Why should I make the antenna??

Hello!

I'd say the reason todo it is you can make a better antena than they could sell you (cheaply). Plus, if you do your own the way they described, it doesn't need cleanup (the mould seam just melts while stretching!). So I think it's a win-win situation here! Good luck with your project and have a nice day

They've been doing that for half a century or more in armor modeling. I guess it is easier to teach you to stretch the sprue than it is to attempt to make a slender antenna part. Some old school kits like the former Monogram M48A2 (now reissued by Revell) still have an antenna part provided. It would probably scale out to around the diameter of a baseball bat head in the real world.

I think one of the few armor modeling companies that routinely provide an actual antenna is Revell of Germany. They usually provide a length of stiff wire taped to their instruction sheet.
