A Timber Antenna Mast

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=tWq4tgLH-yI.  This is post 2180 in a continuing series of simple ham radio antennas.

Thanks to Australian radio amateur Peter Parker (VK3YE) for this simple antenna mast project.  Rather than using metal or PVC pipe for his HF antenna mast, Peter finds pine wood a good substitute for more expensive mast materials.

The original mast was 6 meters (19.68 feet) long with a 2 meter (6.56 feet) top section added later.

Here's how Peter describes his mast:

"Timber mast suitable for supporting lightweight wire antennas. The mast is 6 metres tall plus a 2 metre top extension. It tilts over for easy work on antennas. The antenna supports dipoles for 40, 20 and 10 metres, coming off the one feedpoint. 15 metre operation is provided by the 40m dipole. 80 metres is covered by adding loading coils to the 40 metre dipole. The antenna is similar to VK5AH's dipole except there is a dipole for 10 metres instead of 15 metres. VK5AH: http://users.picknowl.com.au/~wavetel... Being timber the mast is suitable as the centre support for open wire-fed dipoles such as the G5RV. Though it has the disadvantage of requiring an antenna coupler, the single G5RV wire is lighter and cleaner looking as one wire replaces three while covering more bands. Since the video was taken the mast has been extended to 9 metres, with a 38mm timber dowel u-bolted to the top portion. To lower wind resistance and make the higher mast less obtrusive at the top the chopping board pictured has been replaced with a much slimmer PVC T-piece. Main items required (from timber/hardware store): * 45 x 90mm treated pine (6m lengths are good) * pole for top extension (and u-bolts for it) * Paint * A few big bolts with nuts & washers * Cement * Cable clips and mounting hardware"

G5RV Multi Band HF Dipole Antenna. Post #1555.

This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation?

In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas.

The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lacki…
