Dual antennas

[batmobile]

i like the look of the dual antennas, think i might fill in hole from original on r.f. fender, and relocate to rear. if i did this, which is just a consideration at this point, i would like to do 1 for the radio, and 1 for a c.b. radio. with the two different types of antennas so close together, would that cause interference? does any one have good pictures of where and how they r mounted?---jeremy
