Transmitting Baluns - One of the most popular Ham-lore rumors is a balun's performance can be tested or evaluated by grabbing the coax and watching for an SWR change. This is probably one of the worse test-rumors circulating

The Bazooka antenna - The Bazooka-antenna was developed by the staff of M.I.T. for radar use. The original Bazooka used coaxial cable for the entire radiating elements.

The Bazooka Antenna - Notes on bazooka antennas by Katunk: a portable field antenna, sometimes called the double bazooka or a coaxial antenna.

Choke balun  ^pop - Essentially, a choke balun is designed to 'divorce' your antenna from the feed line. if your feed line is coaxial cable then you don't want it to be part of your antenna. you want to be able to deliver all your power to the radiator itself, i.e. 'the antenna'. a choke balun does this admirably

DirectionalBiQuad - Seattle Wireless - A biquad is a fairly powerful antenna which is relatively easy to construct, with impressive performance for their size. A link greater than 5 miles can be made with a pair of these as a stand-alone antenna and a Prism2 100mW card, provided you keep coax short, and your line-of-sight is clear.
