Re: [TowerTalk] Securing vertical to concrete post?

[Gary K9GS <garyk9gs@wi.rr.com>]

Permanent installation on a dock piling.I would be securing something like a 
BigIR or DX Engineering vertical.The DX Engineering tilt base normally mounts 
to a 2.5-3" diameter pipe.  
See:https://www.dxengineering.com/parts/dxe-va-pivot-3?fromname=Gary+Schwartz&fromAddress=gschwartz%40wi.rr.com&toAddress=garyk9gs%40wi.rr.com&message=&wishlistid=&mailtype=Item&itemgroupname=&currentItem=DXE-VA-PIVOT-3&storyGroup=&storyName=&x=85&y=18I
 could fashion some kind of heavy duty adapter plate to go between the tilt 
base and the post.I currently have one of these bases holding an 80m vertical 
to a 6X6 wooden post.  Instead of using the U bolts that would normally go 
around a steel post, I pass bolts through the 6X6 and use a backing plate on 
the opposite face from the antenna base.  Obviously something I can't do with a 
concrete post.  I've thought of fabricating a large SS U bolt from all-thread 
and clamping the post with a large AL plate.  Not sure how easy it would be to 
bend the all-thread though in a 10" diameter bend.That's assuming I can buy SS 
all-thread.73,Gary K9GS

Securing vertical to concrete post? Is this a temporary installation or
