I have been verypleased with their 40m beams and I found DF2BO to be a pleasure to discussantenna design with.https://www.optibeam.net/index.php?article_id=1&clang=1  I am also seeing posts that SteppIR is ceasing production on consumerantennas and accessories which is bad news for all of the SteppIR lovers:https://www.dxzone.com/steppir-to-cease-consumer-antenna-production-by-august-2025/  John KK9A  Tommy  k6ye wrote:Steve, WiMo, the new owner of Optibeam< has it on their website.

I iam just using it until I can find a way to easily replaceit, which is not a likely scenario.My bearing is 2.5 years young in a salty coastal location.Al  N6TA On Sat, May 24, 2025 at 9:12?AM <towertalk-request at contesting.com> wrote: > Send TowerTalk mailing list submissions to>        towertalk at contesting.com>> To subscribe or unsubscribe via the World Wide Web, visit>        http://lists.contesting.com/mailman/listinfo/towertalk> or, via email, send a message with subject or body 'help' to>        towertalk-request at contesting.com>> You can reach the person managing the list at>        towertalk-owner at contesting.com>> When replying, please edit your Subject line so it is more specific> than "Re: Contents of TowerTalk digest..."> Today's Topics:>>    1. replacement top plate bearing (John Keating)>>>> ---------- Forwarded message ----------> From: John Keating <john.keating at outlook.com>> To: "towertalk at contesting.com" <towertalk at contesting.com>> Cc:> Bcc:> Date: Sat, 24 May 2025 01:18:32 +0000> Subject: [TowerTalk] replacement top plate bearing> I need to replace the rusted out bearing on the top plate of a tower.

The collar has the advantage that it can be split, and in most cases installed with no? gymnastics involved; just a little ingenuity. Might need to drill a few new holes in your top plate. -Steve K8LX On 05/23/25 9:18 PM, John Keating wrote:> I need to replace the rusted out bearing on the top plate of a tower.
