.5dBi and costs less than Euro 5.
The J-pole antenna, more properly known as the J antenna, was first invented by Hans Beggerow in 1909 for use in Zeppelin airships. Trailed behind the airship, it consisted of a single element, one half wavelength long radiator with a quarter wave parallel feedline tuning stub. This concept evolved to the J configuration by 1936 attaining the name J Antenna by 1943.
