| Subject: | Delta-Pop ADS-B antenna placement |
Having purchased the NavWorx ADS600B and Delta-Pop antenna, I'm trying to figure
out where to install the antenna....
Since the Delta-Pop is a blade-type antenna, it will need to be mounted along the
fuselage direction of flight axis. There are a couple of places where bulkheads
mount to the bottom skin and are aligned correctly. I'm thinking of taking
advantage of one of these bulkheads instead of mounting a doubler plate to
the underside.
Thoughts please?
Thanks,
Ralph

That should work fine. The one behind the baggage bulkhead is off-center a bit
if that's important. I'm getting ready to mount the NavWorx UAT and GPS antennas
on my Navion and both will need to be off the centerline due to skin lap joints.
If you don't have an autopilot pitch servo already make sure you leave mount
it far enough aft to leave room for one near the bellcrank.
You could also put it under the baggage pushrod cover. You'd probably need to offset
it for the cable to clear the pushrod. I don't remember if the flanges go
inboard or outboard so you might need the doubler unless the other baggage floor
panels are removable. That's a shorter cable run and one less bulkhead to
penetrate.

Greg Young

Hmmm...
ADS-B is telling others where you are. ADS-B OUT and ADS-B IN are
supposed to be transmitted and read by aircraft for collision avoidance..
I once had the job of converting electronics in a couple of army Cessna
337's - the front and rear engined beast. There were being returned from
Vietnam and turned over to the FBI for use at home.
The equipment in them was military including things like TACAN and, of
course they used transponders in mode B, the secret identification
friend or foe. All of the interesting stuff had been removed.
But installing the new transponder was a problem. I couldn't find the
L-band antenna that I knew was there. A friend found a funny antenna on
top of the cabin which turned out to be what I was looking for. Why on
top ?? Well, thinking about it the 337's were low flying beasts that
were spotting for the F4's and B52's above and that's what the
transponders were for.
Now we have ADS-B and not only the ground based radar sets will be
looking. It will likely become common for ADS-B IN, in larger, faster,
and higher flying airplanes, to depend on reading your ADS-OUT
information in a way that can be independent of ground facilities.
How long will it be before the instructions get changed about antenna
locations? Will we need two of them?
