I’ve purchased a K4KIO Broadband Hexbeam (20m-6m). The below documents my journey. It is currently 10M AGL due to limitations with local council requirements.
Items used:
* Yaesu thrust bearing
* Top post between hex and rotator (aluminium)
* NBS Tilt/winch up mast – https://www.nbsantennas.com.au/
* Yaesu G-450C rotator
* A lot of concrete (32mpa) for the footing.
* Brinlays Paints – https://brinlaypaints.com.au/
Stage 1: Painting the spreaders
The fibreglass spreaders are pretty much just that, fibreglass so over time, believe it would weather therefore K4KIO recommended to paint the spreaders which will result in longevity. There was discussion re Rustoleum in a can but at $15 per can here in Australia, its expensive. Ended up getting an equivalent in paint from Brinlays Paints which has the same properties.
Two coats of this primer, then two coats of a product called Sun guard which is an outdoor paint. Quite thick stuff. End results are below.
Stage 2: Lightweight rotator
Yaesu G450 has been purchased and set up with trailer wire. Cheap alternative to getting the yaesu branded control cable. Works the same and is built to withstand the environmental punishment.
Stage 3: Hexbeam assembly
Stage 4: NBS Mast build
Stage 5: Final Product
After months of planning and $$, its all complete. Installation on a NBS Antenna mast @ 10M above ground level.
- Coax – Times Microwave LMR400 Ultraflex
- Yaesu g-450c rotator
- NBS winch system mast
Could not be possible without Adam (VK2PW) & Bradley (VK2BY). Absolute gentlemen!
