The CB antenna broke off, leaving the spring mount unscathed, (probably low tree limb) and is only a stubby now.  I have ordered a replacement, and it is standardized at 48".  I no longer carry a standing wave meter, so does anyone know  approximately how long the antenna should be? Quarter wave of a CB antenna is 108", So I would 1/2 that until I arrive at best (shorter than 48") length, or approximately 27"??  No rush, and thank you!
