They will be useless in no time . Initial LTE rollout was on 700 mhz . But Verizon is now putting LTE on 700 , 800 and 1900 mhz . For an amplifier to be true LTE it will have to cover all those frequencies and be tri band . As mentioned many times before LTE is mute point for chasers . It is only in Urban areas at this time . Do not expect in rural areas till 2014 . Avoid 4G for awhile if using for chasing as they are still having major hand off problems between 4G and 3G . I know this first hand as we are working directly with Verizon providing amplifiers to try and resolve the issues. Everyone is working on releasing a tri band amplifier but keep in mind it has to be prototyped , FCC approved then produced . So Companies can announce they are going to release one all they want , but when it hits market for actual sale is very questionable as there are many hurdles to get over.
