Antenna Feed Lines for Portable Use - Why twinlead isn't necessarily a low loss feed line.

Choke balun  ^pop - Essentially, a choke balun is designed to 'divorce' your antenna from the feed line. if your feed line is coaxial cable then you don't want it to be part of your antenna. you want to be able to deliver all your power to the radiator itself, i.e. 'the antenna'. a choke balun does this admirably

EA6VQ - Open wire feeding and baluns - Discussion about open wire feeding and baluns took place in the Moon-Net reflector.

The K6STI Receiving Loop - This relatively unknown antenna does an amazing job pulling weak low band signals out of man-made noise backgrounds

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.

PA0IB Magnetic Loop antennas - Nice photos of two home made magnetic loop antennas assembling details, covering 3.5 MHz to 10.2 MHz and 11.9 MHz to 32 MHz

Loop Antenna Design - Full-wave loops are very popular antennas. They are especially useful on 80 and 40 meters where they perform well at modest heights

Assembly of the Lightningbolt Quad - One of the best antenna values on the market is the LightningBolt Quad. At about half the cost of a tri-band yagi, you get five band coverage with a single coax feedline and excellent performance from a light, low wind load antenna.

A Tincan feed for 2.45Ghz - Construction details for a simple but effective antenna for 2.45Ghz wireless lan use.

Dish 802.11 Wireless Networking Antenna - This antenna modification is for the IEEE 802.11b networking protocol that operates at 2.4 GHz. It can be scaled easily to the 5 GHz frequency used by IEEE 802.11a by simply scaling the dimensions on the feed can and the excitation antenna to 2.4/5 = 48% of the dimensions shown above.
