Here's my take on the Tri band 2m/220/440 Diamond CR320A (so239) mobile antenna.
So far it is a pretty good antenna. seems pretty solid except where it can be folded up seems to have a bit of warble to it but that is expected. i did some test runs @ 85 MPH with good results on 2m 220 and 440 on the freeway. i am QRP on 220 but was able to make it okay on a few 30Mi + repeaters. tho 2m isnt that great but 220 and 440 is where it really shows its true gain. 2m gain is about what was expected about the same as a 1/4 antenna.
Now here is some close up photos of the Diamond CR320A.
ANLI dual compared to Diamond tri (anli 23", diamond 38").
Diamond folded over
center coils
front to back: Diamond CR320A, 440 phantom, 800-1200mhz phantom.
