OTAMap

Works for both FM and TV! Loaded with new features in 2.0!

Use OTAMap to find and point your antenna to all your Over The Air (OTA) television and FM stations.

OTAMap gives you the latest Over The Air (OTA) television/FM station information. for all of the continental USA, Alaska, Canada, Hawaii, Northern Mexico and some US territories such as Puerto Rico.

OTA Map will list all OTA channels/stations within 150 miles of your current geographical position as indicated by your iPhone/iPad. With this tool you can quickly see what OTA stations may be available in your area.

With OTAMap you can view the position of the transmission towers, of any of these Over The Air television stations, in relationship to you. This can be used to help adjust your HD OTA antenna for local reception, for that hard to get station, or even the far far away channel that you have been trying to "DX" for quite a while. Whether you are on your roof or turning your rotor from your living room, OTAMap can help you.

*****Note to Northern Canadian Users: OTAMap does work everywhere in Canada (including Edmonton), however you may need to flip on the Industry Canada Data in the preferences.

Some of the new features in 2.0

-Street Address (IOS 6.1 and higher only)

•Download and update latest FCC station data anytime.

•Fixed magnetic declination (no longer IRC dependent) (may be off as you near the Arctic Circle).
•Added ability to add stations/save maps to a DX list. The list can be pulled up anytime and the pointing maps reviewed.
•Added Super Contour Map. Given a particular location it -will list all stations that fall within the 41/60 dBu contour map which should indicate stations that should be received relatively easily.

•Now works for all of the Great White North - Uses IRC data for anything not included in the FCC database.
•In the station pointing map view the map can be updated if the users gps determination has changed.
•In the station pointing and the all station map views, you can drag the home icon to say a different part of the roof/yard and the calculations will follow.
