If I were to use one of those Helix coil antennas, and mounted it under
the seat, would it work just as well as a regular antenna on the roof?

Honestly, you would probably do as well by hanging a megaphone out the
window. CB radios are low power and you need to get every little bit out to
get any practical use from them which includes using a very good well tuned
antenna. RM

PS, Still kicking my rear for selling a 55 Century in 1975 that had less
than 30k on it.
