RobertGary1 Posted August 21, 2017 Report Posted August 21, 2017 Avionics shop says that the external antenna may be unnecessary if the unit can pick up a signal without it. For planning purposes I'm curious how many found the external antenna was required. -Roebrt Quote

Jim Well that's what I thought but the Garmin dealer is telling me that if the signal is sufficient the external antenna isn't required. The shop is 2 hours drive away so I don't want to have to return if I end up needing it. I'm also installing a GTX345 with internal WAAS but he says they won't share. -Robert Edited August 21, 2017 by RobertGary1 Quote
RobertGary1 Posted August 21, 2017 Author Report Posted August 21, 2017 Here is what I see in the install manual... "The G5 includes a built-in GPS receiver with an internal antenna that can be used in many installations. A Garmin or non-Garmin GPS antenna is optional for G5 installations when not using the G5's internal GPS antenna. See Section 1.4 for supported antennas and antenna requirements." Quote
Godfather Posted August 21, 2017 Report Posted August 21, 2017 (edited) The external antenna or waas source is required for the G5 installed in the AI or TC location. It is not required if installing in the DG/HSI location. However, the magnetometer is required if installing in the DG location. Edited August 21, 2017 by Godfather 1 Quote

I only ask because there are a lot of rumors about the install but I want to point the Garmin dealer to something citable. -Robert Quote
Piloto Posted August 21, 2017 Report Posted August 21, 2017 Another option for GPS antenna location is underneath the glareshield. When I was subscribed to XM/WX I had the XM antenna installed as shown on the picture. I works very well. José Quote
RobertGary1 Posted August 22, 2017 Author Report Posted August 22, 2017 I think the glareshield would work in the J but not the F. -Robert Quote

I love easy access to the back. A friend of mine has the mod and it's a huge pain trying to find children to put their hands in the little panels. I end up there at annual but also seems like no shortage of electrical things to trace down -Robert Quote
