I've got one on a retractable tower at 72 >feet and it works great on all the bands! The 5BA is not a great antenna mechanically. We have a (supposedly) 120mph rated one at a club station which has never seen winds over 106mph (calibrated wind gauges close by). The failures so far? The back element fell off, the 20M driven element rotated on the boom and a few of the boom joints are failing. I have a picture of the 20M driven element rotated on the boom if you're interested. All the failure points are rivets that were installed at the factory so an installation error is not to blame. Avoid.
