A Timber Antenna Mast
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"
