[evlatests] [Vlite-external] Antenna ea1=V5 problems

[Doug Scott]

Good afternoon,
As one of the techs who swapped out the L305 here, I'd like to request a 
little direction on how to minimize any impact on VLITE modules.

1. Of the many modules we (LO/IF) affect in the antenna vertex room, 
when are we to request our VLITE expert to check things out?

2. Should the VLITE expert (Mike R.) be unavailable, who might be 
filling in?

3. Is there an antenna overlay screen in the works for VLITE?

Thanks,
Doug
