I have a Dual XGPS170 that seems to work OK at lower altitudes, but when we cruise at 40,000 feet, the reception is very spotty, to the point that I am about to give up on it. I use it with FltPlan.com’s GO-app, on my iPhone 6sPlus, in a Cessna Citation Excel, C56X.
What I am doing now is mounting the Dual XGPS170 in the side window of the a/c that does NOT have the electric heating elements using those Command picture hanging velco things that you can get at Home Depot. I contacted Dual, and they sent me the “new style” antenna that they are, apparently, now shipping with the unit. This new style antenna did help, I at least get some ADSB sites now at 40,000 feet, but nothing very consistent.
I was wondering if anyone knew of a inexpensive (under $100) way do get better reception? According to Dual, “The antenna form factor on XGPS170 is a SMA connector. We also recommend using the RG400 cable, and keeping at least 30” between your transponder antenna and the new ADS-B antenna.” The last part is easy, as I’m trying to mount this in the side window. But I just thought of this as I’m writing, unless there is an interference issue with the top TCAS antenna on the roof of the a/c, not exactly sure where that is located in reference to the side window.
An external antenna mounted on the aircraft (those Shark fin looking types) is not going to happen, according to the boss man. So that is out of the question.
Any suggestions would be greatly appreciated.
To clarify what I am looking for, I’m not really looking for traffic information from the XGPS ADSB, we have TCAS for that. Rather it is the weather information I’m looking to get from the ADSB. Especially now that Flight Watch services have been cancelled.
