[TowerTalk] Corrosion proofing Elements/connections

[John E.Cleeve]

Without doubt use clear "Waxoyl" manufactured in the UK by Hammerite, 
availble in the USA from motor body factors, especially those dealing 
with UK manufactured vehicles. I have used this material, the clear 
version, since around 1979, when my tower and antennas first went up. 
The application of Waxoyl is time consuming by brush, but well worth 
the effort, for the same yagi is sitting at the top of my tower, since 
1979. I also coated the entire galvanised tower, plus the yagi, not 
forgetting to mask off the antenna insulators. Joints between 
telescopic aluminium sections, opened after thirty years have been as 
clean and shiny as the day they were assembled. Waxoyl is clean to 
use, and easy to remove, just with a wipe, by a cloth dipped in white 
spirit....just enter "Waxoyl" into your search engine, and I am sure 
you will find a local source....one last point, because it is a self 
healing waxy coating, surface moisture will not adhere, and this means 
less chance of ice forming on the antenna etc, during the 
winter.....good Luck, John. G3JVC.
