Flagge

Hello, how you attached the flag to the antenna? Looks like you made a cover over the antenna and the flag is attached with cable ties.

Greeting dream Spyder

There is a lot of force applied to the antenna when you go down the road with a flag flapping it.

You may end up with a broken antenna real quick. :dontknow:

you are stepping into broken antennae territory. There are flag holder made for your trunk that will stand up to some flag whip.
the picture you showed should be considered "show only" and no flag that size is going to last down the road.

Thank you for the information

The picture shows the antenna has been replaced by a small flag pole and the flag is attached to that. There is no antenna it must have been removed. I suppose the owner of that spyder determined a flag with a pole was better than the radio antenna.
