I used Champion Radio's WinMARC tool to calculate the recommended masts for
my planned VHF/UHF stack. If I enter an extra safe wind speed of 100 mph
(my county is 70 mph basic speed), the tool suggests the following masts:
Wall Yield Strength Description
---- -------------- ------------------------------------------
0.120 40,000 6063-T835 Drawn aluminum tube
0.120 42,000 2024-T3 Drawn aluminum tube
0.120 46,000 A 500 Grade B Structural steel pipe
0.120 50,000 1010 Carbon steel CDBW
Of course, something even stronger could be used, but just adds extra weight
I need a 10 foot mast and that's too long to ship via UPS, etc. So I'll
need to obtain locally in order to avoid multi-$100 freight charges. But, I
suspect if I took this list to a local hardware store or Home Depot or
Orchard Supply Hardware, they wouldn't have a clue.
So, my questions are:
1) Does any of this stuff have a "common" name?
2) What type of place would I go to look for it?
3) How can I tell that I'm getting the right stuff?
I'm in the S.F. Bay Area (peninsula), if that helps.
Thanks in advance,
73,
Michael - K5MEF
