Too bad about your Predator antenna. The ones I have seen were rather large and had a internal motorized matching device along with the antenna motor, nice design I thought.
Since Predator is no longer in business, a direct replacement is not likely for the motor.
I use Tarheel antennas and been happy with them. They are the only ones that offer a wide assortment of antenna mounts and accessories. They make antennas from 4 ft down to 2 ft. with high power (legal limit) to 500 watt and 150 watt low power models too.
Scorpion antennas look to be well made and have a beautiful look to them and their antennas use 3 in. diameter coils. They are the more expensive screwdriver antenna and are heavy so a good sold mount is required.
HI-Q makes some interesting screwdriver antennas with many variations and should be looked as well.
The Yaesu ATAS 120 is really proprietary for Yaesu radios. MFJ does make an interface device so you can use that antenna with other radios, but the antenna will not auto-tune like it will with Yaesu radios, it will simply manual tune.
There maybe a few more independent antenna makers but those mentioned above is about it for commercially made ones and these manufactures have been around a while and will probably continue to do so.
Hope that helps you with your decision.
