I need to replace the whip on my Atas120a. There are two screws holding the whip in place.  Can anyone tell me what size wrench I need in order to loosen the screws.

Thanks

Can guess at the size, 2.5 to 4mm. I replaced my whip years ago with an "as-is out of the package" Larsen VHF whip, lost V/UHF which I didn't use at the time but the HF just seemed a bit better and if you want to keep V/UHF, trim the Larsen whip.

Oh, if you have one of the Comet or Diamond you may have the correct sized Allen key.

Hope this helps even just a little bit.

I was able to loosen the screws based on Ted's reply (Thanks Ted).  However, the Larsen replacement whip is slightly "thicker" and I can't insert it in the top of the Atas.  Any suggestions.  I can grind the whip slightly or drill the Atas hole slightly.  I'm leaning towards the drill unless that's an issue.
