That looks a nice installation with just that top antenna and nothing on the bottom.
I wonder why they offset the big antenna to the left of the centreline? Is there a U-channel there? There is on a TB so all the rear antennae are offset.
As far as I know, yes. But to be honest, I never asked myself why they have put the antennas on a certain position.
A number of avionics installers have said to me that on any practical plane it is impossible to comply with the minimum antenna spacing requirements in the TAS product IM, so they install the stuff and “hope for the best” and usually it works well enough…
Nice, I will try to get one from US next week.
I’m a bit confused right now, as they have many options beside ADS-B OUT and ADS-B IN traffic and weather, such as TAS, TCAS Class 1, eTAWS, Aural Warnings, all with strange names such as Next-gen Active Traffic or Antenna Diversity.
It’s also not very clear which options can you add later if you buy a basic model first, without having to ship it back for hardware upgrades later.
Take this for example, from their Lynx NGT-9000 manual:
Traffic Advisory System (TAS)
The Traffic Advisory System (TAS) is an optional feature of the Lynx NGT-9000. This feature provides the capability to interrogate nearby aircraft transponders and issue Traffic Advisory (TA) alert as well as a voice audio output that announces Traffic Advisories and relative altitude to the flight crew. This option requires the installation of a directional antenna.
Traffic Alert and Collision Avoidance System(TCAS)
Release 3.0 or later. The Traffic Alert and Collision Avoidance System (TCAS) is an optional feature of the Lynx NGT-9000. This feature provides the capability to interrogate nearby aircraft transponders and issue Traffic Advisory (TA) alert as well as a voice audio output that announces Traffic Advisories and relative altitude to the flight crew. This option requires the installation of a directional antenna.
Can any of you understand what is the difference between the 2 options (TAS and TCAS)?

I am not really sure what you get by going from TAS to TCAS unless it is TCAS II. TCAS I which is what it looks like they are offering is only about warning of traffic (a traffic advisory). Essentially same as TAS. TCAS II gives you a a TA as well as an RA (resolution advisory) which is a vertical instruction to avoid the other traffic.
TCAS2 involves the two transponders negotiating which one will tell which pilot to climb or descend.
It is not applicable to GA.
I wonder what these special cables are…
In GA avionics, the RG400 is the state of the art 50 ohm coax and while at €5+/metre it is avoided by most shops, nobody should use anything less. But above that there are only real specialist cables, with extra low loss in the high-GHz region, and they usually have strict minimum bend requirements because they are air spaced and if you bend them too tight the air gaps collapse. Some are semi-rigid (solid copper, or in the satellite versions solid aluminium, outside tube). I have used semi rigid coax and it would be a bugger to run along the aircraft, but possible.
Google digs up this
Does anyone have the Lynx installation manual?
