Although some of my amateur radio friends will call KD0RVY's "2m Ladder Line J Pole" a "Slim Jim", the basic idea given in this well-done video is sound, doable, and extremely useful for portable, emergency, and field operations. KD0RVY takes you step-by-step through the design, construction, and testing phases of this handy, lightweight, and inexpensive antenna. According to KD0RVY, here's a list of the materials needed for this antenna: 60 to 61 inches/152.40 to 154.94 cm of 450 ohm ladder line. A MFJ Ladder Line board with BNC connector. RG-58 or RG-8X coaxial cable. RG-58 or RG-8X coaxial cable with BNC connectors at both ends. BNC Female to SMA Connector. A 2 meter HT. KD0RVY says the SWR for this 2 meter antenna is excellent:  144.000 MHz (1.2:1) and 148.000 MHz (2.0:1). For the latest Amateur/Ham Ra

Simple Ham Radio Antennas--2m Ladder Line J Pole. Post #917.

In this video from KD0RVY, we learn how to assemble and use a simple 2m J-Pole made from 450 ohm ladder line.  This antenna is suitable for a variety of operations, including portable, emergency, and home use.  Although KD0RVY calls his creation a J-Pole, it may be more accurate to call this antenna a "slim jim".  J-Poles are usually bridged at the bottom of the antenna.  In this antenna, the bridge is at the top.  But that's only a minor quibble.  I've built a few of these antennas for 2 meters and they work remarkably well.  Keep one of these antennas in your "Go Kit."
