for many years (12) I had a 420 on the top on a 78 foot tower in Florida
the tower had 3 sets of guys cables on it.. it made it thought all the
storms we for here but no ice as Florida has none. Just lots of wind. The
worst all the lighting the tower had hit it in all the years it was up. But
the 420 made it thought it all, is now on a tower up north and still
working.

Subject: [Repeater-Builder] DB-420B Side Mounting
Hi, all.
I have a Rohn 45G tower and a Rohn's Universal Sidearm Mount presently
configured with several antennas. I want to rearrange the antennas and
mount the DB-420 for my repeater using the Rohn universal sidearm mount.
I want to use the universal sidearm to bottom and mid-mount the DB420
(the heavy, bottom half of the antenna)near the top of the tower to gain
additional at the expense of a lower wind rating. The alternative is to
bottom and top side mount the DB420 using the universal sidearm, but
lower on the tower. The height difference either way is less than 10'
but the tower is under 80' tall so the 10' can make a difference.
I am in a 70 mph county in North Texas where we get severe weather each
Spring. My question: Would the DB-420 be secure enough bottom and
mid-mounted on the sidearm for additional height? Or is it better to
bottom and top mount the DB420 with lower height but greater wind rating?
Suggestions?
Thanks
Stewart
