[TowerTalk] Rohn 25 installation help

[Thomas Viselli]

I am putting up 30 ft of Rohn 25 using a SBH25G hinged base.  I am going to use a Hazer on the tower with a XM-240 40M yagi.  The tower will be guyed at the top.  Any suggestions on how large a concrete base I should use for this installation.  By the way, I know 30 feet is not the optimum height for a 40M beam, but I live on a ridge and the beam will be about 800ft above the valley floor when looking from about 20 degrees to 200 degrees.  Thanks for any suggestions.  73, Tom
