Need help with Diamond discone

[bobruzzo]

I have a Diamond discone antenna purchased in 2019. Since then I have upgraded to different antennae. One problem is I LOST the bolt that secures the aluminum mast section to the feed point area of antenna. I dont know what kind of bolt it is as far as thread size/spacing. And I cant take the antenna into Home Depot. I may have to write to Diamond and ask them if I can buy a replacement.

You can take the radials off and bring the centerpiece to Depot or hardware store. Search diamonds site. They may list it with specs. Make sure whatever you get is stainless.

Chance of finding what you need at HD or Lowes is next to nil. Maybe an old fashioned hardware store, but I kind of doubt it.

Here is an exploded view that may help.

Assuming it is ‘Screw M3’ part number 01013 that is a 3mm bolt. If I remember, it is only about 10mm long.

Lowes and Home Depot have a good selection of stainless bolts in plastic bags.

Checking on Amazon, there are sets of 3mm and 4mm stainless bolts for around $10.00

My elderly neighbor once asked me what that "broken umbrella" thing was that I mounted to my chimney - hihi it was a new discone.

I think Fixitt's advice is great. Those tiny set screws are a big headache if you loose them. If you have a mechanical-savvy friend they can possibly tap a new hole and put in a replacement of a different size.

If the thickness of a screw are close to 3mm then its a M3 and if its 4mm it is a M4. If you lose one of those insex screws that holds the lower radials then measure the thickness of one of the other screws, its probably M3, and buy one with a hexagonal head that will be easier to use with a spanner, instead of the insex or screwdriver head types. The length of a screw doesn't matter for the function of the antenna.
