- Page 2 Introduction The DX Engineering Multi-Band Dipoles are designed to be rugged yet lightweight. Using a tuner, they are usable to 30 MHz. They come complete with the extra length wire elements, 100 feet of premium 300 Ω ladder feedline, Center-T support (U.S. Patent No. 7,764,244), and end mounting insulators (U.S. Patent No.
- Page 3 Multi-Band Center Fed Shortened Dipole using Ladder Line Feedline The DX Engineering Multi-Band Dipoles include 100 feet of high quality legal limit capable 300 Ω ladder line. Depending on your specific installation, this feedline will need to be shortened or lengthened. The optional DXE-LLC-1P Ladder Line Couplers can be used for connecting ladder line together for lengthening the ladder line.
- Page 4 Changing the length of the ladder line will alter resulting impedances so the tuner should be able to reach a certain frequency that was giving it trouble. The coax from the DX Engineering 1:1 Balun to the tuner should be kept short; typically 5 to 15 feet is best.
- Page 5 80 meters. The 80 meter band starts at 3.5 MHz. Therefore, 123/3.5 = 35.1. DX Engineering 300 ohm ladder line has a velocity factor (VF) of 0.88, so 35.1 x 0.88 = 30.9 ft. per 1/8- wavelength. If 90 feet is required to get to your balun mounting position, the nearest odd multiple 1/8 wavelength length is 92.7 feet (30.9 x 3).

Refer to Table 1 for details on ladder line lengths.
- Page 7 If you need additional feedline, the optional DX Engineering DXE-LLC-1P Ladder Line Coupler can be used to create a strong and consistent splice. See Figure 2. Figure 2 - DXE-LLC-1P Line Coupler Element Wire Lengths Determine the length of the element wires needed for your particular antenna design. Refer to Table 1 for details on element wire lengths.
