Firestik KW7, Original Firestiks design. Outperforms 102 inch whips in a vertical dipole configuration for me. No scientific test just changed the 102 inch whips to two KW7s. Less noise, seems to talk further. Think it looks neat to see the two big blue whips up in the air too. So KW7 or Skip Shooter 7. The KW7 was available to me so I got them.
Isn't a Sirio 5000 a step above a wilson?
NMO Antenex (Laird) CWB27
67.5”
A preference for this was expressed in at least one recent discussion.
The LARSEN NMOCBO-series is another (see discussions).

These guys got it correct.
I used the Sirio 5000 before and it tunes up nice and is wide banded. The only thing I didn't like was the whip is thin and flops around in the wind easily. It is stainless steel and it withstood many tree branch wallops.
After tuning, it's about 78 inches tall.
The Predator 10k antennas single coils get up to around 7ft. These are very good choices if you want the big coil antennas. Fortunately their made of lightweight aluminum so there not very heavy as they look. I still have one of these.
When looking at tall antennas, I would go with center load types. It's the best trade off for durabilty and performance. Top load antennas tend to be better but aren't as durable when hitting objects because you will hit the loading coil instead of a whip like a center load. Base load antennas should be your last choice. Those are for roof top mounts like NMO and puck mounts. The higher the loading coil up the antenna, the better.
Interesting about the loading coil height, does the coil radiate?
It's believed that the coil itself may radiate some being part of the antenna. The coil is an inductor which is a current inside of a magnetic field. This explains why you see a non-conductive stub inside a loading coil like your big metal CB mobile antennas. Any metal in this area would alter the magnetic field preventing the inductance value to match the feed point of a shortened mobile antenna to 50 ohms. Hence the coils purpose.
