Airport; Procedure
The ATIS instructed all helicopters and aircraft from the north/landing 9L contact Tower on the north frequency. Aircraft from the south/landing 9R contact Tower on the south frequency. During peak traffic operating hours the airport uses two frequencies. We were cleared for the Whiskey arrival and continued to the entry point from the southwest. Our flight path took us underneath the approach of 9R. On the helicopter frequency we were not given any traffic that passed directly overhead. We are also not able to hear the south traffic communication because we are on the north/helo frequency. If that fixed wing had been low and we been high then the results......I know neither of us knew the other was there. I think maybe all north operating aircraft should be on the same frequency as well as south operating aircraft irregardless of rotary or fixed wing.
Helicopter pilot reports being surprised by traffic arriving Runway 9R at TMB while he is passing under the approach path on the Whiskey arrival to Runway 9L. Two Tower frequencies were in use and no traffic information was provided.
