Random Wire Antennas using the LDG 9:1 UnUns

Image
The random length wire antenna is one of the most popular antennas available to radio amateurs.  Coupled with a 9:1 UnUn, a decent counterpoise system, and an "antenna tuner", you can work the world with a convenient length of wire.

In this video, Peter (G3OJV) from the Waters & Stanton Video Channel discusses the theory and practice of random length wire antennas--paying particular attention to the use of a 9:1 UnUn and a good counterpoise system. Here are few thoughts from Peter: The Random Wire Antenna is popular with Ham Radio operators around the world. But how does it work, and does it work! Peter g3ojv, takes a look at it and relates his experience. https://www.balundesigns.com/content/... https://hamradiostore.co.uk/ldg-ru-9-... ----- Thanks for joining us to

ARRL End Fed Antenna Build

Image
The ARRL has partnered with HF-Kits to offer a basic end fed antenna kit suitable for both home and portable use. The kit was designed to give radio amateurs a simple HF antenna for the annual ARRL Field Day Event held during the last full weekend of June. "The SmokinApe" takes us step-by-step through the theory and construction methods used for this antenna.

Beverage Antenna Mechanical Considerations

Image
If you want an excellent receiving antenna for 160/80 meters, you may find this article from Tom (W8JI) most intriguing. This antenna follows suggestions given by Harold Beverage (W2BML) back in the 1920s. Tom does an excellent job of describing the mechanical requirements for this long-length antenna.

Here are some comments from Tom: This is a quick overview of my Beverage antenna mechanical installation techniques. I've been using Beverage antennas since around 1970 with my primary focus on 160 and 80 meters. Beverage antennas like to be close to the ground, but not too close to the ground. Like all antennas, height and length is a matter of wavelengths....not the absolute feet or meters. Optimal height for long Beverages (Length over1 wavelength) is at least .01 wavelengths

Building ladder line by N4LQ

Image
Thanks to N4LQ for this easy, inexpensive method of making balanced feedline and spreaders. Balanced feedline, combined with a suitable "tuner", can make your simple dipole into a multiband HF antenna.

Here are some comments from N4LQ: Here's how to build and install spreader insulators for ladder line. Choose your own spacing. Wire ties should be at least twice the length of the spacer. If UV damage is a concern, try spraying the assembly with krylon UV paint. http://www.krylon.com/products/uvresi... ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Antenna Mast For Ham Radio

Image
If you need a simple, effective mast for your amateur radio station, then this project from Steve (AD4XT) may be for you. Steve shows us how to make a 30-foot/9.146-meter antenna mast from commonly available materials. If you can't see the video, please go here: https://www.youtube.com/watch?v=OSbuHE6-TLE This is post 2784 in a continuing series of simple ham radio antennas. Here are some comments from Steve: 30' Homemade antenna mast for ham radio. I did not want to wait 20 years for a tree to grow where I need one. No guy wires at the height that I am using. Enjoy, 73 I am good on qrz. Ad4xt ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).
