I agree not only does the Amatuer Radio Relay League Offer solutions for these types of problem's but also you can find there reference at major city libraries that is just packed full of reference to everything from signal loss problem solving to transmitter schematics, It's the best option, and I am sure if you go to a fry's electronics there will be a rack backlogged with the monthly magazine "The ARRL antennea compendium" and no doubt one will contain a solution to a cellular band antenna troubleshooting situation.

But you can always turn your congloborate slave of a business into a museum, That's the only archivial means of preserving your right to have your own insurance, produce your own diy audio video recording wares. Preserve the artifacts considered obsolete, and teach about there inner workings, hell reproduce your own dvd's and then just leave the door's unlocked so people in the neighborhood can use the space and security of its wall's and locker's, this way you don't have to pay for increasing insurance prices and you still have your business, until the hammer comes down of course.
