GPS Antenna in Skyranger

I'm planning to take advantage of the CAA's offer of rebate for equipping with Electronic Conspicuity. This will be a Trig TT21 with the add-on TN72 GPS receiver and an antenna for ADSB. I can find plenty of empty volume for the transponder box and controller but I'd like to know if anyone here has fitted their aircraft with the receiver and antenna and where they put them.

I just had notification that a reply was to be seen here, but it isn't for some reason! Nor do I see this thread in the 'What's New' menu so I'll bookmark this one.

The sender said "Have you got confirmation that the setup is elligable for EC rebate?
I have a TT21 currently linked to a non-certified GPS but would buy the TN72 to go with it if I thought I could get the rebate.
"
From the CAA's notice here https://www.caa.co.uk/General-aviat...d-maintenance/Electronic-Conspicuity-devices/
What equipment is in scope of this rebate scheme?

We recognise that there are a range of EC solutions on the market that manufacturers and communities have developed for their own needs.
The main equipment able to be used on an aircraft for EC purposes currently available (and that a refund can be claimed against) includes:

  • ADS-B Out capable transponder inclusive of GNSS position source (Mode S ES Enabled).
  • ADS-B Out capable transponder without GNSS position source (Mode S ES)
  • Certified GNSS source for Mode S ES transponders (Including a GNSS position sources in line with the recently published AIC2019Y141, example being Trig TN72)
  • FLARM
  • Power FLARM
  • Pilot Aware Rosetta
  • Sky Echo 2
Using Trig TN72 implies the use of the TA50 or the TA70 antenna that feeds the TN72 and that's the basis of my claim for the rebate. I hope that's helpful.

As a sky ranger owner about to install pilot aware, I'd be interested to know where you put your gps antenna. I'm considering the TN72 option as well but PA will feed a gps position to the transponder for ADSB out but just not at SIL=1.

SafetyThird, on what where will you install PilotAware? I thought the GPS receiver was integral to the main unit. Is that so?

edited to pose the question correctly as I was thinking of something else at the time, sorry.

Plan is to use the external antenna kit they supply.

The PA box will go under the dash somewhere with the external gps antenna probably on top of the dash by the windscreen and the other two antennas on the top and bottom of the plane. According to Flylight engineering, you can make a small hole in the skin with a soldering iron and use double sided tape to tape an aluminium ground plane to the fabric and bolt the antenna through that.

Ah, I see. What you propose seems fine but I'd check for the presence of a magnet under the GPS receiver as a precaution against introducing inadvertent compass deviation errors. It'll be quite light in weight and a Velcro method of attachment would seem to be fine, RayP above has that. Coil and secure any excess cable to make a nice job.
I know about melting holes in aircraft skins but I'd rather not if I can have an alternative method.
