• Build your own HF balun - A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the coaxial cable to one side of the dipole, and the shield to the other. Wrong!

• When and Where to Use Baluns - Baluns are usually used by Hams to feed dipole antennas with 50 ohm coax and to transpose from ladder line feeding a multi-band antenna to the unbalanced input of an antenna tuner.

• KC0KJF Doble Bazooka - The Double Bazooka Dipole is a very efficient single band antenna which is very quite,and does not require the use of a balun. This antenna consists of coax (RG58) with the shield split at the center and the feedline attached to the open ends.

• Classic Multiband Dipole - The Classic Multiband Dipole Antenna QST article. The open-wire feed line dipole antenna is easy to install and offers surprising performance on several bands. You can install it in almost any configuration; it does not have to be strung in the traditional horizontal flat top

• The Gamma Match - The gamma match was originally invented as a means of feeding vertical monopole antennas for medium wave broadcasts, which were earthed at the base for lightning protection- Hams are more likely to use a gamma match to feed a dipole or loop element, but the basic theory is easier to understand for the case of a quarter wave monopole.
