Now that I (finally) have an IFR capable GPS, I need an antenna.\u00a0 I could have purchased one from Grand Rapids for $550, but I decided to check with the manufacture of the antenna they sell.\u00a0 Sensor Systems sold me the same antenna for about $425.\u00a0 Sweet!<\/p>\n

Usually the antenna is mounted top of the fuselage.\u00a0 On aluminum aircraft, you have to put it outside otherwise the metal blocks the signal.\u00a0 That’s not an issue with a composite aircraft.<\/p>\n

Most Velocity builders put the antenna on the canard under the cover known as the “doghouse”.\u00a0 Other builders create a shelf under the doghouse.<\/p>\n

Me and Malcolm went back and forth on the best approach.\u00a0 Under the doghouse and you have lift up the doghouse and reach in to disconnect the antenna before removing the doghouse completely. On the canard and it’s one more thing competing for space in a very busy area with things that move (trim motor and autopilot pitch servo). And it’s got to be elevated to allow for the antenna cable.<\/p>\n

In the end I decided to put it under the doghouse.<\/p>\n

So Malcolm did what Malcolm does best: Create things out of resin and fiberglass.<\/p>\n

Here’s the GPS Antenna Shelf.<\/p>\n
