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.

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  ^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

QFH antenna for weather satellite band - This article describes how to make a quadrifilar helix (QFH) antenna easily, from inexpensive materials: uPVC plumbing pipe and RG-58U co-axial cable

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

A two dollar helical hf portable antenna  ^pop - Here’s an easily transportable vertical antenna for 20 meters collapsible to 4 feet that costs about $2.00 to make. This was created as a fun project to demonstrate how to enjoy operating HF in the field with a home-made portable antenna without spending a ton of money. Bev AH6NF (YL) made this antenna, tuned and ready to operate in less than one hour

Ah-4 unofficial home page - Here you can find information on Icom's AH-4 automatic antenna tuner. Check out General Information on the AH-4 Tuner.

802.11b Antenna on the Cheap - Build a 802.11b antenna using PVC, some cheap copper tubing, a Pringles can, and some scrap cardboard, in a few hours. Tests state a 12db gain on 2.4 Ghz

The Copper Duckie Antenna - A super easy VHF antenna for apartment dwellers

Cobra UltraLite Antennas by K1JEK - The alternative multi-band solution, covers more bands than a G5RV, light weight, won’t damage your trees.

Hidden transmitter hunting - Interesting t-hunting projects, from antennas to audible smeters

A low power 3.5MHz ARDF transmitter - This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferrite-rod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.
