Angier,

 

It's worse than you thought.  Garmin GPS WAAS antennas require a minimum of about 13 feet of antenna wire length or a lot of connectors because of some expected minimum loss betwixt the antenna and the magic box.

 

Whoopie should come from you on your first flight - perhaps in this decade.

Hi Scott,

I agree with your comment on 430W, I have it in my Mooney. I also 
agree that TACS capability is of somewhat limited value in the IFR 
environment. As you well know, I began construction of my 360 way back 
in the last century when you were still a twinkle in somebody's eye. 
Had I known about WAAS, I might have at least planned ahead to provide 
for an eventual upgrade. My (new) Apollo GX60 is approaching dinosaur 
status and has no upgrade path for WAAS.

If I got really enthusiastic and all fired up about a WAAS upgrade, I 
would remove my GX60 and SL70  and their trays from the stack. They 
could then start a new life as paper weights on my desk. A new Garmin 
WAAS unit could then occupy that footprint. The SL30 nav/com would 
move to the bottom of the stack and the old transponder would need to 
be replaced with a remote located transponder. A lot of work that 
would interfere with plans to become airborne this year... The only 
part of my gps system that is WAAS compatible   is the RG400 antenna 
cable.... and it runs in a bundle with the 4 9900B, 1 com and 1 marker 
beacon cables on the left side of the cockpit.

I'd be a little bit irritated if I went the upgrade path described, 
only to find out that the 9900B cables were makin' WHOOPY with the GPS 
cable....how's that for electronic speak?
