Coaxial-Cable Trap Dipole  ^{updated  pop} - An Attic Coaxial-Cable trap dipole for 10, 15, 20, 30, 40, and 80 meters

50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

Double bazooka coaxial dipole antenna  ^pop - From WH2T Dr Ace's Double Bazooka Coaxial Dipole

EH antenna power lost considerations - Out of Balance Current or Longitudinal Mode Current in the Coaxial Cable causes radiation from the coax. But how large a proportion of the total power is radiated or lost from this Current?

EH antennas and CFA antenna - Many antennas function because of common mode currents, rather than working in spite of them. Two popular examples are CFA and EH antennas. Another recent example, appearing in Antennex's compact antenna articles, is a thick stub "vertical" with no counterpoise.

Cebik Moxon Rectangles - The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.

The Lattin 5 Band antenna  ^pop - The antenna was named for W4JRW who invented it and holds a patent on the basic principle and uses quarter wave stubs, 80, 40, 20, 15 and 10 meter bands

160/80m Coaxial Receiving Loop Antennas  ^pop - Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.
