    DX Engineering Multi-Band Dipole Antennas

    DX Engineering Multi-Band Dipole Antennas are designs that are rugged, yet lightweight. Using a tuner, they are usable to 30 MHz and come complete with the wire elements, ladder feedline, center T support, and end mount brackets.

    These antennas are built using the highest quality components. They use 14 AWG stranded-copper, PVC jacketed elements for flexibility and strength and 100 ft. of 18 AWG 300-ohm 0.88 Velocity Factor ladder lines that are UV-resistant. Stainless steel hardware is included. 

    Often, a 4:1 balun is suggested for multi-band dipoles; however, the best balun to use for this application is a 1:1 ratio. The 1:1 baluns provide better balance, have lower loss, and are more tolerant to load impedance and balance variations than other baluns. A tuner balun is not included in the dipole antenna kits and is available separately. 

    The dipole center T support has pre-drilled holes for the attachment of the wire elements, feedline, and support or messenger lines. The center support top hole is used for the attachment of a "messenger line" that can be strung above the antenna wire and is used to provide support for the antenna wire and feedline. The use of the messenger line, which is strongly recommended but not included, will reduce the stress on the element wires and keep the antenna from stretching over time, which will change its resonant frequency. This line can be thin Synthetic Textile rope available from DX Engineering, which has a high breaking strength. Ideally, it should attach to the same structure used for the dipole, only above it, forming at least a 30 degree angle between the dipole and the messenger line. For further information and to decide the amount of rope you will need, please read the included instructions and check your wire antenna area of construction.

    When you lack the room for more than one antenna or need a multiband antenna for band agility, consider one of these DX Engineering Multi-Band Dipole Antennas as an elegant and economical solution!
