Yes, Sentry can be used with any mount that has a ¼”-20 bolt (same as a standard camera tripod). See this article for an explanation of how ADS-B towers and ADS-B Out capability affects traffic picture. If you are not in range of any ADS-B towers, you will not see any weather in ForeFlight and your traffic picture will be limited to nearby ADS-B Out equipped aircraft. If your aircraft has an AC-heated front windshield, try mounting Sentry on any non-heated windows to see if reception improves.Īircraft Location: It is normal to receive little or no ADS-B tower reception below about 1,000 feet AGL since ADS-B signals depend on line of sight. Heated window solutions that utilize direct current (DC) do not block radio signals, by contrast. Sentry’s Location & Orientation: Mounting Sentry upright on a side window will provide the best reception, but if no side window is available you can also mount Sentry on the dash with the status lights towards the front of the aircraft.Īircraft Configuration: All ADS-B receivers have poor reception through alternating current (AC) heated windshields, as the construction of such windshields tends to block ADS-B signals. Reception is dependent on a number of factors, including Sentry’s location and orientation in the aircraft, aircraft configuration, and your aircraft’s location. HOW CAN I MAXIMIZE SENTRY’S INFLIGHT RECEPTION? See this article from iPad Pilot News for an explanation of how having ADS-B Out capability affects your traffic picture. The traffic displayed by Sentry may not represent all nearby traffic, especially if you have not yet installed an ADS-B Out transmitter in your aircraft. WILL I SEE ALL NEARBY TRAFFIC WHILE USING SENTRY? Scout, Sentry, and Stratus portable ADS-B receivers will support delivering these weather products to the ForeFlight display. In a future app release, ForeFlight Mobile will support the six new FIS-B weather products that the FAA is adding in 2018, including: Lightning, Turbulence, Icing, Cloud Tops, Graphical AIRMET, and Center Weather Advisories. Will Sentry support the new FIS-B weather products the FAA will introduce in 2018? Keep in mind that if your aircraft is not equipped with ADS-B Out, then you will have a limited view of traffic on ForeFlight.Īdditionally, Sentry has a dual-band ADS-B receiver, integrated CO monitor and alarm, up to 12 hours of continuous battery life, built-in WAAS GPS, backup attitude (AHRS), barometric pressure sensor, onboard memory for Weather Replay™, and supports up to 5 devices. ![]() Sentry can also receive air-to-air traffic information from ADS-B Out equipped aircraft and re-broadcast traffic information (ADS-R and TIS-B) from FAA ground towers. ADS-B ground station reception will usually not be available until airborne. When in proximity to a ground station, Sentry also receives FIS-B weather, NOTAMS, and TFR information. Sentry receives traffic information on both UAT (978 MHz) and 1090ES (1090 MHz). Yes, Sentry has internal antennas for both UAT (978 MHz) and 1090ES (1090 MHz) frequency bands.
