What can you do with a bit of speaker wire? You can make a speaker wire doublet, a great low-cost QRP antenna. The speaker wire doublet is an effective multiband Amateur Radio antenna for low power (QRP) field use. The speaker wire doublet along with an antenna matching unit will get you on the air and excite your portable Amateur Radio activities like POTA and SOTA. This HF multiband doublet antenna can be used on all amateur radio bands down to the lowest frequency the antenna is cut for. As this antenna is not tuned to any specific frequency, it is considered a doublet instead of a dipole.
