I am not aware of any ADS-B *Out* product priced at about $1,500 with or
without being portable or with or without a built-in "WAAS GPS".

I suspect you are confusing this ADS-B Out and ADS-B In. Portable ADS-B
*In* receivers typically include a consumer grade WAAS chipset to locate
the aircraft's own position on weather and traffic displays and to provide
location/navigation data for external PDA/PNA/tablet navigation software.

ADS-B Out in gliders and towplane provides little value over other options
that are actually available, installable and well understood today. If you
want glider-glider and glider-towplane collision avoidance technology
install a PowerFLARM. If you are concerned about other traffic, PowerFLARM
PCAS and ADS-B 1090ES In can help, as can installing a transponder...
especially if the concern is fast jets and airliners.

If you operate under a Class B shelf your towplane will already have a
transponder, and unfortunately will also be required to equip with ADS-B
Out by January 2020. If not already equipped with one you should look at a
Mode-S 1090ES Out compatible transponder like a Trig TT-22. UAT Out devices
would be a very bad idea in a towplane as they won't be seen on a
PowerFLARM.

PowerFLARM would be a great solution if it supported TIS-B and was
coupled with an ADS-B OUT solution. Without TIS-B support, I'm totally uninterested.

Oh jeez what a surprise?

Where exactly is this mythical place you fly? What gliders do you fly today
and with what collision avoidance technology? What glider do you own?
Presumably if it is GA or other non-glider traffic that is your concern
that you have been posting for years on r.a.s. about you have been
operating transponders in your glider(s) for all that time right? If you
fly out of a club and have all these concerns about GS and other traffic
where you fly then presumably you have worked to have all their gliders
transponder equipped years ago, if not why not?

Darryl,
The industry is reacting fast to the clarifying information from the FAA:
http://www.aopa.org/News-and-Video/A...WT.mc_sect=tec
Here is your ADS-B OUT box for $699, including WAAS GPS engine. Only good for experimental and kit built LSAs but a good start.
I have a transponder and PFlarm in my 'experimental' glider but would this be an option for those in high-traffic areas who right now don't fly with a transponder? PFlarm shows ADS-B targets very precisely and obviously ATC would know where you are. What's your take on that, Darryl? Mike S, no need to chime in!
