A folded dipole is a dipole antenna with the ends folded back around and connected to each other, forming a loop as shown in Figure 1. magnetic loops are a compromise antenna and performance will be down on a full size wire antenna particurlarly on lower hf bands this article compare this magnetic loop with a full sized wire antenna on 80 meters by vk3ye. You really do need that RG-59.
