160 Meter Antennas at W8JI - 160-meter vertically polarized transmitting antennas center around this 200-foot tower

KE4UYP Linear loaded vertical antenna - This is a vertically and horizontally polarized antenna the Linear loaded 1/4 wave length vertical radiator introduces very little loss for 80 or 160 meters

Dual Band Vertical On Autopilot - A good 20 & 40 meter dual band vertical using a novel tuning method that provides automatic band switching.

40 M. triangular full wave vertical loop

YLRADIO - Full wave delta loop - This Delta Loop is a three-sided antenna suspended high in the air by vertical supports, such as tall evergreen trees. Recommended height is 40 feet or more at highest point, but higher is better.

80 m 3/4 wave LLV - This is a vertically polarized Phased array. The left Vertical wire is 180 degrees out of phase

80m L Antenna. RSBEV's - Reduced Size Broad Elevation Verticals

The Bazooka vertical  ^pop - This is a deviation from the wonderful antenna the Double Bazooka.

Build a bazooka dipole  ^pop - Build Your Own Bazooka Dipole: A VHF/UHF vertical dipole made from coax

Build a 2.4GHz Vertical antenna  ^pop - Building a 2.4GHz vertical collinear omnidirectional antenna

The full-wave loop antenna - These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.

An automatically tuned 7-30MHz mobile antenna - This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.

R7 Vertical Maintenance and Repair - How repair the traps, and then homebrew the rest of the antenna, including the matching box

NEC4WIN - NEC4WIN is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows and can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc. NEC4WIN has limitations. They are the same as Mininec3 on which the engine is based.
