So you guys got me thinking, after looking at these elements and measuring it realized something... these look like Aluminum Arrow shafts, and the inserts might be the arrow broadhead insert.. which all parts are readily available at most sporting good stores for building you own arrows (yes I am a hunter and used to bow hunt)
The commercialised Arrow design was based upon an article on using arrow shafts in an antenna.
Not a surprise at all. ;)
I will double check this and let you all know, I'll have to do this later today after I'm off work.. but if this is the case replacements should be very easily created.

Ahh yes, my mistake... Anyway there is a spare parts list that came with the antenna (I have it) but it does not list size, it says 2 - 1/4 stud.. but that does not answer your question..
If you need this list or would like it I can scan it and post it or send it to you..
Sorry for the confusion

If I recall correctly they are the same size as a camera tripod.. so they would be a 1/4-20
I was going to answer this then realised he is really talking about the elements themselves? I've not looked yet.

Does anyone know the screw size/threads used for the elements on the dual band Arrow Antenna?
I have some that are a little bent and want to start looking for replacements and maybe buy some spares as well.
