We recommend cleaning the antenna periodically with denatured alcohol. DO NOT use any petroleum-based products or products such as WD40. After cleaning simply let it dry, WD40 or petroleum based products will attract dirt and debris which will simply make the antenna harder to collapse and extend.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

I alo have problem with antenna.
It's like I need to oiled it a bit to extend, is going hard every time. Any tips? Can I just pull it off, oil with WD_40, let it for a while and put back?
