A Lowband Antenna that is Almost Free  ^pop - The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.

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

8 Element Quad for 145 Mhz  ^pop - 8 elements quad antenna for 2 meters band, centered on 145 Mhz

The Double Bazooka Antenna - 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) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends

Shortened Center-Fed Half-Wave Dipole - Design your owm HF shiortened dipole

How to make an end-fed antenna work  ^pop - Here is a sure fire way to make end-fed halfwave antennas fed with a 50 ohm coupler work - without long radials, grounds, chokes, voodoo.

End fed halfwave antenna and matching unit - One is an EFHWA for 20-40 meters, and the other is a matching unit for the antenna by n0lx

End-Fed Halfwave Antenna  ^pop - The end-fed halfwave antenna is a resonant half wavelength long antenna like a dipole antenna except for it is fed at its end rather then in the center. This antenna is as old as radio and is probably best known as the Zepp Antenna

Types of multiband antennas - Types of multi-band antennas for the HF bands, from the horizontal end fed wire, to g5rv, log periodics, trap dipoles, vee beams and rhombic antennas.

Windom off center fed antenna 80-10 mt - This antenna is not a true Windom, but rather an off center fed or OCF dipole works on 8 bands from 80 to 10 meters

All HF Band Antennas - F6ITV consideration on HF Antennas, from trap wired anternnas, to center feed antennas.

Field-Deployable Antennas - Resonant dipoles, the W3EDP and end-fed wires, the extended double zepp, non-resonant doublets, and the "Zip-Cord Special" , the W6MMA vertical.

NorCal Doublet Antenna - A simple antenna that can be erected very fast, only need one center support, and do not take up much storage room. Works from 40 to 10 meters band

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.
