I personally wouldnt recommend it here is why.
The dBi gain figures are exaggerated.I know alot of hams who use them for their dual banders. They try them and always seem to switch back to a regular style antenna. The only benefit is the height. If they mount it on the roof and have a garage. The other reason is its not as obvious and more stealthy. Not that anyone has car mounted Cell antennas. The antenna is a 1/4w on VHF, therefore it has no real gain, but with a groundplane the UHF gain in dBd should be close to the advertised dBi figure. I sure wouldnt want to push 110w though that but thats me.
Normally I would agree, but after playing with this one at 70 watts, I kept increasing the power (using an HT and an amp to be able to control output power) to 125 watts. After running that level for a while I decided to put the High power Astro Spectra on it. No problems at all and the gain seems to be for real as i have done a apples to apples comparison with a 1/4 with no gain and was able to make repeaters with the diamond as opposed to the 1/4 wave. Same for simplex operation, range was better with the diamond. (yeah, I know, not scientific at all, but the antenna range at NASA is booked for the next year or so).
As with everything else, your mileage may vary, but my experience with this one hammy antenna has been good.
