• DM9EEs info site on FCP - folded counter poise (Radial) - No space for 120 ground radials, nor 4 elevated radials ? Give the FCP a try. Itcan be your solution to get on topband. Or even build a 4 square on a city lot.

• J-Pole theory  ^pop - The J-Pole antenna is an omnidirectional antenna that can be used for base, mobile and field day stations. It does not need a ground plane, radials or a complicated matching system. The J-Pole can be cheaply, simply and quickly constructed using a variety of techniques, some of which are discussed in this article.

• Challenger DX Antenna Review by NK7Z - A review of the GAP Challenger DX Antenna that is not a traditional 1/4 wave vertical, but is a vertical dipole, this gives it several advantages over a standard 1/4 wave vertical, mainly the reduced number of radials, with excellent performances.

• Troubleshooting Traps - This article refers mainly to the old Cushcraft 1/4 wavelength AV series of antennas (12AVQ, 14AVQ etc) hence the references to radials. The R series (R5, R7 etc) are 1/2 wavelength antennas, and the radials are NOT 1/4 wavelength resonant.
