EchoUAT with SkyFYX - Internal vs External antenna?

[WingsOnWheels]

I mounted my echo in the wing access panel and the gps antenna is inside the wingtip. Working perfect so far.

Looks like mine except I use a WIX 51515

So am I understanding that some have mounted the echo UAT black box on the inside of an under wing access panel? As in the box mounted to the inside of the panel with the stubby antenna mounted through the panel? I know the GPS puck itself can be mounted anywhere it can see the sky. The black box and stubby antenna are what Im asking about. In my old age I'm easily confused, so wanted to clarify before I start drilling holes where I shouldn't!

Dan,
I think what everyone is saying you can mount the GPS antenna anywhere there is fiberglass and not metal above the antenna, it would be best if it pointed up toward the satellites.

The SkyFX-EXT doesn't need a ground plane. Just like a portable's GPS puck. If you look under the foam gasket on the base the white dome shell is plastic and there is a GPS potted in the center with resin. In lieu of a firewall shelf, the RV-6A had a plate mounted directly on an engine mount tube. On the RV-7A it was mounted to engine mount tubes in lieu of a firewall shelf. This position keeps the space needed to access mags, oil filter and firewall-mounted battery clear for easy maintenance while giving the GPS great coverage of the satellites. It is a very solid mounting, although the standoff bushings could be shorter if desired. The aluminum mounting plate firms up the structure and provides protection from latent heat after flight. Time will tell. This photo was taken during install and prior to routing and covering the lead wires with protective nylon sleeve.

That oil filler extension tube is missing the safety wire. Do you know how I caught that? Because I got dinged for it too on my condition inspection last weekend

Folks,
Should we expect a price drop (or any discount) for ADSB Out like the uAvionix EchoUAT during Sun&Fun 2020?
I saw Spruce is selling for $1399 (UAVIONIX BUNDLE ECHOUAT WITH SKYFYX-EXT ALL-IN-ONE RECEIVER).
Wondering if I should wait or go ahead and order this.
By the way, the picture of the antenna attached on the engine mount was great for me to define a place on mine .
Thank you!

That?s been the Aircraft Spruce price for as long as I?ve been watching it. I?ve been looking for a price break for over a year and still nothing.

My EXT bundle came with a short antenna. I assumed it must be installed? Am I reading some of these posts wrong? Don?t need it?

Can you post a picture?
Are you saying that other than the GPS antenna, you have an extra antenna? (would that possibly the UAT antenna? like regular transponder antenna )

That?s the ADS-B OUT antenna. Remember it reads the transponder output from the transponder?s antenna and then has to transmit the ADS-B signal through that little antenna.
