Cross Country Wireless have released a HF Active Loop Antenna with a frequency range of 200 kHz to 70 MHz with extended coverage up to 148 MHz. The antenna can be for all LF, MW and HF professional monitoring and short wave listening. It can also be used for VHF FM reception and will give useful VHF airband reception when mounted outdoors. The antenna is a triangular loop antenna 1.3m (51") wide with a built-in low noise high dynamic range RF amplifier. A base unit allows 12V power to be fed up an ethernet cable feeder to the antenna. The antenna current consumption is 150 mA . The base unit also has a two way splitter to provide two separate RF outputs. Lo

Excellent tutorial on how to use an antenna analyzer by Randy Hall (K7AGE).

A nice quick weekend project from "tmarinos". Tape measure yagi antennas for 2 meters are easy to build, test, and use. These antennas perform remarkably well, considering the material used--some coax, a few connectors, some PVC pipe , and some steel tape measures from the nearest home improvement or neighborhood hardware store . These antennas can be be used for Radio Direction Finding ("foxhunts") or for emergency and portable use.  The antenna described in this video works very well and didn't cost a lot of money.  You may have most of the antenna materials in your shack.

An excellent tutorial on how to build a portable crystal radio using a loop antenna coil inside a pizza box.  The coil that the tuning/variable capacitor resonates serves as the antenna by being a very large coil.  According to the maker, "Rimstar.Org," radio stations are found by adjusting the tuning capacitor and pointing the face of the loop at a nearby radio station. This crystal radio uses a crystal earphone and a germanium diode (1N344, 1N60, 1N91, 1N270, 1N277, or a 1N283).  Silicon diodes can be used, but the antenna may need more wire to pick up a station.  For more details, visit the author's website:  http://rimstar.org/science_electronic.  Music in this video is "The Path of The Golden King", by Kevin MacLeod (incompetech.com).  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are upda

Where there's a will there is a way, especially where stealth antennas are concerned. Nancy lives in a community for people over age 55 and older.  Her home association banned her from putting up any kind of antenna.  John Amodeo (NN6JA), the producer of the hit television program "Last Man Standing," and his friend Julian Frost (N3JF) travel to Florida to see what they could do to make a 39-ft/11.89 meters antenna fit into a 23-ft/7.01 meters attic space.  The final product is neat, clean, and totally invisible.  Best of all, the highly modified attic antenna works and lets Nancy enjoy amateur radio without the stress of HOAs and CC&Rs forcing her off the air.  An great example of amateur radio operators heldping each other.  For the latest Amateur Radio news and events, please check out the blog side bars.  These news feeds are upda

This time, Dave uses common materials from around the house and workshop to design, build, and use a simple 2 Meter Yagi Antenna made from metal coat hangers .  Since metal hangers are getting rare these days, you can use brass rods, copper wire , or even the old aluminum elements from an outdoor television antenna .  I've built a few of these crude yagis in years past and have found them very useful on portable operations or in locations where I'm a good distance from a 2 meter repeater.  This would make an excellent weekend project.  Have fun!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.
