M2 Button Insulators / Keepers

[VK8MS/3]

Hi Mark,

I'm not sure what diameter those elements are, but one option might be these 'snap bushings' made by Heyco.

NPA is their distributor in Adelaide

In the past, I've used these for both 2m and 23cm yagis. I use a small amount of epoxy glue to secure the element once I'm happy that it's centered.  No need for those retaining rings.

I've also bought Delrin insulators from Directive Systems, and I note that they list them (and the keepers) for both 3/16-inch and 1/4-inch elements.
I'm using the 3/16-inch insulators on my 70cm yagis.

Hope this helps.

Thanks for the idea Rod, 
I looked them up yesterday and would work great however I was looking for something else today and I found a bag of the M2 3/8"-10mm button insulators, I knew I had some here some where.
Will get the 11 element back together this week.
