A simple 2.4 GHz double QUAD Antenna
70 cm Quagi Antenna
This was my first AO-10 antenna. As goofy as it looked, I managed a few contacts with 10 Watts, including Brazil on SSB. This is a pair of 8-element quagi’s, set up for RHCP. Construction is simple, with no critical tuning elements. They are made from 1/2″ PVC pipe and # 10 wire (stripped from
G5RV more ideas
The G5RV multiband antenna is a very popular design on the HF bands. The “common” G5RV is configured as a 3/2-wave dipole on 20 meters, and works as either a shortened dipole, or a collinear-fed long wire on the other bands. In this configuration, the overall length is 102 ft, with a 28 to 34
Beverage antenna information
The Beverage (or “wave”) antenna was invented in the early 1920s by Dr. Harold H. Beverage. It was first discussed in a paper titled “The Wave Antenna – A New Type of Highly Directive Antenna” written by Beverage, Chester W. Rice and and Edward W. Kellogg for the journal of the American Institute of Electrical
3 Eelements Yagi beam for 6 meters
Spacing between elements are 34 and 1/2 inches. The elements are 1/2 inch aluminum tubing of 1/16-inch wall thickness.(you can cut up an old TV antenna they work great). The Boom length is 72 inches (6 feet).The boom is 1 and 1/4 inch tubing. You can attach 50 ohm coax to this antenna after you
20 meters QRP Dipole
This is a portable dipole I built for 20 meters. It works great. The SWR is really low. I would not recommend this for permanent use just because it is not build like a rock. It will do just fine for portable in the field operation. It is a great backpacking antenna. I only used

If you have any interest in antennas at all, fasten your seat belts and hang on to your hats, because what you are about to read here is going to blow you away. Conventional wisdom concerning antenna matching and resonating is about to be shattered and the principles revealed here might just be the start
7 elements Yagi-Uda Antenna for 144 MHz
An original project by I0QM of a 7 element yagi anetnna in a PDF File. The QM7 antenna is a simple 7 elements Yagi with 3.7 m boom length for the lower 144 MHzSSB/MGM band forward gain is 1.35 dBd; i.e. 13.5 dB forward gain over the isotropic radiator, while the F/R is about 12.5
