I built a rickety model of the ring tuned 5/8 like the V5/8 or workman.
My recommendation is that you get an antenna that fits your budget, and performs the best for your money spent. I may be labeled a proCBer, but risking that, I will say there have been times when I have had more frustration getting an A99 tuned than I had tuning the workman type ring tapped 5/8 I built.
It is harder putting together a swing set, or a grill than the antenna mentioned, and much harder getting a good steak than tuning the antenna. But it is worth it on both counts.
I say get the Workman 5/8. If you want it in the air within 10 minutes of getting it, get the A99.
