Beam antennas focus radiation and sensitivity in one direction, allowing you to make contacts further away. What could be more simple In addition, shortening elements generally also means giving in on performance. A disadvantage of multi-core cable is that moisture seeps through the entire cable due to capillary action, resulting in copper corroding. Solder one side of the RG-58 to a driven element and the other to the opposite driven element. Both dipoles can be fed with a single 50 ohm coax cable, without any matching network.
