    I’m interested in 11 meters. I’ve been on cb for 43 years I curently don’t have a leaner set up and I have been reading about texas star
    DX-1600. I will be using it in my big truck that has 4 1100 cold cranking amps. The alt. Is 14.5 volts at 200 amp. Alternater. Does my charging system and batteries heavy enough to get the best performance out of a DX-1600?
    I run a 102″ stainless whip at a 1 to 1 standing wave.
