ORIGINAL: suitcase
I drilled a hole just behind the angled former and glued in a antenna tube and ran the antenna out and to the vert stab. It's held tight with rubber band.
For the antenna, I brought it out the back of the radio compartment and used a narow strip of white sign vinyl to tape it to the bottom of the fuse right to the tail (on the outside). It does a 90 deg bend at the back and runs an inch or two up the vert stab.
