An easy solution for mounting antenna is to use plexiglass or acrylic from the hardware store. 1/8" thick plexi is readily available. You can cut it with a saw or score and break it into a 1/2" strip. Then using a heat gun, it can be bent, twisted and manipulated to conform to whatever angles or surfaces you need to mate it to. Secure with 3M VHB double sided tape. That's the tape that GoPro mounts use and once it is set, it's very firmly attached. A small patch, .5x.75 inches is typically adequate yet will release if needed.
