A magnetic loop for 14-28 Mhz - Descriptio and pictures of a magnetic loop in german

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.

A multi-band super mini loop antenna - To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands

W6ZO Delta Loop - W6ZO Portable Delta Loop for 20 meters

PA0NHC 80/40mtrs dipole antenna - Dipole antenna for 80 to 20 mtrs with END-coax feed by PA0NHC

Loop Antenna for 50 MHz - A magnetic loop antenna using a 28\" bicycle rim for six meter band

HF Home made Balun  ^pop - A balun is a device that is used at the feedpoint of a balanced antenna when an unbalanced feedline is desired to feed the antenna. Balun is a contraction for BALanced to UNbalanced.

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

Wire delta-loop antenna - Description of a delta loop antenna for HF bands in french

Transmission Lines - Whenever you choose a coax feedline, the frequency of operation is a very important consideration. Over the operating bandwidth of the coax the VSWR is low, typically 1.2:1 or better. Insertion loss is also an important parameter. It is usually specified in dB/foot and is a linear relationship.

Transmission Lines - Articles on SWR measurements and feed lines tuning.

Antennas for 136kHz - A very long and exaustive documentation on building antennas for 136 khz. Includes links to antenna design software for longwave

The 5 Bands Wire-Beam - This wire-beam has one radiator-element, feeded with 450-Ohm-Wireman-twinlead and needs an antenna-tuner. For the bands 6m, 10m, 12m, 15m, 17m and 20m bended reflector-elements are used. The support is a cross of 4 fibreglass-fishing-rods

80 Meter Multiband doublet antenna - 80 meter multiband doublet antenna with open wire feedline for 80-10 meters by N1LO

Long Loopstick Antenna - Wound on a 3 foot length of PVC pipe, the long loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground.

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

T-Match Construction - The T-Match with its balanced feed point is one method of feeding a Balanced Dipole.

XLZIZL by AC6LA - XLZIZL is an Excel application that analyzes the components of an antenna feed system, including transmission lines, stubs, baluns, and tuners. Calculations include impedance transforms, SWR and reflection coefficient, power loss, voltage and current standing waves, stress on tuner components, network attenuation (S21), and return loss Analysis results are available in worksheet format and in five different chart formats, including Smith charts.
