Testing Dipole Antenna and Radio Mod

Not content with just modding my radio today to give it an external antenna socket, I had to go and build an antenna to try it out!

The washing line in the garden seemed like the most obvious place to put it as it’s quite high off the ground. This gave me about 13m to play with for a dipole, with an effective frequency of about 23MHz. Since my current radio doesn’t go as high as that, I instead used the antenna as a halfwave dipole, where it becomes useful at around 11.5MHz. This was quite a rough-and-ready experiment so I didn’t bother with matching or baluns or anything like that; I just plugged that bad boy in. Continue reading
