Thanks to Dave Tadlock (KG0ZZ) for this comprehensive look at making a simple 10 meter ground plane antenna.  The antenna can be placed on a mast or deployed as a ground mounted vertical antenna. Dave takes you step-by-step in the design, construction, and testing of this versatile antenna.  Even though propagation doesn't support much 10 meter activity these days, you can get plenty of local and regional coverage during the day.  Why not start a local 10 meter net, conduct code practice, or join Ten-Ten International to keep the band alive?  Technician licensees also have a small slice of the band for SSB contacts as well as CW and other digital modes. Dave has done a thorough job of explaining how to make an effective antenna at a reasonable price. For the latest Amateur/Ham Radio news and information, please visit these websites: ht

Mark (2E0VOV) has done an excellent job of designing, building, testing, and finally using a homebrew antenna "coupler" for his end-fed half wave HF antenna. Mark says the final design and working project took lots of time to finish with many modifications included in the antenna system.  If you follow Mark's suggestions, you'll have an effective, inexpensive "tuner" that will allow multiband use of your new end-fed half wave antenna.

In this video from Kevin Loughin (KB9RLW), we go back in time to one of the "classic" HF antennas from the 1920s and 1930's.  Kevin's end fed half wave with built-in counterpoise is based on an original 1909 design by German engineer Hans Beggerow, who later used the antenna on Zeppelin Air Ships. Along with other comments, Steve Ellington fills us in on Beggerow's original concept: REPLY Steve Ellington 1 day ago Hans Beggerow's antenna didn't have a counterpoise. That ladder line section was 1/4 wavelength long and acted as a transmission line transformer which transformed the high impedance antenna to a low impedance thus moving the high voltage point far away from the hydrogen filled balloon. It was simpl

Here's another antenna idea from Australian radio amateur Peter Parker (VK3YE). In this video, Peter describes and demonstrates an end-fed multiband antenna for portable use.  According to Peter, the antenna is a "full-sized half wave on 20 meters and a loaded half wave on 40 meters...the antenna also works on 10 meters." Peter shows us all of the steps needed to make this portable antenna.  If you need a high performance antenna for your next mini-DXpedition, you may want to consider this easily made antenna from "Down Under."

Broadband Indoor Antenna. Post 1972.

Here's an interesting antenna project for those living in deed-restricted housing governed by HOAs and CC&Rs. Title: Broadband Indoor Antenna. Author: Igor Grigorov (VA3ZNW). Source: http://www.antentop.org/007html/007_p59.htm Accessed on 27 August 2019, 2200 UTC, Post 1972. Igor designed and built this antenna in 1994 after "heavy winter winds destroyed my outdoor antenna." In this post, Igor describes a very simple antenna "that can work at all amateur bands." The complete article covers three pages and includes the following: Diagram of the Broadband Indoor Antenna. The 9:1 Transformer Circuit. A circuit for testing the RF transformer.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=6TpXibbie1U. Australian radio amateur Peter Parker (VK3YE) currently has 764 ham radio-related videos on his youtube channel.  One of his more popular programs is his "Ask me anything Q &A." The range of topics is quite broad, from antenna design and construction to portable operating and and simple transceiver repairs. At the end of each program (about an hour), he encourages viewers to submit their questions for possible inclusion in this recurring program.  Peter's programs are informal, down-to-earth, and easily understood.  Please check out this program from 23 July 2019 and then submit your question.

How to build an Inverted L for low-bands. Ham Radio Antennas made easy. Post 1970.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=kCq_fOwCLT4. If your backyard or urban property lacks the space necessary for a full-sized horizontal dipole for the 80 meter amateur radio band, then a simple, easy to build Inverted L Antenna may be what you need. In this post, Callum (M0MCX) explains how he made his first inverted L antenna in the summer of 2017 for the IOTA 80 meter contest.  After he built the antenna and learned of its capabilities, Callum said "I loved it...small footprint, some DX capability, and some local activity, too." Why not make an inverted L antenna for your station?
