This article was reprinted to assist new hams at building their own 2 metre antenna. This design is very rugged and can be built for a few dollars with most of the parts available at your local Home Depot. -
-
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. -

Based on a W4TWW project and modified by KN4LF -
If you have ever tried transmitting on HF from a tall block of apartments, where it's just not possible to erect a substantial aerial system, then this article is for you -
This project describes an ARDUINO based automatic antenna tuner, for an end-fed half wave (EFHW) antenna, working on 20 & 40 meter bands -
-
A Bencher antenna divsion, manufacturer of HF YAGI and Vertical antennas -
A pedestrian antenna is considered to be a lightweight antenna that can easily be carried to the shootout by one person in a backpack or bag. -
The page provides detailed instructions on how to build a double bazooka antenna for the 40 meters band. It includes information on materials needed, measurements, and assembly steps. The antenna can be configured as an extended dipole or an inverted V, offering low noise, wide bandwidth, and a 1:1 standing wave ratio. The content also offers calculations for other bands and includes photos of the antenna fabrication process. -

SuperAntenna offer Portable, Stealth, Mobile, Base, Backpack, EmComm, Ham Radio, Marine, MARS, CAP, HF SSB, Gov, NGO and Commercial antennas -
Here are construction plans of a Turnstile antenna that I use for space communication on the 2 meter amateur radio band. -
Amateur quarter wave ground plane antenna calculator, calculate vertical and radial length -
This project is about a cheap way of building a colinear antenna for VHF 145MHz, and having about 10dB more gain than that little 1/4-wave magmount -
This is a vertically polarized Phased array. The left Vertical wire is 180 degrees out of phase -
This Field Day Vertical Antenna project is the result of many years of attending various field day sites and realizing that what was needed is a simple, easy to assemble vertical antenna. -
A simple T-network that can match any unbalanced antenna system by AA5TB -
-
The terminated tilted, folded dipole T2FD is a little known antenna that performs excellently. Compact in size compared to a half-wave dipole the T2FD provides signal gain, wide frequency coverage, and exceptionally low noise characteristics. -
Calculate your dipole, 3 element yagi and a simple dipole -
These devices are called Traps, but they are actually more like frequency sensitive switches. They are parallel resonant, high Q, tuned circuits which provide a very high impedance at their frequency of resonance. -
Easy Eggbeater Antenna for amateur radio to work with Satellite VHF & UHF -
The IK-STIC 2 is a vertical, all band, antenna that is over 25 feet tall yet weighs under 5 pounds. Based on a telescopic pipe or a fiberglass fishing pole, using a tuner it can easily cover the amateur radio HF bands from 40 - 10 Meters -
What type of antenna should I get? Well, the best type of antenna for working the OSCAR satellites are circular polarized antennas -
VE7CA reprint an interesting article taken from arrl antenna compendium. Two elegant practical and portable 6-meter gain antennas, a two-element quad and a tree-element Yagi antenna for 50 Mhz-6 meter band -
