Monroy ATD-300 & ProxAlert R5

[[email protected]]

I started this thread on rec.aviation.products, but I'm also interested
to find out if anyone here has done a panel mounted installation of a
Monroy ATD-300 or a ProxAlert R5? If so, where did you mount the
antenna and how well does it work?

--------------------------------------------------------------------------------------
At the risk of reopening some conversations that were archived from
2004 & mid-2005, does anyone have any up to date experience with either

the ProxAlert R5 or Monroy ATD 300 collision avoidance systems? I've
got a SureCheck TPAS 110 that I have found to not be very useful due to

sporadic readings and the lack of altitude feedback. I also used to fly

a G-1000 equipped C-182 with TIS that was great for traffic alerts (in
regions where TIS was available).

I now have an experimental aircraft where I'm looking for something I
can mount in the panel that will provide useful collision avoidance
information. I'm assuming panel mounting one of these systems will mean

I can set the antenna up permanently in the aircraft so the antenna
positioning issues won't be as much of a problem for me.


The Monroy ATD-300 and the ProxAlert R5 both look like options. The
Monroy looks like it is better suited to be panel mounted, but I've
seen a lot of reports of inconsistent dist & altitude readouts (all
more than 1 year old).


Since most of the Aviation Consumer and newgroup feedback on these
systems is 1 year+ old, and there was talk that all of the competing
companies are consistently addressing these issues, does anyone have
any recent experience with these units purchased in recent months?


Thanks,

We have the ATD-300 in our panel. All mounting hardware comes with it.
Monroy recommends installing the antenna observing two criteria:

1. At least three feet from XPDR and DME antennas.
2. On the belly and as far forward as possible, best in front of the
nose wheel.

We did all that - and it works very well. The reasoning behind point 2
above is that this equals out damping effects by the engine blocks of
both your aircraft and the target aircraft. Consider the XPDR antenna
is mounted on the belly. That means that for a target above you, the
Monroy antenna will "see" the targets belly antenna through your engine
block. If the target is below, the Monroy will "see" the signal through
its engine.

That's what they told me. All I can say is: It works. There are several
pictures of installs at http://www.monroyaero.com/Installation.html and
http://www.monroyaero.com/Testimonials.html.

Yes, my wife also sells them in her pilot shop. But you know all that
from the old threads you found, I'd assume...

Thanks for the feedback on the Monroy ATD-300. That one sounds like the
easiest to panel mount.
