I've made this pack for my Axial SCX 10.3 JLUR but its universal for the most part.
Contains:
AM-FM Short Jeep Style Antenna (Very fragile, print a few. Use glue to attach, I recommend waterproof Gorilla Glue (eBay Affiliate link). Use standard supports to print and be very careful when separating it from the supports.)
CB Ribbed Antenna
CB Antenna mount (Will require an M2 bolt)
CB Antenna tip (Print in TPU or may have to scale it up 1% and use glue to attach)
GMRS Shorty Antenna (Mounts on the side of a hood)
