The only way to properly tune the antenna is to do it in situ. The A99 has tuning rings at the bottom so you should be able to do it fairly easily after the installation.

Bolt it to the pole, stand it up in a garden parasol stand if you have one and tune it. That way you may be lucky and have it near as damnit when it goes up .

The Antron 99 should be set already by the company, i used mine straight out of the box set on a 24 foot pole without the ground plane kit, swr's right around 1:2 across the mid frequencys (U.S CB frequencys).

Don't expect the TV guy to have any clue about how to tune the antenna.
I've had a few A99s and Imax 2000s, never needed to touch the tuning rings. Don't get hung up on getting 1:1 SWR, there's no benefit. As long as it's below 1.6-1.8:1 on the channels you operate on that's just perfectly fine.
